Is the Problem with the Printer or Scanner
If you encounter 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.1 vertical white, black or color line.
If you encounter 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:

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 an LED ON
when pressed.
Key
Forward and Reverse Ready (Green)
Power Wait (Yellow)
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 Test
This test checks the functionality of the Media Sensors and the Media Thickness Detector.
When the test is executed, the following LEDs turn ON when one of the Media Sensors is activated, or when one or both Adjustment Sliders for
Media Thickness are pulled out from Normal position:
Actuator
Media Entry Sensor Ready (Green)
Media Exit Sensor Ready (Green)

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.
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
We recommend that you use Test 27 to adjust the camera because there is a wizard which guides you through the complete process.
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 SM 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/Correction factor …’ option of SW copying. The correction factor is stored in the Flash Memory on the Driver Board.
Test 13: Switch Scanner to Test Mode
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 SM 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 SM 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.
1-6
HP Designjet 4500 Scanner Service Manual
Page 13
Troubleshooting
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
The purpose of this test is to create a file, SCANdump.con, which contains Light Profiles and other scanner data for diagnostics purposes.
When the test is executed, the file SCANdump.con will be placed in the directory c:\Temp\. The files contained in SCANdump.con may be unpacked by SCANview 6 by double clicking on SCANdump.con. The unpacked Light Profiles may be viewed by SCANview 6. If other files are included, use an appropriate reader or viewer.
The files are also placed as a button on the active desktop and is called SCANdump. The files can be stored on a disk and can be sent by e-mail.
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 (whenever possible). See 5-7, Adjusting the Camera Using the Camera Wizard
Test 28: Original Guide Sensor Test
This is to test the Original Guide Sensors which are located under the Top Profile. See 5-27, 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 5-31, 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 5-31, Driver Board Communication Test

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

Preventive Maintenance Kit for HP DesignJet Scanners
The purpose of any scheduled Preventive Maintenance is to prevent any failures in the scanner, ensuring a good performance during the life of the product.
Level of Scanner Usage - Normal usage means the scanner lamp is ON 8
hours per day and 250 days per year. Under normal usage conditions, it will be approximately 2 years before the scanner will need any preventive maintenance. If the scanner is used more than the normal usage conditions, then it will need preventive maintenance much more frequently.
One of the Lamp counters is assigned to counting the number of hours that the Lamp is ON. When the scanner exceeds 4000 hours, the Panel PC will display the message "Maintenance Advised".
Once the Maintenance Advised message is displayed, you must use the Preventive Maintenance Kit to replace the most worn parts of the scanner.
The Preventive Maintenance Kit part number is Q1261-60060 and it consists of the following:
Fluorescent Lamp - P/N Q1261-60027Glass Plate - P/N Q1261-60010White Background Assembly - P/N Q1278-60018Fan Filter - No PN available for HP (not a current Service Part)
After replacing these parts, you will need to perform some procedures to ensure that the scanner functions correctly:
Driver Board CalibrationAccurate Cleaning (if the scanner is in a very dirty place or it is dirty
itself, then the mirrors should also be cleaned)
Scanner CalibrationReset the Lamp Counter
The lamp counter can be reset using the Panel PC. The password that you will be requested in order to reset the counter is "bigcoco".
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):
White Background Plate on the Original Guide PlateBoth sides of the Glass Plate. Be careful not to push 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.
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.
HP Designjet 4500 Scanner Service Manual
1-25
Page 32
Troubleshooting
The Mirrors are normally "Out of Focus" so therefore small dust particles on the Mirrors will NOT deteriorate the scanning result.
The Feed Rollers. These may be cleaned with a damp micro-fibre
cleaning cloth.
Once all these procedures have been completed, the scanner will be ready to work correctly.
Panel PC (Touch Screen) Problems
The following problems are related to the Panel PC and it’s related components.
After Powering ON the System Does Not Start
1 Check to see if the Keyboard Indicator light is turned On:
If No: The system is not properly connected to the Power Supply. Check
for any loose connections.
If Yes: Check if there is a non-bootable Disk in the Floppy Disk Drive.
– Remove the Diskette from the FDD and restart the Panel PC – The Operating System may be suffering from unrecoverable damage.
Perform a recovery using the Recovery CD.
2 If the Panel PC still doesn’t work, then replace the Main Board in the Panel
PC (P/N Q1278-60034).
The System is Unable to Boot from the Hard Disk Drive (HDD)
1 In the BIOS setup select Standard CMOS Features and check if the IDE
detection method is set to AUTO (password to access the BIOS is bigcoco)?
If Yes: In Advanced BIOS features, set HDD to first boot device.If No: Choose auto for all IDE detection.
2 Check if HDD can be detected in the boot-up system configuration table:
If Yes: check the boot up files in HDD, recover it if necessary.If No: replace HDD (P/N Q1278-60032).
The CD-ROM Indicator Light is Off When Powering Up and the Screen Shows no Message of any CD-ROM Installed
1 Check for CD-ROM auto detection in the BIOS setup (password to access the
BIOS is bigcoco):
Select standard CMOS features, set all IDE detections (i.e. Primary
master, Primary slave, secondary master, secondary slave) to AUTO.
2 Reconnect the cable between the CD-ROM and the Main Board
3 First replace the cable, and if that fails, replace the CD-ROM Drive.
The Floppy Disk Drive Indicator Light is Off
1 Check that the type of Floppy Disk Drive (FDD) is correct in the BIOS features
setup (1.44Mb 3.5")

2 Reconnect the cable between the FDD and the Main Board.
3 Make sure the power input to FDD is correctly connected.
4 If the problem continues, replace the FDD (P/N Q1278-60035).
The Touch Screen Function Fails to Work
1 Turn off the system and power on again.
2 The default setting for touch screen is using COM4. Make sure that COM 4
is NOT assigned to any other application.
3 Is the cursor responding at all?
If Yes: This may be due to faulty calibration. Try performing the
calibration program again.
If No: The driver may not have been installed properly. Perform a
recovery using the Recovery CD.
4 If the problem continues, replace the Touch Screen (P/N Q1278-60043)
No Power Output from Power Supply Unit
1 Replace the Power Supply Unit (P/N Q1278-60044)
SDRAM Not Detected and There is a Beeping Sound When Powering On
1 Re-install the SDRAM Memory Module and check if this solves the problem:
If Yes: There was a poor connection between the Main Board and the
SDRAM Memory Module.
If No: Replace the SDRAM Memory Module (P/N Q1278-60042).
The PCA/ISA Bus Card is Not Working
1 Check if the PCA/ISA riser board is installed correctly.
2 If possible, try installing the PCI/ISA bus card in to another computer and
check if it works there:
If Yes: Re-install the PCI/ISA bus card in to the Panel PC.If No: Check the IRQ & IO address setting.
3 Replace the PCI/ISA bus card (P/N Q1278-60048).
The Fan is Not Running When the Panel PC is ON
1 Check if the CPU fan cable is connected properly. Reconnect the cable if
necessary.
2 If possible, try installing the CPU Fan in to another computer and check if it
works there:
If Yes: Re-install the CPU Fan in to the Panel PC.If No: check +12V fan power, if +12V is OK then replace CPU fan.
