Image Quality
YN
Make 3, duplex prints of TP 2, cyan solid fill test page (TP 2 to TP 10). Check the prints for
skew, refer to IQS 1 Registration and Skew.
The prints are skewed.
YN
Make 3 copies of TP 2 from the document glass. Check the copies for skew. The
copies are skewed.
YN
Make a copy of TP 2 from the DADH. Check the copies for skew. The copies
are skewed.
YN
No skew is present. Re-define the image quality defect. Refer to IQ 1
Image Quality Entry RAP.
The skew is originating in the DADH. Go to ADJ 5.3 DADH Skew Adjustment.
There is a skew problem originating in the scanner. Perform the following:
• Check that the scan carriage is parallel to edge of the document glass. If neces-
sary, perform ADJ 62.2 Scan Carriage Assembly.
• Check that the scan cables are wrapped around their drive pulleys, refer to
REP 62.7 Scan Cables.
• If necessary, install a new scanner, PL 62.15 Item 1.
The skew occurs in the duplex paper path. Check the following nip and drive rolls, refer to
GP 29 Component Locations:
• Roller drive J - PL 10.10 Item 1.
• Roller drive L - PL 10.10 Item 2.
• Roller nip P - PL 10.15 Item 6.
• Nip R, C and Q takeaway rolls, PL 82.15 Item 10.
• Transport roller drive 2, D, F - PL 82.10 Item 1.
• Transport roller TAR vertical, E - PL 82.10 Item 2.
Clean the rolls, GP 27 or install new components as necessary.
Perform dC969 Clean Ink Smears. Print 3 copies of TP 2, cyan solid fill test page (TP 2 to TP
10). Check the prints for skew, refer to IQS 1 Registration and Skew.
The prints are good.

Go to the 82-507-00, 82-508-00 Nip C and Nip D Release Solenoid Over Cur-
rent RAP.
Check the operation of the air pumps, refer to 88-508-00 Registration/preheat Air
Pump Incorrect Current RAP. If the air pumps are working, then install a new regis
-
tration/preheat assembly, PL 88.10 Item 1.
NOTE: W/TAG 018 machines do not have air pumps install as standard. However,
the preheat air pumps in a replacement registration/preheat assembly will function
when the unit is installed, refer to service bulletin T8009-12-06.
Make 3 prints of TP 2, cyan solid fill test page (TP 2 to TP 10). The prints are good.
YN
Make five prints from each tray and the bypass tray to identify the source of skew.
Perform the following:
• Check the tray feed rolls and guides for contamination.
• Check the tray feed rolls and transport rolls for wear. Install new components as
necessary.
• Check that there is no variation in the size or weight of the sheets of paper in
