Last Updated: 03-Jul-2003

Minimum skill level: 3

NOTE: Only a case specialist will predict camera parts.

The stitching procedure has failed (the processor is having problems detecting one and only one image of the stitching wire in the scanned input), and is displayed as system error 32-144 on the touch-screen monitor, or by the following scanner LED light sequence on the scanners front panel:

• Diagnostic = Flashing
• Wait = Off
• Ready = Off

Possible causes are a dirty glass plate or one of the cameras is out of adjustment. Follow the steps listed below to determine the actual cause of the failure and to replace the appropriate parts.

Contact center agents (troubleshooting to be performed with customer)

The steps below are designed to achieve remote resolution of the issue. If the troubleshooting steps below appear to resolve the issue, attempt to verify scanner functionality. If the issue persists following the steps below, generate a CSO for service.

WARNING: 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. Apply cleaners to lint-free cloths only.

NOTE: Leave the scanner on when cleaning the scan area. Doing so provides better lighting to view of particles on the glass plate and surrounding areas.

1. Open the scanner cover by placing your fingers just inside the insertion slot and flip the cover upwards to expose the scan area.
2. Remove the guide plate by pressing down on the plate as you pull the left and right sliders towards the scanner's center (until the metal safety buttons on each side, pop up).

3. Use the two handles to lift out the guide plate.
4. Gently wipe the glass plate. Clean the glass with a lint-free cloth and a mild streak-free glass cleaner.
5. Dry the glass completely using a separate clean, dry lint-free cloth (like the one provided with the maintenance kit).
6. Turn the guide plate, which was removed in Step 5, upside down.
7. Clean the white background assembly. Wipe the white metal area with a lint-free cloth and a mild streak-free glass cleaner.

8. Clean the platen rollers. Wipe the rollers with a lint-free cloth and a mild streak-free glass cleaner.

9. Dry the platen and rollers completely using a separate clean, dry lint-free cloth.
10. Re-install the guide plate and attempt to verify scanner functionality (re-perform function that caused error).
11. If no error, the problem has been resolved.
12. If the problem persists, generate a CSO for service (send all required parts as listed below).

CE instructions

If any of the troubleshooting steps listed below solve the problem, attempt to verify functionality. If functionality is verified, no additional parts should be replaced.

1. Verify the scan area has been cleaned as instructed above.
2. Run SCAN Test 6, Test 9, and check the Camera A and B images of the stitching wire (refer to the Adjustment chapter of the Service Manual).
3. The CCD-centering of one of the CCD-Cameras may be out of adjustment so much that the image of the stitching wire falls outside the range where it can be detected by the copier - run SCAN Test 6, Test 9, and check the CCD-centering (refer to the Adjustment chapter of the Service Manual).
4. Perform scanner maintenance (refer to pages 5-13 of the Service Manual).
5. Attempt to verify functionality.
6. If problems persist, replace the main electronics board (refer to pages 4-27 of the Service Manual).
7. Make sure the lock screw for the Vertical Alignment Arm is tight (refer to the Adjustments chapter of the Service Manual).
8. Look for the stitching wire in the middle of the scanner (under the scanning glass) and make sure it is there. Replace the stitching wire if missing/damaged (refer to pages 4-51 of the Service Manual).
9. Attempt to verify functionality. If problems persist, continue with the remaining steps.
10. Verify the camera motor belt is correctly installed and the motor is working (refer to Adjustments chapter of the Service Manual).
11. Replace the Camera motor if faulty (refer to pages 4-17 of the HP Designjet Copier cc800ps Service Manual).
12. Following replacement, verify functionality.

NOTE: If ANY adjustments have been made to either camera A or B, scanner maintenance MUST be done before the scanner can be used.
