Troubleshooting tips
1. First record whether the problem is with the Printer, the Scanner, or the Touch Screen.
2. Make sure that the scanning area is completely clean.
3. Test 20: Noise Test can help you find where the scanning area is dirty.
4. The SCAN dump files can help you to understand the light profile of the affected scanner.
5. Remember, in order to cancel when copying, press the Cancel button on the Touch Screen and
the Cancel button on the printer.
Is the problem with the Printer or the Scanner?
If you experience the following symptoms, the problem could be related to the scanner:
System Error on the Touch Screen.
LED’s flashing on the Scanner Operator Panel.
WIDEsystem error message.
Vertical lines (either color or black) in the scanned image.
ENWW Troubleshooting tips 1
If you experience the following symptoms, then perform an Image Preview and send a Test Print:
Image Quality Problems.
No Output
Output is not as expected.
If the Image preview fails, this points to a problem with the Scanner. If the Test Print fails, this points to a problem with the Printer.

Image-quality problems

If you have Image Quality problems in any prints, try the following:
1. Print out a file already stored or print out a demo file.
2. Once the print is finished, insert it into the Scanner.
3. Once scanned, print out the scanned image.
If the original print is the same as the copied print, then the problem is associated with the Printer.
If the original print is NOT the same as the copied print, then the problem is associated with the
Scanner.

Output problems

If the output is not as you expected it to be, try the following:
Check all the settings in the Software: Color Settings and Margins.
Check media settings: Media profile (in software) and media loaded in the printer (front panel
selection) should be the same.
Perform Color Calibration (both Scanner and printer).
Check the Preview Image.
If there is no output at all, then try the following:
Check the connection between the Printer and the scanner.
Check the selected settings: List, Collate, Scan to file...

Troubleshooting System Error Codes

Chapter 2, System Error Codes on page 30, contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.

Using the SCANtest 6 Diagnostic Software

Here we briefly describe the various tests found in the SCANtest 6 Diagnostic Software, for more detail of some of the Adjustments shown below see Chapter 5,
on page 158.
The purpose of the SCANtest 6 diagnostic software is to support the troubleshooting and adjustment of the Scanner.
2 Chapter 1 Troubleshooting ENWW
Scanner Adjustments and Calibrations
To access the software you must go to the Setup tab and to: Options, System, Service (this part is password protected, the password is ’support' Scantest.
When the SCANtest 6 diagnostic software has been started, the Scanner is switched ON in Test Mode, and the Diagnostic LED on the Operator Panel is turned ON.
Scanner Test Program Menu
Test 1: Scanner Information
Test 2: LED Test
Test 3: Key Test
Test 4: Original-Sensor Test
Test 5: Lamp Test
Test 6: Motor Test
Test 7: Complete Hardware Test
Test 9: Camera Adjustment
Test 11: Stitching and Vertical Alignment
Test 12: Adjust Y-Axis Scaling
Test 13: Switch Scanner to Test Mode
Test 20: Noise Test
Test 21: Scan Dump
Test 27: Camera Adjustment Wizard
Test 28: Original Guide Sensor Test
Test 30: Calibrate ATAC
Test 31: Driver Board Communication Test
If SCANtest 6 is started when the scanner is in Error Mode, the Error Code Number and a short description of the error will be displayed on the screen.
Test 1: Scanner Information
This test displays general information regarding the scanner. When executed, the test displays the following:

Test 2: LED Test
This test checks the functionality of the LED Indicators on the Operator Panel. When the test is executed, all the LEDs are sequentially switched ON/OFF until Test 2 is terminated. If any of the LEDs fail, you will NOT get an error message, instead the LED will NOT switch ON or OFF. If the LED test fails, replace the Right Cover (which contains the Operator Panel).
Test 3: Key Test
This test checks the functionality of the Keys on the Operator Panel. When the test is executed, each key on the Operator Panel will turn the LED ON when pressed.
Key LED
Forward and Reverse Ready (Green)
Power Wait (Yellow)
ATAC control key
The only way to know if the test fails is by inspection, there is no error message that is displayed.
If the Key test fails, replace the Right Cover (which contains the Operator Panel).
Test 4: Original-Sensor T es t
This test checks the functionality of the Media Sensors.
When the test is executed, the following LEDs turn ON when one of the Media Sensors is activated.
Actuator LED
Media Entry Sensor Ready (Green)
Media Exit Sensor Ready (Green)
To test the Media Sensors, load a Sheet of media (A4) and the Ready LED switches ON and when you remove it the Ready LED switches OFF.
If the test fails (if any of the LEDs fail to switch ON), then the problem will be related to corresponding Sensor.
Test 5: Lamp Test
This test checks the functionality of the Lamp and associated electronics.
When the test is executed, a message on the screen will indicate whether the Lamp is turned ON or OFF (Lamp power is turned ON/OFF) and whether the Light is ON/OFF (Light is detected or not).
The Lamp is delayed for approximately 2 seconds when switched ON.
Test 6: Motor Test
This test checks the functionality of the Stepper Motor and any associated electronics.
When the test is executed, a menu appears that allows you to select the motor speed and the motor direction.
4 Chapter 1 Troubleshooting ENWW
If the Stepper Motor or the Driver Board fails to run when the test is executed, then the Stepper Motor should be replaced.
Test 7: Complete Hardware Test
This test checks the various functions of the Driver and Camera Boards.
Test 9: Camera Adjustment
NOTE: This is the recommended way to adjust the cameras. However, Test 27 (the Camera
Adjustment Wizard) is provided as an easier alternative.
This test contains a Software Oscilloscope that allows you to check and adjust the CCD-Cameras. The following functions can be selected from the Test Program Menu.
Uncorrected or Corrected Light Profile.
Red, Green, or Blue Color Channel.
Special Detail Views for Light Profile, Scan Width, and Vertical Positioning.
Forward / Reverse controls for the Camera Motor.
Save screen images.
Print screen images.
The content of the Detail Views is marked on the upper overview window by red vertical lines. The continuous lines refer to the left Detail View and the dashed lines to the right Detail View.
Test 11: Stitching and Vertical Alignment
This test is also included in the Scanner Maintenance Software.
This test performs Automatic Vertical Alignment and Horizontal Stitching.
Once the test has been started:
Insert Calibration Sheet.
Select Vertical Alignment to align the cameras.
Select Horizontal Stitching to stitch the cameras.
The screen image can be saved or printed.
This test allows manual setting of the Stitch Values. The Stitch Values are stored in the Flash Memory on the Driver Board.
The Vertical Alignment may be adjusted manually by controlling the Camera Motor from the control
field '<< dddd>>'. The two buttons marked ''<<' respectively '>>' are used to start the motor and to
determine the direction of rotation. When started, the motor runs for dddd mili-seconds as entered into the control field.
Test 12: Adjustment of Y-Axis Scaling
This test allows you to adjust the Y-Axis Scaling.
The scaling (dpi) in the mechanical scan direction (Y-Axis) depends on the speed of the stepper motor relative to the scanline Exposure Time. The default motor speed can be changed ± 1%, either from Test
12 or by using the ‘Scanner Setup/Correct ion fa ctor …’ option of SW copying. The correction factor
is stored in the Flash Memory on the Driver Board.
Test 13: Switch Scanner to Test Mode
ENWW Using the SCANtest 6 Diagnostic Software 5
This test allows you to switch the scanner back to Test Mode. Useful if the scanner gets out of Test Mode, e.g. if it has to be turned OFF/ON during troubleshooting.
Test 20: Noise Test
The purpose of this test is to detect and locate the possible cause (dust, dirt, scratches,..) of vertical lines running from top to bottom of the scanned image.
When the test is executed, it scans the White Calibration Area of the Calibration Sheet and displays, for each color channel, the graytone values of each separate pixel averaged over the scanned band.
The displayed image of the Calibration Sheet will be superimposed by low level noise caused by the CCD chip, and larger spikes most likely caused by dust, dirt, scratches, or similar defects on the Glass Plate. In rare cases, larger spikes may be caused by dust, dirt, or pixel faults on the CCD chip.
The positions of larger spikes are shown by the numbers (cm or inch units) opposite to the spikes. The numbers refer to the Sideload-ruler on the scanner. Larger spikes going downwards are often caused by dust, dirt, scratches, or similar defects on the Glass Plate and may be removed by cleaning the Glass Plate. Downward spikes often show up as darker vertical lines in the scanned image.
Larger spikes going upwards are often caused by dust or dirt present on the Glass Plate during the last calibration with Scanner Maintenance. These defects are memorized by the Light Profiles stored in the Flash Memory and can only be removed by cleaning of the Glass Plate followed by running Scanner Maintenance again. Upward spikes show up as very bright vertical lines in the scanned image.
White vertical lines in the scanned image may be found even if Noise Test shows a perfectly ‘clean’ scanner. In this case, the cause may be white dust or particles on the backside of the Glass Plate having the same color as the white background. In this case, the Light Profiles of SCANtest 6, Test 9 may show upwards going spikes when a dark original is placed in the scan area.
Test 21: SCANdump
SCANdump is a tool for remote diagnostic. SCANdump saves the light profile from the cameras, error codes, and statistics.
When the test is executed, the file SCANdump.con will be placed in the directory c:\Temp\.
Test 27: Camera Adjustment Wizard
This allows you to adjust the camera using a wizard that guides you through the complete process. Use this test (instead of Test 9) only if you have no experience in adjusting the camera. See Adjusting the Camera Using the Camera Wizard.
Test 28: Original Guide Sensor Test
This is to test the Guide Plate Sensors which are located under the Guide Plate. See Original Guide Sensor Test.
Test 30: Calibrate ATAC (Automatic Thickness Adjustment Control)
This test sets the current level at which the ATAC will stop if something is preventing it from moving down. See Calibrate ATAC (Automatic Thickness Adjustment Control).
Test 31: Driver Board Communication Test
This test checks the communication between the Scanner and the Driver Board. See Driver Board Communication Test.

What is Ink Printer Original?
What is a visible stitching error?
- - C When the original has been printed on an Inkjet printer this option should be enabled.
- - - C A visible stitching error appears typically as a column of broken lines between 2 cameras. Normally it can be solved by running Scanner Maintenance, which will perform an automatic stitching adjustment. With some curled or creased/crumpled originals it is necessary to straighten out the original to prevent it from lifting from the glass plate. With thick originals it can be necessary to adjust the stitching (stitching used for thick originals only, set this in scanner setup). A visible stitching error should not be confused with the error message Error 32 - Could not stitch Camera A and B.

37 Firmware All of the LEDs in
the scanner’s front panel are flashing when you turn on the scanner (as shown in the image below), indicating that printer firmware needs to be upgraded.
NOTE: This
describes a different situation than when the scanner is turned on in special boot mode, in which the LEDs also flash.
- - - C The most probable reason for this situation is that the last firmware upgrade attempt was not successful. To remedy this situation, upgrade the firmware (see
Firmware on page 186).
NOTE: Before launching the
firmware upgrade utility, verify that the scanner is connected directly to the touchscreen by the FireWire cable, and then press the rescan bus button. The scanner will not detect the necessary connection without the use of the FireWire.

Cleaning the Scanning Area

The following parts must be cleaned using a soft lint-free cloth and a mild, streak-free, cleaning detergent. Alternatively, the parts may be cleaned without the use of cleaning detergents by using a damp micro-fibre cleaning cloth (soak the cloth with water and wring until damp):
Main scanner cover. Clean the main scanner cover to ensure that no dust is introduced into the
scanning area when you scan an original.
White Background Plate on the Guide Plate
The Glass Plate. If you clean both sides, be very careful not to touch the Stitching Wire (located
under the Glass Plate) out of position. Do not use solvents, as this may dissolve the paint used for the black masks on the Glass Plate. Do not recommend that customers clean the underside of the glass plate; it should only be cleaned by an HP support technician.
The Mirrors. It is necessary to remove the Mirror Chassis to get access to the Mirrors for cleaning.
The Camera Adjustment must be checked and if necessary readjusted after the replacement of the Mirror Chassis.
