Vertical linesIf black vertical streaks appear on the page:
• The imaging unit inside the printer has probably been 
scratched. Install a new imaging unit. 
If white vertical lines appear on the page:
• The Laser Scanner window has probably been contaminated. 
Clean the Laser Scanner window. Holding the end of the 
cleaner, slide it in and out several times. See “Cleaning the 
LSU Inside the Printer” on page 6.30.
Color or Black 
backgroundIf the amount of background shading becomes unacceptable, 
the procedures below may fix the problem.
• Change to lighter weight pages. See “Paper Specifications” on 
page G.4.
• 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 the old imaging unit and install a new one. See 
“Replacing the Imaging Unit” on page 6.14.
Toner smear• Clean the inside of the printer. See “Cleaning the Inside of the 
Printer” on page 6.31
• Check the paper type and quality. See “Paper Specifications” 
on page G.4.
• Remove the transfer belt and install a new one. See “Replacing 
the Transfer Belt” on page 6.22.
Vertical repetitive 
defectsIf 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 6.31. After cleaning the inside of the printer, 
if you still have the same problems, install a new toner 
cartridge of the defected color. See “Replacing the Toner 
Cartridges” on page 6.8.
• 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 scatterBackground 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 the printer properties.
Misformed 
characters• If characters are improperly formed and produce hollow 
images, the paper stock may be too slick. Try a different paper. 
See “Paper Specifications” on page G.4.
• If characters are improperly formed and produce a wavy 
effect, the scanner unit may need service. Verify that it also 
occurs on a demo page. Refer to the Setup Guide. For service, 
contact a service representative.
Page skew• Check the paper type and quality. See “Paper Specifications” 
on page G.4.
• 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• Check the paper type and quality. Both high temperatures and 
humidity can cause paper to curl. See “Paper Specifications” on 
page G.4.
• Turn the stack of paper over in the tray. Also try rotating the 
paper 180° in the tray.
Wrinkles or 
creasesEnsure that the paper is loaded properly.
• Check the paper type and quality. See “Paper Specifications” 
on page G.4.
• Turn the stack of paper over in the paper tray. Also try rotating 
the paper 180° in the tray.

Contact a service representative.
Character VoidsCharacter voids are white areas within parts of characters that 
should be solid black:
• If you are using transparencies, try another type of 
transparency. Due to the composition of the transparency, 
some character voids are normal. 
• You may be printing on the wrong surface on the paper. 
Remove the paper and turn it around. 
• The paper may not meet paper specifications. See page G.4.
Horizontal stripesIf horizontally aligned color or black streaks or smears appear:
• The imaging unit may be installed improperly. Remove the 
imaging unit and reinsert.
