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.
3Test 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.

HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP Service Manual |
Troubleshooting
No Output or Output is not as expected
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, etc.
Troubleshooting System Error Codes
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.
If you have an error code which is not documented in this Service Manual, or you have an error which you cannot resolve, report the error to the HP Response Center or the nearest HP Support Office. When reporting the error, have the following information ready:
Model and serial number of the MFP or scanner
Software and firmware version for the MFP or scanner. To check the software and firmware version, press the Setup tab, and then select
Options > General > About).
The complete error number
ScanDump of Light Profiles
Make sure you provide the full error code and the full software and firmware version. Without this information, the HP Support personnel cannot help you.
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 -
The purpose of the SCANtest 6 diagnostic software is to support the troubleshooting and adjustment of the Scanner.
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

Troubleshooting
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 |
LED |
|
|
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 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.
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 the associated electronics.
When the test is executed, a message on the Touch 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
HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP Service Manual |
1-5 |
Troubleshooting
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
Always use Test 9: Camera adjustment to adjust the cameras. Do not use Test 27: Camera Adjustment Wizard.
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 Profiles.
Red, Green, or Blue Color Channels.
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
1-6 |
HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP Service Manual |
Troubleshooting
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
HP Designjet T1100 MFP, 4500mfp, 4500 Scanner, 820 MFP Service Manual |
1-7 |
Troubleshooting
directory c:\Temp\.
Remember to perform the SCANdump test and provide the HP Support personnel with the information file stored in the c:\Temp directory.
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.
