Automatic Document Feeder (ADF) Print Quality Problems

The source of print quality problems from the Automatic Document Feeder
(ADF) Unit generally come from two sources:
1. Skewing when copying from the ADF. If skewing occurs when using the
ADF, try using the platen and repeat the copy. If the image is fine from the
platen, but skews from the ADF itself, perform the skew adjustment. See
"Leading Edge Skew Adjustment" on page 53. If this adjustment does not
resolve the issue then replace the ADF Unit (page 8-11).
2. Banding defects that occur as a result of uneven feeding motion. In
this condition, the original page will pause every so often at uneven
intervals. This causes a banding pattern on the output copy. In this case,
clean the feed rollers and validate the thickness of the original document.
Any media out of specification should be copied from the document glass.
If cleaning does not solve the problem, then replace the ADF Unit
(page 8-11.
The printed copies are either blank or solid black.
Verify the media used is supported by this printer.
Verify the media settings are correct at the Control Panel.
