Image Quality RAPs
IQ7 DADH, Document Glass and Scanner RAP
Use this RAP to identify failures caused by the DADH, document glass and the scanner.
Ensure IQ1 Image Quality Entry RAP is performed before starting this RAP.
Procedure
Perform the following:
•
DADH Checkout
•
Document Glass Checkout
•
Scanner Checkout (32-55 ppm)
•
Scanner Checkout (65-87 ppm)
DADH Checkout
Perform the following:
•
Clean the underside of the DADH area around the CVT roll, PL 5.25.
•
Clean the top surface of the CVT glass and the document glass, refer to ADJ 14.1A
Optics Cleaning Procedure (32-55 ppm) or ADJ 14.1B Optics Cleaning Procedure (65-87
ppm).
•
If the documents are skewed. Check that the document input guides are correctly
adjusted.
•
Check that the DADH is seated correctly, perform the ADJ 5.2 DADH Height Adjustment.
•
Make copies from the DADH and the document glass. If the copies from the DADH are
lighter or darker than those from the document glass, perform the following:
–
Go to dC131 NVM Read / Write location 15-007 CVT scanning image gain. The
default value is 3. If the value is increased copies made from the DADH will be
darker. If the value is decreased, copies made from the DADH will be lighter.
•
Make copies from the DADH. If the copies have a background problem, perform the fol-
lowing:
–
Check the DADH height, Refer to ADJ 5.2 DADH Height Adjustment.
–
Check the registration. Refer to dC604 Registration Setup.
–
Copying thick documents can leave the DADH raised above the document glass.
Raise and lower the DADH five times. If the DADH is still raised, install new counter-
balance, PL 5.10 Item 2 and PL 5.10 Item 4.
•
Make copies from the DADH. If the copies are stretched or smudged, perform the follow-
ing:
–
Lower the height of the DADH by half a turn of the setting screws, refer to ADJ 5.2
DADH Height Adjustment. Make copies from the DADH after each adjustment. If the
fault persists, re-adjust the height of the DADH as necessary.
–
If the fault persists after the height of the DADH has been adjusted, install a new
DADH baffle assembly, PL 5.30 Item 5. Re-adjust the height of the DADH to the
default setting, refer to ADJ 5.2 DADH Height Adjustment.
Document Glass Checkout
Perform the following:
•
Clean the top surface of the CVT glass and the document glass, refer to ADJ 14.1A
Optics Cleaning Procedure (32-55 ppm) or ADJ 14.1B Optics Cleaning Procedure (65-87
ppm).
•
Check the position of the document pad, ADJ 5.6 DADH Document Pad.
•
Check that the white AGC strips on the document glass and the CVT glass are at the front
and underside of the glass.
Scanner Checkout (32-55 ppm)
Check the following:
•
Raise the DADH. Make a copy from the document glass. If the exposure lamp does not
illuminate, go to the 14D Exposure Lamp Failure RAP.
•
Check the mirrors and exposure lamp for contamination, go to ADJ 14.1A Optics Clean-
ing Procedure (32-55 ppm).
Scanner Checkout (65-87 ppm)
Perform the following:
•
If the copy of the internal test is fragmented and displaced, check the following:
–
The harness connections from the full width array to the scanner PWB.
–
The harness connections from the scanner PWB to the image processing PWB.
–
If fragmented and displaced images appear in a regular pattern across process
direction, remove and re-seat all EPC memory PWBs.
–
If necessary, go to 03-330, 03-462 Image Processing PWB to Scanner Faults RAP.
•
Raise the DADH. Make a copy from the document glass. If the exposure lamp does not
illuminate, go to the 14-703B to 14-706B, 712B, 714B Failure To Calibrate RAP (65-87
ppm) and perform the Exposure Lamp Check.
•
Check the full width array and exposure lamp for contamination, go to ADJ 14.1B Optics
Cleaning Procedure (65-87 ppm).
