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:

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.

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:

Actuator

Media Entry Sensor Ready (Green)

Media Exit Sensor Ready (Green)

Adjustment Slider for Media Thickness Wait (Yellow)

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.

To perform the Camera Adjustment, refer to Chapter 5 - Adjustments of this Service Manual.

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

2.5. When the original has been printed on an Inkjet

printer this option should be

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

scanner setup). A visible

stitching error should not be

confused with the error

message "Error 32 - Could not
