Color or Black
background
If the amount of background shading becomes
unacceptable:
Change to a lighter weight paper. See
page 33.
Check the machine’s environment: very dry
(low humidity) or high humidity (higher than
80% RH) conditions can increase the
amount of background shading.
Remove the old toner cartridge and install
a new one. See page 65.
Toner smear
Clean the inside of the machine. See page
62.
Check the paper type and quality. See page
33.
Remove the toner cartridge and install a
new one. See page 65.
Vertical repetitive
defects
If marks repeatedly appear on the printed side
of the page at even intervals:
The toner cartridge may be damaged. If a
repetitive mark occurs on the page, print a
cleaning sheet several times to clean the
cartridge. After the printout, if you still have
the same problems, remove the toner
cartridge and install a new one. See page
65.
Parts of 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
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 the printer properties.
