Guide to Troubleshooting the HP family of MFPs and
Scanners
This chapter guides you through the various procedures for troubleshooting
the HP family of MFPs and scanners.
Troubleshooting Tips
1First record whether the problem is with the Printer, the Scanner, or the Touch
Screen.
2Make sure that the scanning area is completely clean.
3 Test 20: Noise Test can help you find whether or not the scanning area is
dirty.
4The SCAN dump files can help you to understand the light profile of the
affected scanner.
5Remember, 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 with the scanner?
If you experience one of 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.
If you experience one of the following symptoms, perform an Image Preview
in the scanner and send a Test Print to the printer:
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 of your prints, try the following:
1Print out a file already stored or print out the demo plot.
2Once the print is finished, insert it into the Scanner.
3Once scanned, print out the scanned image.
If the original print is the same as the copied print, then the problem is
related to the Printer.
If the original print is NOT the same as the copied print, then the problem
is related to the Scanner.

message that is displayed.
If the Key test fails, replace thse Right Cover (which contains the Operator
Panel).
Test 4: Original-Sensor Test
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.
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

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
Always use Test 9: Camera adjustment to adjust the
cameras. Do not use Test 27: Camera Adjustment Wizard.

Troubleshooting
HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP Service Manual
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
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

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 only if you do not have experience in
adjusting the camera, otherwise you should always use Test 9. See 5-19,
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 5-28, 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 5-32, 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 5-32, Driver Board Communication Test.
Remember to perform the SCANdump test and provide the
HP Support personnel with the information file stored in the
c:\Temp directory.

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

stitching error should not be
confused with the error

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.
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.
The Cleaning Procedure
When cleaning any part of the scanning area DO NOT use abrasives,
acetone, benzene or fluids that contain these chemicals. Do not spray liquids
directly onto the scanner glass plate or anywhere else in the scanner.
1Turn the scanner power off.
2Disconnect the scanner power cable.
3Open the Guide Plate by pushing down on the left and right locking levers
and flip it upwards to expose the scan area.
The mirrors are normally "Out of Focus", therefore small dust
particles on the mirrors will not deteriorate the scanning
result.

Erase the Parameter Block in the Scanner
The Scanner has a memory block called the Parameter block. The Parameter
block contains the following:
Stitching values camera transition a/b and b/c
Basic calibration information
Level for uncorrected light profile
Corrected light profile
Camera matching, gray
NTSC color space
sRGB color space
Date of the last calibration
The information that is stored in the Parameter block is gathered during the
calibration of the scanner (Scanner Maintenance).
In rare instances, the stored values will vary too greatly from current read
values, which can cause the scanner to report an error. The easiest way to
solve this problem is to erase the Parameter block.
When to Erase the Parameter Block
It is beneficial to erase the parameter block under the following
circumstances:
If the Scanner Maintenance is unable to recognize the calibrating sheet.
If error messages such as the the following appear:
"Unable to correct camera x"
"Unable to stitch camera x/x"
Before changing any hardware, especially before changing the main
board or the camera boards
Before performing any camera adjustments
How to Erase the Parameter Block
All of the information in the Parameter block is restored when the Scanner
Maintenance is run.
