Vertical lines
If black vertical streaks appear on the page:
• A toner cartridge has probably been scratched.
Remove the toner cartridge and install a new one.
See page 6.4.
If white vertical lines appear on the page:
• Clean the inside of the printer. See “Cleaning the
Inside of the Printer” on page 6.8. If you still have
the same problems, replace the toner cartridge with
a new one. See page 6.4.
Color or Black
background
If the amount of background shading becomes
unacceptable, the procedures below may fix the
problem.
• Change to lighter weight paper. See “Paper
Specifications” on page 10.1.
• Check the printer's environment; very dry (low
humidity) or high humidity (higher than 80% RH)
conditions can increase the amount of background
shading.
• Remove one of the old toner cartridges and install a
new one.
Toner smear
• Clean the inside of the printer. See “Cleaning the
Inside of the Printer” on page 6.8
• Check the paper type and quality. See “Paper
Specifications” on page 10.1.
• Remove the paper transfer belt and install a new
one. See “Replacing the Paper Transfer Belt” on
page 6.5.
Vertical
repetitive
defects
If marks repeatedly appear on the printed side of the
page at even intervals:
• Clean the inside of the printer. See “Cleaning the
Inside of the Printer” on page 6.8. After cleaning
the inside of the printer, if you still have the same
problems, install a new toner cartridge of the
problem color. See “Replacing Toner Cartridges” on
page 6.4.
• 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.

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 “Paper Specifications” on
page 10.1.
• If characters are improperly formed and producing
a wavy effect, the scanner unit may need service.
Verify that it also occurs on a demo page. See
page 2.7. For service, contact a service
representative.
Page skew
• Ensure that the paper is loaded properly.
• Check the paper type and quality. See “Paper
Specifications” on page 10.1.
• Ensure that the paper or other material is loaded
correctly and the 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 high humidity can cause paper
curl. See “Paper Specifications” on page 10.1.
• Turn the stack of paper over in the tray. Also try
rotating the paper 180° in the tray.
Wrinkles or
creases
• Ensure that the paper is loaded properly.
• Check the paper type and quality. See “Paper
Specifications” on page 10.1.
• Turn the stack of paper over in the paper tray. Also
try rotating the paper 180° in the tray.
