<Troubleshooting>
White Spots White spots appear on the page:
• The paper is too rough and a lot of dirt from
the paper falls to the inner devices within
the machine, which means the transfer belt
may be dirty. Clean the inside of your
machine. Contact a service representative.
• The paper path may need cleaning. Contact
a service representative.
Vertical lines If black vertical streaks appear on the page:
• The toner cartridge has probably been
scratched. Remove the toner cartridge and
install a new one.
If white vertical streaks appear on the page:
• Clean the inside of the machine. Contact a
service representative to clean the inside of
the machine.
Color or Black
background If the amount of background shading becomes
unacceptable:
• Change to a lighter weight paper. (See
"Specifications on print media" on page 4.2.)
• 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 then
install a new one. (See "Replacing the toner
cartridge" on page 6.4.)
Toner smear • Clean the inside of the machine. Contact a
service representative to clean the inside of
the machine.
• Check the paper type and quality. (See
"Specifications on print media" on page 4.2.)
• Remove the paper transfer belt, and then
install a new one. (See "Replacing the toner
cartridge" on page 6.4.)
Condition Suggested solutions
Vertical repetitive
defects If marks repeatedly appear on the printed side
of the page at even intervals:
• Clean the inside of the machine. Contact a
service representative to clean the inside of
the machine. After cleaning the inside of the
machine, if you still have the same
problems, install a new toner cartridge of the
problem color. See "Replacing the toner
cartridge" on page 6.4.
• 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 in printer properties.
Misformed
characters • If characters are improperly formed and
producing hollow images, the paper stock
may be too slick. Try different paper. (See
"Specifications on print media" on page 4.2.)
Page skew • Ensure that the paper is loaded properly.
• Check the paper type and quality. (See
"Specifications on print media" on page 4.2.)
• Ensure that the paper or other material is
loaded correctly and the guides are not too
tight or too loose against the paper stack.
