9.8
Vertical lines If black vertical streaks appear on the page:
• The drum inside the toner cartridge has
probably been scratched. Install a new toner
cartridge. See page 8.4.
If white vertical streaks appear on the page:
• The surface of the LSU part inside the printer
may be dirty. Clean the LSU. See page 8.2.
Gray
background If the amount of background shading becomes
unacceptable, the procedures below may fix the
problem.
• Change to lighter weight pages. See page 5.3.
• Check the printer’s environment; low humidity
(lower than 20% RH) 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 8.4.
Toner smear • Clean the inside of the printer. See page 8.1.
• Check the paper type and quality. See page
5.2.
• Remove the toner cartridge and install a new
one. See page 8.4.
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, install a
new toner cartridge. See page 8.4.
• Parts of the printer 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.
Condition Suggested solutions
Background
scatter 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.
• 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
via the printer properties window.
Misformed
characters • If characters are improperly formed and
producing hollowed images, the paper stock
may be too slick. Try a different paper. See
page 5.3.
Page skew • Ensure that the paper is loaded properly.
• Check the paper type and quality. See page
5.2.
• Ensure that the paper is loaded correctly and
the adjustable guides are not too tight or too
loose against the paper stack.
Curl or wave • Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high
temperature and humidity can cause paper
curl. See page 5.2.
• Turn over the stack of paper in the tray. Also
try rotating the paper 180° in the tray.
