Color or Black
background If the amount of background shading becomes unacceptable:

Contact a service representative.
• Check the environmental conditions: very dry conditions
(low humidity) or a high level of humidity (higher than 80%
RH) can increase the amount of background shading.
• Remove the old toner cartridge and install a new one.

occurs on the page, run a cleaning sheet through several
times to clean the imaging unit. Cleaning the inside. If you
still have the same problems, remove the imaging unit and
install a new one. Contact a service representative.

Background
scatter Background scatter results from bits of toner randomly
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.
• If background scatter occurs on an envelope, change the
printing layout to avoid printing over areas that have
overlapping seams on the reverse side. Printing on seams
can cause problems.
• If background scatter covers the entire surface area of a
printed page, adjust the print resolution through your
software application or in
Printing Preferences (see
"Opening printing preferences" on page 96).
