Troubleshooting
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

it is necessary to straighten out
the original to prevent it from

Troubleshooting
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 Q1261-60027
Glass Plate - P/N Q1261-60010
White Background Assembly - P/N Q1278-60018
Fan 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 Calibration
Accurate Cleaning (if the scanner is in a very dirty place or it is dirty
itself, then the mirrors should also be cleaned)
Scanner Calibration
Reset 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 Plate
Both 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.
