Color fades with fuzzy, poorly
defined edges. Ensure the absorption roll/charge roll on
the belt is securely seated. The black
plastic T-shaped bushing should both be
below the flap on the right side of the belt.
A poorly seated roll can cause both
skewing of the paper and problems with
the magenta print.
Check that the top cover is firmly closed
on the printer. If the cover is not closed
completely, the LED may be out of focus
and allow light print on the bottom of a
letter size page. Close the cover firmly
and test.
Print the quality pages in the Diagnostics
Mode (under Print Test, Print Quality
Pages). This often identifies the color that
has a problem. If you switch the toner
cartridges and the problem also changes
color on the test pages, the problem is in
one of the cartridges. Replace the proper
color cartridge.
Toner adheres to the back of the
page. Remove the fuser oil roll and wipe it with
a dry, lint-free cloth, and clean the
transfer belt. If there still is a problem, go
to
“Periodic dirt” on page 2-97 .
Quality of printed transparencies
is inadequate. Be sure you’re using the recommended
Lexmark transparencies.
Be sure you have selected the correct
paper weight setting for the media you
are using.
When printing transparencies, always set
the Paper Type to Transparency.
Avoid getting fingerprints on
transparencies before printing.
