Chapter 2 - System Error Codes 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 refer to Chapter 5 - Adjustments

The purpose of the SCANtest 6 diagnostic software is to support the
troubleshooting and adjustment of the Scanner.

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.

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:

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.

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

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

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

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")

1-26

HP Designjet 4500 Scanner Service Manual

Troubleshooting

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.
