Problem
Possible Cause and Remedy
If faded areas, generally rounded, occur randomly on the
page:
• A single sheet of paper may be defective. Try reprinting
the job.
• The moisture content of the paper is uneven or the paper
has moist spots on its surface. Try a different kind or
brand of paper. See “Paper Type and Size” for faxing on
page 1.17
and “Selecting Print Media” for PC printing on
page 4.1
.
• The paper lot is bad. The manufacturing processes can
cause some areas to reject toner. Try a different kind or
brand of paper.
• The toner cartridge may be defective. See “Vertical
repetitive defects” on
page 6.13
.
• If these steps do not correct the problems, contact a
service representative.

If the amount of background toner shading becomes
unacceptable, the procedures below may help to clear the
condition:
• Change the paper to a lighter weight. See “Paper Type and
Size” for faxing on
page 1.17
and “Selecting Print Media”
for PC printing on
page 4.1

• Check the printer’s environment; very dry (low humidity)
or high humidity (higher than 80 % RH) conditions can
increase the amount of background shading.
• Install a new toner cartridge.
• Adjust the shading setting. See “Adjusting Shading” on
page 5.2
