Problem
Possible Cause and Remedy
If marks repeatedly appear on the printed side of the page at
even intervals:
• The toner cartridge may be damaged. Print a cleaning
sheet several times by cleaning the OPC drum (see
page 6.2). After the printout, if you still have the same
problems, install a new toner cartridge.
• Parts in the machine may have toner on them. If the
defects occur on the back of the page, the problem will
likely correct itself after a few more pages.
• The fusing assembly may be damaged. Contact a service
representative.

Background scatter results from bits of toner distributed on
the printed page.
• The paper may be too damp. Try printing with a different
batch of paper. Do not open packages of paper until
necessary so that the paper does not absorb too much
moisture from the air.
• If background scatter occurs on an envelope, change your
printing layout to avoid printing over areas that have
overlapping seams on the reverse side. Printing on seams
can cause this problem.
• If background scatter covers the entire surface of a printed
page, adjust the print resolution through your software
application or the printer properties.

• If characters are improperly formed, producing hollow
images, the paper stock may be too slick. Try a different
paper. See “Paper Type and Size” for faxing on page 1.17
and “Selecting Print Media” for PC printing on page 4.1.
• If characters are improperly formed, producing a wavy
effect, the scanner unit may need service. Verify that it also
occurs on a demo page.
Press Demo ( ) on the front panel when the machine is
ready.
If you need service, contact a service representative.
