4.1. Cleaning the Scanner To keep the scanner in good operating condition, ensure that it is free of accumulated dust, ink, grease, and other contamination. The scanners are high resolution optical instruments with high quality glass parts. Since a higher quality scanner makes smaller dirt and dust particles more visible than a low quality scanner, special care must be taken to keep all parts and especially all glass parts as clean as possible.

4.2. Cleaning Intervals Cleaning intervals are determined by the scanner environment and, the types of documents scanned and the usage frequency. The scanner should be cleaned under the following circumstances. ➢ When sporadic or frequent image quality problems occur. ➢ When sporadic or frequent transport problems like skew and slip occur. ➢ When parts like rollers etc. look dirty. ➢ When a service of any kind is performed on the scanner. An onsite visit by a service engineer should always include cleaning.

4.3. General Cleaning ATTENTION! To prevent electric shock and other potential damage, make sure that the scanner is switched OFF and unplugged before any cleaning is performed. Do not let any water get inside the scanner. Proper general cleaning should include the following: ➢ Use an electric dust cleaner to remove dust from all parts before you continue cleaning other parts of the product. Be careful not to touch parts with the dust cleaner hose. ➢ Clean the outer surface of the product with a damp cloth. Wet the cloth and wring it out as much as possible. The best results are obtained with a microfiber cloth. ➢ Use a mild soap and water solution only if necessary. Do not use abrasive cleaners. ➢ Wipe the product dry with a soft lint-free cloth.

Service Manual WideTEK Scanners

Page 9 of 133

4.4. Cleaning the Drive Roller Drive rollers on WideTEK sheet feed scanners as well as WideTEK ART scanners are manufactured from EDPM rubber, which is light gray in color. The reason for the light gray color is that you can detect whether they are dirty or not. If rollers are dirty it can affect the driving properties, skew and slip of the documents can easily occur. To help with the cleaning, the sheet feed scanners have a control for the drive rollers on the touchscreen. ➢ Use a lint-free cloth and dampen it with isopropanol alcohol or glass cleaner. ➢ Let the rollers rotate and gently hold cloth against the roller. Repeat for all rollers until they are clean. ➢ The older WideTEK CIS scanners have two pairs of rollers, one pair is driven actively and the other is idling when the scanner is open. Turn the idling rollers by hand to clean them.

4.5. Cleaning the Paper Path, Pressure Rollers and Background Drums The pressure rollers are ball bearings made of stainless steel. They should not accumulate much dirt due to their smooth surface. The background drums are either made of paint coated aluminum (WT36/44/48) or made of PVC (WT36/48C, WT36/48CL. Both should be treated carefully. ➢ The background drums on WideTEK CCD scanners can easily be removed before cleaning. Make sure you do not lose the bearings at the two ends of the drum. ➢ If you have to remove any of the other parts for cleaning, use a hexagon head ball screwdriver, size 2 mm and remove the paper guide sheet metal. ➢ Clean the pressure rollers, the background drums and the paper path with a damp cloth. Wet the cloth and wring it out as much as possible. The best results are obtained with a microfiber cloth. ➢ Use a mild soap and water solution only if necessary. Do not use abrasive cleaners.

ATTENTION! If the background drums have significant scratches which change their color (especially the black drum), you can repair them by covering up the scratch with a little bit of paint used to repair the paint on cars f.e.

Service Manual WideTEK Scanners

4.6. Cleaning the Scanner Glass Normally it should be sufficient to clean the scanner glass from the outside. All glass parts should be treated carefully. ➢ Clean the outside of the scanning glass with a damp cloth. Wet the cloth and wring it out as much as possible. The best results are obtained with a microfiber cloth. Do not use abrasive cleaners. ➢ If dirt persists, use a lint-free cloth and damp it with isopropanol alcohol or glass cleaner. ➢ If it is necessary to clean the inside of a scanning glass, you must be extremely careful to avoid that more dust gets into the scanner. Move the scanner to a clean area with as little as possible air movement from heaters, air condition or open windows and doors. Make sure you have enough light to control the cleaning results. ➢ Try cleaning all accessible areas of the scanner as well as the surface of the glass with a dust cleaner. Do not touch any parts with the dust cleaner.

4.7. Cleaning the Camera Box Normally it should be sufficient to clean the scanner glass. If it seems to be necessary to also clean the protective glass on the outside of the scanner box perform the following steps. ➢ Try to brush off any dust with a soft brush or clean compressed air if available. ➢ If this does not help, clean the outside of the camera protection glass with a damp cloth. Wet the cloth and wring it out as much as possible. The best results are obtained with a microfiber cloth. Do not use abrasive cleaners.

ATTENTION! Never open a camera box, there are no serviceable parts inside. If you do open it, the warranty is void. If a camera box needs replacement it will be repaired in the factory. Depending on your service contract you may get a replacement camera box upfront.

6.1. Description of White Balance The first diagram shows the red channel of the camera signal of one CCD line. The area marked by the blue rectangle is the useful pixel range which in most camera systems marks 7.200 pixels out of 7.500 total. It is noticeable that the signal varies from left to right while the edges have the least signal. The white balance procedure will correct this and the result is shown in the second diagram.

Camera signal, uncorrected, 7200 useful pixels

6.2. White Balance Target The target used for the white balance depends on the scanner. Initially three targets are shipped with every scanner. They all look similar to the one shown on the picture. The height of the target is 350mm and the width varies with the size of the scanner.

ATTENTION! Impairment of the scan quality can occur if an improper test target for the white balance is used. The most noticeable effect is the appearance of streaks of darker or brighter content in the scanning direction. These are the targets used for WideTEK scanners: Target Size Scanner WT12-WA-01-A 340 x3 50mm WideTEK 12 WT25-WA-01-A 660 x 350mm WideTEK 25 WT36C-Z-01-A 960 x 350mm WideTEK 36, WideTEK 36C, WideTEK 36CL, WideTEK 36ART WT48-WA-01-A 1280 x 350mm WideTEK 48, WideTEK 48C, WideTEK 48CL, WideTEK 48ART

➢ Make sure that the test target is free from wrinkles, discolorations, cracks or other damage. ➢ Store the test target for the white balance in a safe place protected from daylight.

6.3. Perform White Balance It is mandatory that the scanner is absolutely clean before a white balance can be performed. If the scanning glass contains dirt or dust during the white balance procedure, the dusty areas will be overcompensated by the white balance. As soon as the dust disappears the scanner will show streaks in the image along the scanning direction, which show content that is brighter than it should be. If the dust moves to a different location this location will show streaks in the image with content that is darker than it should be. During the white balance procedure, the scanner will scan the test target at different locations to average out the imperfections the test target might still have. It will then calculate a compensation function which will be applied to further scans until either the white balance data is deleted or overwritten by a new white balance.

Begin Process White Balance Step Action 1 Login as Poweruser or Admin, tap on Adjustments in the Adjustments & Support section. 2 Tap on White Balance in the White Balance Adjustments section. WideTEK flatbed scanners: Follow the instructions. Align the white balance with the back of 3a the scanning area. A separate white balance has to be run without the target in case a backlight unit is installed. WideTEK sheet feed scanners: Follow the instructions. Insert the target center aligned into 3b the scanner. Remove paper guides and make sure the target does not get caught. 4 Tap on Next Step and wait up to 40 seconds depending on scanner an number of cameras. If you see a screen like the following the white balance procedure was completed successfully.

If something is wrong the values will turn red. None of the values are stored if any of the values are red. Repeat the whole procedure after the following actions: ➢ ➢ ➢ ➢

Check whether scanning glasses and lamps are clean. Check the test target for any imperfections. Try a different test target if available. Move the test target slightly and make sure it covers all area across the width of the scanner.

If problem persist be prepared to send a screen shot to our support department. 5 Tap on User Logout to end the procedure. End Process White Balance

Service Manual WideTEK Scanners

Page 19 of 133

6.4. Brightness Correction The scanner is calibrated in a way, that if scanning the white balance target the RGB values will be around 240, 240 240. This is close to the saturation point which is at 255, 255, 255. Because the white balance target is of high quality and very white, you may never get saturated white again form normal targets. This might be desirable if photometrical correct images are expected if working under the FADGI or Metamorphoze guidelines but normally this is not desired. Typically someone would expect the background of a normal CAD drawing to turn out completely white especially if the images are printed out. The function Brightness Correction in the White Balance Adjustment section can be used to correct the overall brightness of the scanner independent of the brightness setting in the user controls. ➢ A positive brightness correction factor amplifies the signal. The scan of an average white becomes brighter essentially shifting it towards saturation. ➢ A negative brightness correction factor attenuates the signal. The scan of an average white becomes darker essentially shifting it away from saturation. ➢ Most scanners are preset for a positive value of 0,7dB. This is equivalent to a factor of 108,5% or an 8,5% increase in amplification. ➢ The limit is +2dB and – 2dB which is equivalent of +126% and 80%. Begin Process Brightness Correction Step Action 1 Login as Poweruser or Admin, tap on Adjustments in the Adjustments & Support section. 2 Tab on Brightness Correction in the White Balance Adjustments section. 3 Select a value from the drop down list. 4 Tab on User Logout to end the procedure. End Process Brightness Correction

6.5. Delete White Balance Data Sometimes it might become necessary to delete the White Balance Data after a measurement screwed up completely. Indications are: ➢ The WideTEK sheet feed scanner does not take in normal document anymore.

The Scan line 1 and the Scan line 2 have a horizontal overlap of the distance X and a vertical offset of Y. Both offsets can be adjusted via the camera adjustment screws but a slight error will always remain which the mechanical adjustment could not correct. There are reasons for the additional software based stitching offset correction: ➢ The portion of the stitching error which is caused by temperature variations and other mechanical factors can be corrected automatically by the software at run time. For this function to operate correctly it is necessary to adjust the remaining fixed part of the stitching offsets before the auto-stitching function is run on the scanned image. ➢ The Software based fine adjustment of the stitching offset works more precisely than adjusting screws. It also allows averaging values as well as obtaining sub-pixel results. The Stitching Fine Adjust procedure should be performed in the following cases: ➢ Scanner has been cleaned and glass plate has been removed during this process. ➢ Camera box has been adjusted. ➢ Camera box has been removed for cleaning/inspection or replaced. ➢ Timing belts have been disassembled or replaced on flatbed scanners. In these cases the camera adjustment have to be at least rechecked before this procedure is performed.

7.2. Stitching Fine Adjustment The target used for this process is the WT36C-Z-02-A Stitching adjustment target 960x350m. The index –A may change in the future if manufacturing design or processes change. The target basically is a larger graph paper with boxes 10*10mm, markers for 1mm and bold markers for 5mm lines.

Begin Process Stitching Fine Adjustment Step Action 1 Login as Poweruser or Admin, tap on Adjustments in the Adjustments & Support section. 2 Tab on Stitching in the Camera box & Stitching and Adjustments section. WideTEK sheet feed scanners: Place this target precisely horizontal and center aligned on the scanner and let the scanner pull it in. 3 WideTEK flatbed scanners: Place this target precisely vertical in the middle of the scan area and make sure, it covers the complete scan area from the back to the front. Close the lid. 4 Tab on Next Step and wait a couple of seconds. A screen like the following will appear:

Page 22 of 133

The measurement page merges the two images from the cameras together into one image. ➢ On the WideTEK 25 it shows the top stitching area and the bottom stitching area in two different windows. Only the left one can be modified since there are only two cameras. The reason for showing top and bottom results is that they can be averaged in case there are slight differences. The goal is to get the two images merged together as good as possible. ➢ On the WideTEK36 it shows one stitching area in each window on the left and the right. Both can be modified independently. The goal is to get the two images in each window merged together as good as possible. ➢ The buttons in the middle Stitching 0, Stitching 1 show the stitching results in various position along the scanning direction.

Tab on Y+, Y-, X+ and X- until the two images overly each other as good as possible. The values of these offsets are stored inside the scanner and will be used to stitch each scan. On the WideTEK sheet feed scanners tab on Stitching 1 , 2, 3, 4 to see different vertical areas 6 and try find the best compromised between all of them. 7 Tab on New Values-for a new scan with the latest x- and y-offsets applied. 8 Tab on User Logout to end the procedure. End Process Stitching Fine Adjustment 5

To avoid that you adjust the stitching point incorrectly in the horizontal position (f.e. 6 lines instead of five lines between the bold ones) you can use the blue ruler on top of the windows. The can be shifted horizontally via the left mouse button.

There are two types of flatbed scanners, one is CIS based and the second is CCD based. The CIS models are low cost but lack depth of focus, limiting good scanning quality to flat documents which are pressed against the glass plate. Image Access only builds CCD based flatbed scanners which have a wide depth of focus, are faster than CIS models and have a wider color gamut. The following diagram shows the optical system of the flatbed scanners as a schematic from a side view. Scan glass

Schematic View of a Flatbed Scanner Optical System

The object to be scanned lays on top of the scanning glass. All optical parts below the scanning glass are assembled in a camera box which can be moved horizontally. The object is illuminated with white LEDs and the light of these LEDs is focused by the lenses to produce a small but bright white line. The lenses also carry a diffusor to avoid stripes and banding in the image due to the intensity change across the length of the lamps. The image is projected through a mirror (actually, four mirror surfaces) and through a reduction lens to the trilinear CCD element having 7500 red, 7500 green and 7500 blue sensitive pixels. The CCD’s analog signals are amplified, black and white points are corrected and digitized to produce 48bit color data (36bit on older models). The digital data is then sent via USB3.0 port directly to the main computer. Older scanners used a flat ribbon cable and a frame grabber.

There are two types of large format sheet feed scanners, one type is CIS based and the second one is CCD based. Image Access builds large format sheet feed scanners of both types. In general terms the two different technologies have the following pros and cons. Parameter Depth of focus Speed Color quality Dimensions Price

CCD based

CIS based

Large Fastest Best Normal Higher

Very small Slower Good Compact Lower

The method of using color filters in CCD cameras is also more precise and accurate than the illumination with different colored LEDs in a CIS scanner, resulting in better color quality with the CCD scanner technique. The following diagram shows the principle of the CCD based sheet feed scanner from a side view. The drawing shows the side view of a sheet feed scanner like the WideTEK 36/48.

8.3. CCD Camera Stitching It is crucial to understand the stitching constraints of the CCD technology and their adjustments. The following is a front view of two CCD cameras which overlap for a small distance. The blue and green scan lines are viewed from the top and represent what the cameras actually see. CCD sensor 2

CCD sensor 1

Reduction lens

Scan Line 2

Y

Scan Line 1

X

The Scan line 1 and the Scan line 2 have a horizontal overlay of the distance X and a vertical offset of Y. Both offsets can be adjusted via the camera adjustment screws, but they vary slightly. This is caused by temperature change, after moving the scanner and many more minor factors. X-Offset: The X-offset exists by design and it´s nominal value is 150 pixels. The distance between CCD sensor 1 and CCD sensor 2 is exactly 12 inches . At 600dpi, this leads to a 7200 pixel wide scan line. Since the CCDs used have 7500 pixels across, 150 pixels remain for the overlap on each side. The nominal position of the take-over point is in the middle of X at the pixel position 75. This value can deviate typically by +- 5-10 pixels and as long as it is below 16 pixels, it can be corrected automatically by the software at run time through the patented stitching markers on the upper side of the glass plate. Y-Offset: The Y-offset is very small, the upper drawing is not to scale. The Y-offset is typically in the range of +3-6 pixels and as long as it is below 16 pixels it can be corrected automatically by the software at run time through the patented stitching markers on the upper side of the glass plate.

Service Manual WideTEK Scanners

➢ X and Y stitching offsets of a CCD scanner are adjustable by a technician via adjustment screws inside the camera housings. This is not really simple to do and it is mandatory to read the detailed explanation before performing this task. ➢ Stitching offsets typically do not need to be adjusted again unless the camera modules are exchanged or the scanner experiences rough mechanical impacts i.e. due to mishandling in transport. ➢ The slight variations caused by temperature shifts and other factors are compensated for automatically before each scan, using the stitching markers embossed on the top of the scanning glass.

The image below has a large x-stitching error and a smaller y- stitching error. In order to obtain the image below, a WideTEK 36 has been misadjusted and the automatic stitching compensation was disabled.

CIS modules are very compact and include LEDs, lens and sensor in one package. The main difference is that instead of white light illumination and the object and its image being projected in parallel to individual red, green and blue sensitive CCD elements; the image is projected on one CCD element which is responsive to all colors. In a CIS scanner three exposures (red, green and blue) have to be combined to form a color scan line. Because this is a sequential process, the scanning speed in color usually is only 1/3 of the speed in grayscale. The method of color filters being used in CCD cameras is also more precise and accurate than the illumination with different LED colors, resulting in better color quality with the CCD scanner technique.

CCD chip, one photosensitive element Selfoc lens RGB LEDs Object to be scanned

Cover glass

Schematic View of a Sheet Feed Scanner CIS based Optical System

The object to be scanned is moved under the cover glass. All of the optical parts above the cover glass are part of the CIS element, which is fixed inside the scanner. The object is illuminated with red, green and blue LEDs in three consecutive exposures, effectively scanning 600*1800dpi per alternating color. The image is projected through a Selfoc ® lens to the CCD element having 7250 sensitive pixels. A Selfoc lens is a 1:1 lens system, therefore the image on the CCD element is precisely the same size as the object. The CCD’s analog signals are amplified, black and white points corrected and digitized to produce 48bit color data (36bit on older models). The digital data of up to four CIS module are then sent to a CIS controller board which collects all data and sends them via USB3.0 port directly to the main computer. Older scanners used a flat ribbon cable and a frame grabber on the main PC.

8.5. CIS Camera Stitching It is crucial to understand the stitching constraints of the CIS technology and their adjustments. The following is a top view of two CIS cameras which a large horizontal and vertical overlap due to the size of the housing. The blue and green scan lines are viewed from the top and represent what the CIS modules can actually see. CIS sensor 1

Scan Line 2

Scan Line 1

X

The Scan line 1 and the Scan line 2 have a horizontal overlay of the distance X and a vertical offset of Y. The total scan line is formed by adding Scan line 1 and Scan line 2 with a switch-over point at ½ X. Both offsets must be adjusted once but since the CIS modules are at fixed positions they do not experience temperature induced variations. ➢ Stitching offsets of a CIS scanner are adjustable by the user in a simple way with the help of an adjustment target ➢ Stitching offsets typically remain unchanged unless CIS modules are exchanged or the scanner experiences rough mechanical impacts due to improper shipping etc.

Theory of Operation, Electrical 9.1. Main Linux board The scanners covered in this service manual have many similarities. All of them have a central ITX board which is essentially a “small form factor PC board” running Linux. Linux and all other firmware comes on a standard 3,5” hard disk connected via the SATA port to the main ITX board. The newer scanners, WT36/48CL, feature an SSD (solid state disk) which resides on the main ITX board.

9.2. Power Supply The scanners are all powered by external power supplies. Most scanners are using a 150W, 24V, 6,25A CEC level IV power supply. The double sided WT36DS scanners have two ITX boards and two power supplies. The WT36/48CLscanners are using a 60W, 19V, 3,25A CEC level IV power supply.

9.3. Touchscreen The ITX board drives a touchscreen having a resolution of 800 * 480 pixels. The WT36DS is an exception since its touch is a simpler graphic controller which is controlled via an I²C bus.

9.4. CCD Cameras Older CCD scanners have cameras which are connected via an LVDS flat ribbon cable and a frame grabber to the main ITX board. The newer CCD scanners have cameras that directly connect to the main ITX board via a standard USB3.0 cable.

9.5. CIS Cameras The CIS scanners have a CIS controller which either controls the older analog CIS modules on the WT36/48C or the newer digital CIS modules on the WT36/48CL as well as their LEDs. The older CIS controller connects to the main ITX board via a LVDS flat ribbon cable and a frame grabber. The newer CIS controller on the WT36/48CL scanners connect to the main board via USB3.0.

9.6. WLAN All scanners feature a 1GB/s LAN port for the connection to the local WLAN. The WT36DS has two gigabit network ports. In addition, the WT36/48 CCD scanners have a built in WIFI access point for Scan2PAD operation.

9.7. Foot Switch Most scanners also have a connector for an external foot switch used as an additional method to start a scan.

9.8. Paper Sensors All sheet feed scanners have one or more paper sensors. Some scanners have three (WT36/48: left, middle, right), some have only two (WT36/48CL: left and middle) and some scanners only have one center aligned sensor.

9.9. Motor All WideTEK scanners have one stepper motor which either moves the camera units under the glass plate (WT12/25) or drive the transport drums which move the document through the sheet feed scanner (WT36xx, WT48xx).

The Poweruser has the highest access rights on the customer side. Since the default password is public knowledge, the customer should change this password to prevent default users from accessing Poweruser functionality.

Admin:

The Admin has all access necessary for a field service engineer. This access is only granted to authorized service providers have successfully completed a service training. This manual is intended for this group of users. The default password for the Admin level consists of the last 6 digits of the MAC address.

Factory:

The factory password is highly confidential and unique on each scanner. Only factory personal at Image Access and OEM manufacturing sites have access to this password. Since it changes daily even a brute force attack on the scanner will only work for a very short time.

11.1. General Description All WideTEK scanners have a Linux computer built in. The Linux is running on an industry standard motherboard such as the ones shown below. The boards are populated with a CPU, RAM and in some cases, an SSD. The QM77 board features a quad core i3 processor and 8GB of memory in addition to an S2N-PCI4 interface board for motors and camera connection. This board is used for the high end scanners. The IMB151 board features a J1900 processor and 8GB of memory. It has less computing power and needs no fan for cooling. This board is used for the slower CL scanners.

The above boards are not available as a blank board. They are always part of a larger assembly which includes processor, memory and other parts. The main controller board is a mini ITX board and will be referenced as ITX board from now on. We suggest you read the next page to understand the importance and usage of the serial numbers but it is not mandatory to continue exchanging the ITX board. You can go directly to the chapter Exchange the ITX Board

Service Manual WideTEK Scanners

11.2. Scanner Serial Numbers All WideTEK scanners have a serial number which can be found on the back of the scanner. The serial number is the key to service, options, RMA and everything else having to do with scanner service. During manufacturing, all data about an individual scanner including test scans, is stored in our database together with the serial number. This enables the service technician and/or support person to access all information about the scanner whether it is information about the parts used at the time of build or the firmware version at the time of build. During the lifetime of the scanner, additional information is stored. This includes any updates to newer versions of the firmware, options which have been purchased later and extended warranty subscriptions. Data in scanner database

The serial number consists of the scanner’s device name i.e., WT36CL600 followed by 12 digits which represent the MAC address of the first network port of the scanner. The MAC address is unique and is Sample serial number fixed to the ITX controller. This device number or serial number is the main identifier of a scanner throughout its entire life cycle. Whenever you need to purchase an option, an extended warranty extension, install a firmware update or if you need to make a service call; the serial number must be provided.

If the ITX board needs to be changed, the scanner loses its identity and will have a different serial number. Although it will power up correctly, a few actions have to be taken to restore it completely. The complete process is described in the next section. During the process you need to login as Admin or Poweruser, the following table contains the default passwords.

Passwords: Factory default, after recovery procedure is executed and after a firmware update Login Default password after firmware update Poweruser Poweruser Admin 8fd6cb (Last 6 digits of serial number)

11.3. Exchange the ITX Board CAUTION

The following pictures show the ITX boards assembled with a CPU and memory. The IMB 151 also shows the SSD mounted to the board. Only the parts as shown below are available as spare parts. The ITX boards are industrial quality and carry parts with extended temperature range and life time and it is therefore very unlikely, that a board actually fails. If it fails for whatever reason, it will not be safe to reuse the CPU or memory on a new board because they might have also been affected. This is the reason why only the complete assembly is available as a spare part.

Begin Process to exchange an ITX board Step Action 1 Remove power completely from the scanner. Make a couple of pictures of the ITX board showing cables and connectors. Make sure you 2 understand the wiring diagram shown later in this manual. 3 Remove all cables from the ITX board. 4 Remove all screws and take the ITX board out. 5 Put the new ITX board in place and fasten all screws. 6 Put all connectors back in place. The scanner can be switched on and should boot up properly. If not, make sure all connectors 7 are in their correct position. Verify against your photos taken earlier and use the wiring diagram if necessary. At this point, the scanner is functional again but since the serial number has changed, a couple of additional actions have to be taken. The following has happened after the exchange of the ITX board: The device name (e.g. WT36CL-600-d050998fd6cb) is automatically generated at every start-up of the scanner. With a new ITX board and a new MAC address installed, the device name changes automatically. This will make all internal passwords invalid because they are encrypted with the device name before they are stored internally. Even the default Admin password is incorrect, therefore you must perform a firmware update which restores the Poweruser and Admin passwords to their defaults. Now you need to report the change of the scanners identity in a Maintenance Report to the factory. If you do not report the change, you will not be able to download the correct versions of firmware updates, option keys and manuals and it will not be possible to create correct hard disk reconstruction updates or RMAs. Report the ITX board exchange via login onto the customer service portal at: 8

https://portal.imageaccess.de/index.php?page=Service_HDDMainboard&lang=en

When you login, you need the old device number near the rating plate of the scanner ➢ In the very unlikely case, that the scanner’s ITX board was already changed and the serial number on the back of the scanner is not updated, you can construct the current serial number yourself by adding the 12 digit MAC address to the device name. WT36CL-600123456123456. The Mac address is found on the network port of the ITX boards. Always use the first LAN port which, on a QM77, is the one toward the center of the board.

Fill in the New Mainboard Information and hit the send button. After about one minute, the server will have prepared a couple of files for you to download. The first two are only needed if the HD or SSD was replaced. HD/SSD image with latest firmware version and old serial number (needed only if HD failed)

HD/SSD image with latest firmware version and new serial number (needed only if HD failed) PDF of the report used for these files including new option keys. File containing the latest firmware

The HDD/Mainboard Maintenance Report summarizes all actions and files generated. It will also list all updated keys for various options which may be default options or were purchased before. The new keys are necessary because the serial number is part of the encryption algorithm of the keys so that they are unique on each scanner.

12.1. General Description All WideTEK scanners have a Linux computer built in. The software is stored either on a hard disk (HD) or on a solid state disk (SSD). A Scan2Net HD contains four sections shown on this diagram.

WT36DS-300 WT36DS-600

WT36ART-600 WT48ART-600

Hard Disk Usage Free space

Scan2Net Linux

Customer Settings

Recovery Partition

Scan2Net Linux is the main operating system. It contains all software needed to operate the scanner and is installed at the time of manufacturing. All information about the parts used, the adjustment values achieved and the initially installed option keys are stored in this segment. At the time of manufacturing and also after a HD/SSD has been replaced and the initial image file has been uploaded, the Recovery Partition is generated. The recovery partition contains a 1 to 1 copy of the Scan2Net Linux and is used to “recover” the system in case the main partition fails. Details will be explained later in this chapter. The Customer Settings contain everything which has been changed, added or modified after the initial production or after the recovery procedure has been executed. The Free Space section is used for various tasks but it is erased each time the system starts.

12.2. Secure File Erasing The free space is used as a temporary storage for scanning jobs, for OCR and for printing jobs. This space is always deleted at power on, therefore no traces are left from previous users. In high security applications, the method of how the erase process is done can be chosen. Go to the section User Settings tap on Secure File Erasing (only available for login levels Poweruser and Admin) and select method from the list:

Service Manual WideTEK Scanners

Page 48 of 133

Documents are cached in job-mode either in the volatile RAM disk or on the hard disk. In this case, the location of the document cache is also relevant. By default, the document cache is located on the RAM disk which is cleared at power on. You can change the location and type of document cache used. In the User Settings section tap on Document Cache and select the Document Cache.

Default setting of document cache

Harddisk (volatile mode): The data will be stored temporarily on the hard disk. The data will be deleted at every reboot of the scanner. Harddisk (persistent mode): The data will be stored permanently on the hard disk. This mode is used in conjunction with applications that open more than one job at the same time. Secure file erasing applies to job lists if Harddisk (persistent mode) only when either their owner or Poweruser deletes the job/s. In this case, jobs are deleted using the chosen erasing method.

12.3. HD/SSD Software Failure The file system and the Linux operating system of a Scan2Net scanner are very robust and forgiving. The file system has the ability to repair itself even if the system loses power during a disk write operation, a condition which will almost certainly corrupt any Windows, Android or MAC OS based computer. Nevertheless, under certain circumstances it might happen that the Scan2Net Linux software on the HD/SSD becomes corrupt. Unexpected power failures, hard power off via the main power switch without previous controlled shut down and other unexpected termination of the operating system may be cause to this kind of failure. Also, any uncontrolled interrupt of a firmware update or other functions which involve writing to the main storage (HD or SSD) are a potential risk to the integrity of the firmware on the HD/SSD. The Scan2Net operating system of every WideTEK® or Bookeye® scanner is Linux and although it happens very rarely, the Linux can be corrupted like any other operating system whether it is a Windows, Android, Mac or any other OS.

Service Manual WideTEK Scanners

Page 49 of 133

If the Linux or other parts of the HD/SSD are corrupted, there is still no need to replace the HD/SSD, at least not before the recovery procedure is executed. This procedure is comparable to the procedures necessary to restore a Windows, Android or Apple OS to a previous state.

Service Manual WideTEK Scanners

Page 50 of 133

In a Scan2Net® scanner, an image of the Scan2Net Linux is stored on the Recovery Partition at certain times. These image storage times are at the time of manufacturing and also at all times when an HD/SSD needed to be replaced. The Recovery Key, shown on the right, is an accessory included with every scanner and can be used to invoke the recovery procedure. The recovery procedure is a simple 11 step process. Recovery key

Begin Recovery Process to Restore a HD/SSD

ATTENTION! Make sure that you know the scanner’s IP address, subnet and gateway valid for the network or have the network administrator available. Step 1 2 3

Action Power down the scanner via the start button. Plug in the recovery key to the connector on the back of the scanner. Power up the scanner via the start button. The recovery procedure starts immediately. It replaces the corrupted content of the Scan2Net Linux partition with the content of the recovery partition. This process takes up about 10 - 15 minutes. At the end, it powers down the scanner.

ATTENTION! Make sure that this process is not interrupted by a hard shut down or power failures. If this process is interrupted, a loss of the recovery partition is possible, making it mandatory to physically replace the HD/SSD.

The following process cannot be influenced by the user. It is not necessary to understand the following description in detail and you can go to step 4. The recovery process sends status messages to the touchscreen, showing you the progress of recovery, step by step. The ## symbols represent ciphers that vary depending on the actual hardware and S2N firmware version. ➢ First, the recovery process initializes the scanner’s hardware components and starts several daemons required to start the restoration of the firmware partition. ➢ Then the recovery process checks the status of the splash screen: Setting Splash screen progress to 30% … Splash is not active. No Update needed. ➢ It sets up a Linux console, sets kernel runtime parameters and initializes the recovery partition: * Setting up Linux console …

* Setting kernel runtime parameters … rc (#####) used greatest stack depth: ##### bytes left INIT Entering runlevel: 5 /sbin/recovery/restore … ➢ It saves operation data:

======================================================

Service Manual WideTEK Scanners

Saving Operation data …. ====================================================== ➢ It creates and mounts a new file system: creating file system on /dev/sda1 … mke2fs #.##.# (Day-Month-Year) mounting /dev/sda1 on /mnt …. ➢ It displays the following warning that the recovery procedure must not be interrupted:

+-------------------------------------------------------------------------------------+ | RESTORING SYSTEM: THIS CAN TAKE UP TO 30 MINUTES. | THE DEVICE WILL SHUTDOWN ITSELF AFTER COMPLETION. | DO _NOT_ TURN OFF POWER DURING THIS PROCESS !!!

| | |

+-------------------------------------------------------------------------------------+ ➢ Then it starts to restore directories: restoring /bin restoring /boot restoring /etc restoring /home restoring /lib restoring /lib64 restoring /media restoring /root restoring /sbin restoring /srv restoring /usr ➢ At this point, patience is required. The restoration of /usr takes at least 10 minutes and can take much longer, depending on the size of /usr as well as on hardware parameters. After the restoration of /usr is completed, recovery proceeds. ➢ It creates several mount points and empty directories und updates the file system table of the main system:

====================================================== Creating several mountpoints and empty directories …. ====================================================== updating main system fstab …. ====================================================== ➢ It updates the boot loader and adds some components:

====================================================== Added s2n * Added safe-s2n Added recovery Added safe-recovery

====================================================== unmounting /dev/sda1

====================================================== ➢ After the partition /dev/sda1 has been restored successfully, recovery starts to restore the next partition:

====================================================== creating file system on /dev/sda2 … mke2fs #.##.# (Day-Month-Year) mounting /dev/sda2 on /mnt … restoring /opt/*

Page 52 of 133

➢ Recovery proceeds in the same way to restore further partitions. ➢ Once all partitions, operation counters and journals are restored, you will be notified that the restoration was successful:

recovery restore completed ➢ At this point, the run level is switched back to 0 and all active daemons and other processes are stopped. After several more status messages the scanner powers down automatically. 4 5 6

Wait until the scanner has powered down. Remove the recovery key from the connector on the back of the scanner. Power up the scanner via the start button.

ATTENTION! After this procedure is done, all network credentials are lost. Most important is that the default IP address is now reset to the factory default 192.168.1.50.

After the recovery procedure is executed, the scanner is in the same condition as it was before the last image was stored in the recovery section. Most likely the recovery partition was created at the time of manufacturing which implies that all Customer Settings are lost. Only the option keys installed at the time of manufacturing are restored from the recovery partition. It is therefore necessary to change the defaults of IP address (192.168.1.50), subnet (255.255.255.0) and gateway (192.168.1.50) to settings required to access the respective network. These settings are most likely the ones the scanner had before the HD/SSD recovery became necessary. Passwords: Default after recovery procedure is executed. Login Poweruser Admin

Reboot the scanner and tap Adjustments in the Adjustments & Support section. 11 Start with White Balance and go through the setup procedure as described in the setup manual. 12 Restore all other settings, templates and option keys purchased after delivery. End Recovery Process to Restore a HD/SSD ➢ If you backed up your settings in the past, you can restore them with the Restore Settings button in the Administrative Settings section. Otherwise you must restore all required settings manually. ➢ Restore Settings is only possible if the backup file originates from the scanner to be restored or from another unit of the same device type and model, and if it was created with the same firmware as is active at the time of restoration. ➢ In case that firmware updates were published after you backed up the settings, two extra steps must be added to the restoration procedure.

Service Manual WideTEK Scanners

ATTENTION! Restore Settings restores user settings and data, authentication and billing data, initialization data of lamps and book cradle and output templates. It does not restore user defined scan templates.

Begin Restore Settings 7 Access the scanner through a web browser at 192.168.1.50. 8 Log on at level Poweruser and change the Network Configuration as required. Log on to the service portal and download both the latest firmware version for this scanner 9 and the firmware version that was active at the time of backup. 10 Return to the scanner at level Poweruser and update the scanner with this firmware. Reboot the scanner, log on at level Poweruser, tap Restore Settings in the Administrative 11 Settings section and upload the backup file. 12 Update the scanner with the latest firmware. Reboot the scanner and tap Adjustments in the Adjustments & Support section. 13 Start with White Balance and go through the setup procedure as described in the setup manual. 14 Restore all other settings, templates and option keys purchased after delivery. End Restore Settings

It is recommended to backup settings and scan templates after every firmware update and after every change of settings or templates.

12.4. HD/SSD Hardware Failure Sometimes it might not be possible to restore the content of the HD/SSD because there is a hardware related problem with the main storage device. If the system is still operable, a variety of test functions are available on the service site of the scanner. Access the scanner via a web browser. Log on as Poweruser. Open the Harddisk Test Suite and go to section Harddisk Analyzer. Begin HD/SSD Analysis Step Action Health status The result is either PASSED or FAILED and is a summary of the detailed S.M.A.R.T data. 1 You will presumably never get the result FAILED, because in this case, it is rather unlikely that you can log on and execute one of the Harddisk Analyzer functions. Show S.M.A.R.T. Data S.M.A.R.T. is an industrial standard monitoring and analyzing tool for HD/SSD. In WideTEK and Bookeye scanners, it monitors several processes while the scanner is running 2 and shows the result of their analysis here. For further information on S.M.A.R.T data in general, see http://www.linuxjournal.com/node/6983/print or https://en.wikipedia.org/wiki/S.M.A.R.T.

Perform Media Check Checking the HD usually takes about 60 to 70 minutes, depending on the storage capacity; checking the SSD takes about 10 to 15 minutes. From various indicators, the tool estimates the probability of a HD/SSD failure. This can help you decide if or when the HD/SSD should be 3 swapped. After this check is finished, it updates the S.M.A.R.T. Data details. For further information on S.M.A.R.T data in general see http://www.linuxjournal.com/node/6983/print or https://en.wikipedia.org/wiki/S.M.A.R.T. End HD/SSD Analysis

If the HD/SSD has to be exchanged, follow these procedures.

12.5. Exchange the HD/SSD CAUTION Never open a scanner without completely disconnecting it from the external power supply. Scanners operate from 24V or 19V external power supplies but higher voltages may exist inside the scanner.

ATTENTION! It is mandatory to replace the defect HD/SSD by the original spare part from Image Access. Only then it is equipped with the correct base system, required to restore your device to a fully functional scanner.

Follow steps 4 to 8.

First boot after HD/SSD exchange shows a screen like this

The following has happened after the exchange of the HD/SSD: ➢ The replacement HD or SSD contains basic firmware but lacks individual settings and functions. A couple of additional actions need to be taken to reestablish device specific functions, settings and default options ➢ The first action is to report the change of the scanners HD/SSD in a Maintenance Report to the support portal. The support portal will create a firmware for the scanner which contains the factory settings and the latest firmware.

13.1. Operation of Paper Sensors Paper sensors in WideTEK sheet feed scanners are used to detect the presence of a document in front of the first set of transport drums. Depending on the scanner type, there are one, two or three sensors present. All positions are triggering the same process, which is to feed the document. The time it takes from sensing a document to the actual start of the transport is controlled via the Transport settings menu of each scanner and it´s default is one second. The following table lists the sensor type and their position for each of the scanners. Scanner

Paper sensors of the type S2N-E-PS3-B can be chained up to four. A flat ribbon cable connects all paper sensors, the last one’s output connects to the main controller. The two sensors are working in parallel which means, if either one of the sensors detects a document, the output will become active. The green status LED will light up if a reflective surface is detected by either of the two sensors.

13.3. Adjust Sensitivity of the Paper Sensor S2N-E-PS3-B The sensitivity of the sensors may need to be adjusted. The following situations might make this step necessary ➢ Very thin or transparent paper does not transport at all or scan is interrupted. The sensitivity of the sensors is too low. ➢ Scanner sometimes tries to pull in a document although no document is present. This can be caused by the ambient light level being too high. The sensors are especially sensitive to infrared light caused by daylight. Try shielding the scanner from daylight (using blinds) or reduce the sensor’s sensitivity.

As with any other adjustment, first make sure that the sensors, the surrounding area and the opposite area are clean. Put the proper white calibration target into the scanner so that the sensors will see the bold black bar on the white calibration sheet. The scanner might pull in the target but it will be returned to its original position.

Turn the Sensitivity Control clockwise another 1/8th of a turn (1). This will add more sensitivity to allow onion skin transparent paper and other extreme document material to be detected. If you have document that is not working properly, use that document to make this adjustment

Repeat this for all sensors in the scanner.

The newer WT36-600 and WT48-600 have black painting around the holes in the lower sheet metal. This allows much higher sensitivity therefore a ¼ to ½ turn can be added.

The sensor’s empty reading must be below the marked line (not present in the left diagram) or below the value of 25, whichever is lower. The sensitivity of the sensors is adjusted during the white balance procedure. At this time the empty readings, plus an offset of 3, will be the new threshold. The sensitivity of the sensors may need to be adjusted. The following situations might make this step necessary ➢ Very thin or transparent paper does not transport at all or scan is interrupted. ➢ After warming up or cooling down or after a longer transport, the sensors falsely detect paper or do not detect paper any more. As with any other adjustment, first make sure that the sensors, the surrounding area and the opposite area are clean. Put the proper white calibration target into the scanner and perform a white balance. This will also calibrate the sensors.

This is the normal condition of a paper sensor. The reflective paper sensor consists of an infrared sender and an infrared receiver. The sender emits IR light continuously through a hole in the upper sheet metal. The lower sheet metal also has a hole, which is larger than the beam size. If the beam is not reflected, no paper is detected. If an object (paper, mylar, transparencies, sepias etc.) blocks the hole in the upper sheet metal, the beam is partially reflected and the IR receivers will receive a signal. The strength of the signal largely depends on the infrared properties (not the visible light properties) of the object. In the case that the upper and the lower part of the scanner are not aligned correctly, a partial reflection at the edge of the hole can trigger a false detection. ➢ Check mounting position of both sheet metal parts ➢ Check and correct alignment at the hinges In the case that the upper sheet metal and the sensors are not aligned correctly, the partial blocking of the IR beam can prevent detection or lower it´s sensitivity. ➢ Check mounting position of sensors The sensors with a control LED in the middle can be checked by ensuring that the LED is exactly centered to the hole. Some scanners do not have an open hole in the lower sheet metal, but have a piece of black plastic covering the hole. The plastic is not reflective for IR light, but excessive dust may cause some false detection. ➢ Check and clean the plastic cover of the lower hole

Schematic view of camera unit

The main axis of the optical path starts at the position marked as Scan line. The track length of the camera is approximately 450mm long and is named Light path object side in the above drawing. The light from the object first passes the Protective glass, which is sealed and ensures protection against dust and other environmental effects. The light is then reflected by the fixed Mirror 2 toward Mirror 3, which is the only adjustable mirror. There are three adjustment screws named A, B and C. The three screws named Resolution adjust are used to adjust the total track length of the camera box which defines the resolution. Adjusting the track length is necessary to compensate for mounting position tolerances, focal length tolerances of the lens, thickness and mounting tolerances of the mirrors and tolerances of the main case of the camera box. Mirror 3 reflects the light toward Mirror 2 again, effectively compensating some of the tolerances of the angles of mounting the mirrors. The light beam is reflected through Mirror 3 into the lens. Mirror 3 is also fixed to the main frame of the camera box. The lens is a custom-made part designed exclusively for Image Access. After passing through the lens, the light travels along the distance Light pass image side and hits the CCD. The CCD is mounted on a bracket which can be slightly tilted via the two Skew adjustment screws. These compensate for small skew angles introduced by mounting tolerances. Proprietary technology of Image Access finally converts photons to digital data with a resolution of 48 bits (RGB), which will be sent to the computer via USB 3.0 and be processed in the computer at a later stage to form the required images.

The flatbed scanner design is simple but very reliable. Instead of multiple mirrors which move under the glass plate, the WideTEK flatbed scanners move the complete camera assembly, including the lights, under the glass plate. This not only makes the design simple, it also reduces potential maintenance efforts to a minimum. Basically, the hermetically sealed camera box runs back and forth under the glass plate.

The glass plate has some invisible but important features printed on the bottom. They are hidden under the upper and lower horizontal black bars and are called stitching markers. With these markers, it is possible to determine the y-position which is the position in the direction of movement of the camera box. It is also possible to measure the x-position, the resolution and in case of a multiple camera system, the relative overlap of the two cameras. At power on, the scanner will search for the stitching markers in the back and determine the correct starting position. The starting position found via the stitching markers is a couple of milimeters away from the end position switch at the far back of the scanner. This position can change due to thermal expansion and other small movements of mirrors, driving belts position switches and the like. This is automatically compensated for by the Auto Measurement routine which is invoked at power on and in intervals of a couple of minutes if the scanner is idle. After power on, these intervals are shorter and when the scanner is on for a longer period of time, the intervals become longer. ➢ Every couple of minutes the Auto Measurement function will correct the vertical position (yoffset) of the camera system automatically. ➢ During this measurement, the lamps are switched on and the scanner might move slightly. ➢ This function must be disabled when adjusting the cameras.

14.2. Optical Adjustment of Camera Unit Sometimes, it may become necessary to adjust the camera assembly in the field. This is a very delicate process and there is no safe way back if the process is not performed in the proper way. Therefore, you should not start if you have not fully understood the content of this chapter. Also, each of these settings has a slight influence on the other settings. If you are not experienced, write down all values of a given camera before you start the adjustment process. This is especially important if you must go through more than the camera y-offset adjustment. After each adjustment, check the other settings and correct if necessary. Always try to work in as small as possible increments. The following procedure starts with adjusting the y-offset. This is the offset in the scanning direction. If the glass plate shifts to the front or back, it will influence the y-offset. However, each power on cycle will measure this values and will compensate internally for these shifts. The only remaining yoffset which needs attention is the difference between two cameras and this is described in the following chapter. The WT25 (shown here) has two cameras and the WT12 has only one camera. Cameras are numbered, starting at the left side (viewed from the front of the scanner) with number one.

Action Open the cover of the scanner to get access to the back of the camera unit. Use a hexagon head ball screwdriver, size 3 mm to access the adjustment screws. Avoid pushing against the adjustment screws since this can have an unwanted effect on the measurement. Login as Admin, tap on Adjustments in the Adjustments & Support section. Tab on Auto Measurement off to stop the automatic y-offset correction described in the chapter Mechanical Design of the WT12, WT25. Tab on Fix Camera Box to move the camera box to its fixed position which was used for the initial factory adjustment. Tab on Camera Box Adjustment and wait a couple of seconds.

A window like the one on the right will appear. The blue boxes represent the tolerance fields for the adjustment. The position of the red crosshairs represents the current position of the left or right side of the camera´s view. If the crosshair is inside the blue box, the scanner can compensate for the remaining offsets automatically. It is still best if the crosshair is as close as possible to the center for the maximum safety margin.

ATTENTION! These measurements are done using the stitching markers printed on the glass plate. It is important that the scanning glass plate is in its correct position. If you are not sure, push the glass plate all the way to the back.

A camera might also experience some skew. Skew means that the measured left and right end of the CCD line is not perfectly horizontal. The CCD bracket is mounted on three screws; one is fixed on a washer and not service accessible in the center, the other two allow a slight skew to be applied to the bracket. You should only attempt to adjust the skew in the field if the difference is +-5 or more.

14.4. Troubleshooting “The Last Chance” If all attempts adjusting the camera assembly failed, the camera assembly must be replaced and the misaligned camera must be returned to the factory or the next service center. There is one more chance to adjust the camera assembly in the field but this only the last chance. There is also no guarantee for success. Begin Process “The Last Chance” Step Action Carefully tighten (clockwise) screws A, B and C to the point where you feel a resistance. 1 Perform one turn per screw only and go to the next one. If all screws are at their end position, go to the next step. 2 Untighten all screws by one full turn. Carefully untighten (counterclockwise) screws A, B and C one by one. Turn each screw only by 3 ¼ turn and make sure that they are completely in sync. At each new position, a search with screw A should be performed. Turn screw A clockwise in ¼ increments twice and go back to the starting point by turning it counterclockwise by ½. Try 4 the other direction by turning screw A counterclockwise in ¼ increments twice and go back to the starting point by turning it clockwise by ½ turn. Carefully repeat steps 3 and 4 until a valid readout is shown or until the maximum amount of 5 cycles has expired. The maximum amount of cycles is 10 cycles. At some point, the first valid measurements will appear. At this point continue with the 6 procedures described at the beginning of this chapter. End Process “The Last Chance”

Troubleshooting “The Last Chance” If all attempts adjusting the camera assembly failed, the camera assembly must be replaced and the misaligned camera must be returned to the factory or the next service center. There is one more chance to adjust the camera assembly in the field but this only the last chance. There is also no guarantee for success. Begin Process “The Last Chance” Step Action Carefully tighten (clockwise) screws A, B and C to the point where you feel a resistance. 1 Perform one turn per screw only and go to the next one. If all screws are at their end position, go to the next step. 2 Untighten all screws by one full turn. Carefully untighten (counterclockwise) screws A, B and C one by one. Turn each screw only by 3 ¼ turn and make sure that they are completely in sync. At each new position, a search with screw A should be performed. Turn screw A clockwise in ¼ increments twice and go back to the starting point by turning it counterclockwise by ½. Try 4 the other direction by turning screw A counterclockwise in ¼ increments twice and go back to the starting point by turning it clockwise by ½ turn. Carefully repeat steps 3 and 4 until a valid readout is shown or until the maximum amount of 5 cycles has expired. The maximum amount of cycles is 10 cycles. At some point, the first valid measurements will appear. At this point continue with the 6 procedures described at the beginning of this chapter. End Process “The Last Chance”

16.1. Optical Adjustment of CIS Module Necessary tools: Hex key size 1.5 and 2.5, hex key wrench 2.0 mm. In very rare cases, it may be necessary to adjust the CIS module in the field. This is always mandatory after the replacement of a CIS module or its FCC cable. The WT36CL (shown here) has three CIS modules, the WT48CL is equipped with four CIS modules. CIS modules are numbered, starting at the left side (viewed from the front) with number one. CIS 1

CIS 2

CIS 3

Remove the cover of the scanner upper unit and put it into service position to get access to the CIS modules.

Begin Process to Adjust a CIS Module Step Action 1 Access the scanner via web browser and log on with user name and password Poweruser. 2 Tap on Adjustments in the Adjustments & Support section. Insert the white balance test target WT36C-Z-01-A and follow the white balance process 3 described in the chapter White Balance. Remove the white balance test target. The scanner is now in proper condition to adjust the 4 sharpness of the CIS modules. 5 Return to the web browser and log off from user level Poweruser. Start the adjustment tool at http:\\ScannerIP\Scope.html, i.e. as per default 6 http:\\192.168.1.50\Scope.html.

Service Manual WideTEK Scanners

Page 86 of 133

Start screen of the adjustment tool Scope. Tap Start to begin the measurement. Insert a clean CSTT test target at the position of the replaced CIS module.

Move the CSTT test target using the transport arrows on the touch panel until the line pairs and black triangles around the CSTT test target are right beneath the CIS module. You will then see a pattern like the pattern shown here.

Find the adjusting screws of the respective CIS module, 4 screws for each module, shown on the example of CIS module 2. One screw sits in the center of each mounting bracket. Two screws sit close to the middle of the module. Start with the two outer screws. It does not matter which of the two you adjust first. Tighten the screw clockwise in half turns until you see the respective lines increase. In the example, the left screw has been adjusted first. Should the CIS module be fastened too tight, it may be necessary to loosen the module a little bit to allow adjustment.

Some components of the scanner can be replaced in the field. Although the process is described in detail and pictures also assist in doing everything correctly, it is always a good idea to take a couple of pictures with your smart phone before you start to dismantle parts of the scanner. This is especially important if electrical parts with cables and connectors are exchanged.

ATTENTION! To prevent electric shock and other potential damage, make sure that the scanner is switched OFF and unplugged before opening the scanner. Necessary tools: Hexagon head ball screwdriver, size 2, 3 and 4 mm, also called Allen wrench.

17.1. Open Scanner Upper Unit When you open the scanner upper unit, you will have access to the touchscreen, the power on button, the motor and timing belt, the transport drums and the camera assembly.

Remove all screws from the scanning glass holder and take the holder out. Be careful not to touch the scanning glass.

Remove all screws in the back of the scanner to get the cover off.

Lift the cover up in the back and pull the front slightly out to release the cover

Turn the cover upside down and get full access to touchscreen, touch controller, power on unit and exciter/speakers.

Service Manual WideTEK Scanners

17.2. Open Scanner Lower Unit Front Access When you open the scanner lower unit in the front, you will have access to the computer, the hard disk, the fan and almost all connectors.

Remove the screws from the side covers on the left and right. Remove the side covers.

Loosen screws under the front bench but do not remove them completely. Remove all screws from the paper guide bracket.

Take it completely out. Now you have full access to the computer, the HD and most of the cables and connectors.

17.3. Open Scanner Lower Unit Back Access When you open the scanner lower unit in the front, you will have access to the connectors on the back, the power switch and additional cables.

Remove screws in the back on the left and right side of the rear paper guide.

Remove the screws on top of the rear paper guide. Lift the paper guide and pull it out to the front.

17.4. Exchange Transport Drums Necessary tools: Hexagon head ball screwdriver, size 1,5 mm. Jaw wrench 7mm. Usually, it is only necessary to clean the transport drums. However, it may be necessary to exchange them if they have been exposed to certain aggressive chemicals over an extended period of time. The WideTEK 36 and 48 have four transport drums of which 2 are connected via a mechanical coupler.

Loosen the screws of the coupler and the timing pulley.

Loosen the screws which hold the Lshaped brackets with the bearing for the drums. Do not remove them. The brackets can slide to the side, providing enough room to remove the drums. Do not remove screw circled in red. This serves as a stopper for the L-shaped bracket with the bearing and will define the final position if drums are exchanged. Also, please ensure that the front edge aligns perfectly with the cross beam.

17.5. Troubleshooting Noisy

Transport

It has been observed that sometimes the transport drums can produce a high pitched noise during operation. In this case the bearings of the drum on the motor side will need some WD40 oil or other lubricant suitable for a gliding bearing. In all documented cases of this noise, the cause was on the motor side, nevertheless apply oil on all other bearings if problem persist.

Service Manual WideTEK Scanners

Page 91 of 133

17.6. Exchange Motor and Timing Belt Necessary tools: Hexagon head ball screwdriver, size 2,5 mm. The motors are extremely robust and almost never fail. This is due to the quality of the motor as well as the fact, that our electronics drive the motors with controlled torque already avoiding overload on the electrical side. If there is a problem with the drive train, it is most likely the timing belt. This might be worn out or it has simply lost tension.

Disconnect cable. Remove both screws and replace motor.

To adjust the timing belt tension, first loosen the screw in the slot hole. Push the motor out until tension builds up. The correct tension is reached if you can bend down the timing belt only a few mm or 1/10 of an inch.

Service Manual WideTEK Scanners

Page 92 of 133

17.7. Exchange Background Drum Necessary tools: Hexagon head ball screwdriver, size 3 and 4 mm, ring wrench size 8, pliers The background drums have bearings at their end. Make sure not to lose them when exchanging the drums.

Starting in early 2017, a newer version will have a bore ring on each end to secure the bearings.

17.8. Adjust Background Drum The background drum (2) is pressed against two ball bearings (1) which hold the background drum down. These ball bearings can be adjusted to allow the background drum to form a slit between the drum and the scanning glass.

To adjust it, you should fold a letter size or A4 sheet of normal bond paper (80g/m²) twice along its long edge and place three of these folded pieces of paper along the background drum. Essentially, they will keep a distance between the scanning glass and the drum of approximately four times the thickness. The pictures to the right show the mounting screws for the ball bearings.

After closing the scanner, adjust the position of the ball bearings in a way that they sit on the background drum. Make sure they are not touching any part of the sheet metal or each other.

17.9. Exchange and Reseat Compensator Necessary tools: Hexagon head ball screwdriver, size 2,5mm

Service Manual WideTEK Scanners

Page 93 of 133

Older WT36 and WT48 scanners with chassis versions A or B have compensators which are located over a spring plunger with a ball. They are held in place with two rubber grommets. If they are moved towards the sides, the compensator can easily be replaced. When a new one is installed move it to the spring plunger and make sure that the grommets are at their intended position. The WT6 and 48 of chassis C and higher are built with a different compensator. These compensators are directly screwed onto the paper guide and therefore have a fixed position. If they need to be dismantled, it should be ensured that they are centered in respect to the opening for the ball bearings before the screw is tightened.

Service Manual WideTEK Scanners

17.10.

Exchange Camera Box

Necessary tools: Hexagon head ball screwdriver, size 2,5 and 3 mm The camera box in the WT36 and 48 chassis A and B scanners are different from the ones in chassis C and higher. From a service point of view , the difference is in the connectors, therefore they are not interchangeable. The chassis A and B cameras boxes have dedicated lamp connectors (1) and (2) and a 16pin flat ribbon cable (3) per camera. The WT36 has three flat ribbon cables and the WT48 has four cables. The camera box is mounted to the side walls with two screws on either side. The standoffs and the spacers are not part of a replacement camera therefore they must be taken from the broken camera. The chassis C and higher cameras boxes have a dedicated power connector in the form of a 2,5mm DC jack and one fixed USB3.0 cable per camera. The WT36 has three USB3.0 cables and the WT48 has four USB3.0 cables. The camera box is mounted to the side walls with two screws on either side. The stand-offs and the spacers are not part of a replacement camera therefore they must be taken from the broken camera. First disconnect the white power cable. The USB 3.0 cables are attached to the cameras permanently. Remove all cable straps and take the USB 3.0 cables out before removing the camera. To access the cables the side parts and the paper guide must be removed.

Service Manual WideTEK Scanners

Page 95 of 133

Because there is some play in the mounting of the camera box and the replacement camera box might be adjusted slightly differently, a check of the correct Camera Box Adjustment must be performed in any case. For details about the process, refer to the chapter Camera Optical Adjustment WT36 - WT48 Sheet Feed Scanner. The following is the description of the check procedure as well as the process to relocate the camera box as a whole in an attempt to avoid readjusting the mirrors.

Begin Process to Adjust Camera Mounting Position Login as Admin, tap on Adjustments in the Adjustments & Support section, tap on Camera 1 Box Adjustment in the Camera Box & Stitching Adjustments section. A window like the one on the right will appear: The blue boxes represent the tolerance fields for the adjustment. The position of the red crosshairs represents the current position of the left or right side of the camera´s view. As long as the crosshair is inside the blue box, the scanner can compensate for the remaining offsets automatically. It is still best if the crosshair is as close as possible to the center for the maximum safety margin.

ATTENTION! These measurements are done using the stitching markers printed on the glass plate. It is important that the scanning glass is clean and no parts are inside the paper path. The background drums must also be clean in order to avoid incorrect measurements. If all crosshairs seem to be shifted in one direction (up or down), the camera has shifted as a whole, relative to the stitching markers on the glass plate.

Untighten the four camera mounting screws on the sides of the camera assembly. Move the camera box either to the front or the back until the crosshairs are close to the center. If, after 2 shifting the camera assembly, the crosshair positions are in a range of +- 3, no further action should be taken. End Process to Adjust Camera Mounting Position

18.2. Replace a CIS Module Necessary tools: Hex key 2.5 mm, hex key wrench 2.0 mm Begin Process to Replace a CIS Module 1 Open the upper unit and put it into service position. Open the upper drive unit at an angle of about 45°. Remove the 9 hexagon socket head screws (2.0 mm) which fix the scan glass rack to the upper unit main carrier bracket. Position of screws

Service Manual WideTEK Scanners

Page 99 of 133

Take off the scan glass rack.

Identify the CIS module to be replaced. Find the mounting brackets of this module.

Position of CIS mounting brackets

Take the FCC cable (CIS 2 in the example pictures) out of the plastic clip. Remove the 2 hexagon socket head screws (2.5 mm) from the right CIS mounting bracket. Leave the mounting bracket in place. Just loosen the 2 hexagon socket head screws (2.5 mm) from the left CIS mounting bracket. Release the CIS module from its mounting brackets.

Each bracket holds the two mating parts of the CIS module tight only if the screws are fastened, so that the module comes out easily. The FCC cable is long enough to let the CIS module lay on the paper guide sheet metal.

Open the plastic clamp to take the FCC cable out of the socket.

2 3 4

Replace the CIS module, put the FCC cable into the socket and secure it with the plastic clamp. Make sure that the clamp sits tight. Carefully pull the FCC cable back into the upper unit main carrier bracket and fasten the 4 hexagon socket head screws to hold the CIS module in place. Leave a bit of play to allow sharpness adjustment later. Slide the FCC cable back into the plastic clip.

Service Manual WideTEK Scanners

Page 100 of 133

Before you install the scan glass rack, make sure that the both the CIS module and the scan 5 glass rack are clean and free of dust. Put the scan glass plate back in place and fix it with all 9 hexagon socket head screws. 6 Leave the upper unit open and proceed with the camera adjustment. End Process to Replace a CIS Module

18.3. Adjust Upper and Lower Part Necessary tools: Hex key, size 4. After heavy mishandling in shipping and other transportation, it has been observed that the upper and lower parts are no longer aligned. This can lead to document skew, noise during scanning and other undesirable effects. ➢ Check whether the sides of the upper and the lower part are flush. ➢ Check whether the slit between the upper part and the lower parts is even from the front to the back of the unit. If any of the conditions listed are met, the problem can be fixed via the hinges and the double ball catches that hold the scanner closed.

Begin Process to Adjust Upper and Lower Unit 1 Remove the caps from the hinges. 2 Loosen the screws of the hinges slightly. Shift the upper part to the right and left until the ball bearings are centered with the 3 transport drums.

4

Tighten the screws of the hinges again. It is not required to adjust the gap between upper unit and base unit. During step 1 through 4 5 the pneumatic springs automatically hold both units in correct position. Finally, check if the double ball catches snap in properly. If this is not the case, loosen the screws which fix the catches in the base unit. The screws sit in oblong holes which allow 6 adjusting the position of the catch. The easiest way to adjust the catches is to close the upper unit. This brings the catch into proper position. Fasten the screws again. 7 Afterwards put the caps back in place.
