Vertical
repetitive
defects
If marks repeatedly appear on the printed side of the page at even
intervals:
• The toner cartridge may be damaged. If you still have the same problem,
remove the toner cartridge and, install a new one (see "Replacing the
toner cartridge" on page 129).
• 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 covers the entire surface area of a printed page,
adjust the print resolution through your software application or in
Printing Preferences (see "Opening printing preferences" on page 67).
Ensure the correct paper type is selected. For example: If Thicker Paper
is selected, but Plain Paper actually used, an overcharging can occur
causing this copy quality problem.
• If you are using a new toner cartridge, redistribute the toner first (see
"Redistributing toner" on page 128).
Toner particles
are around bold
characters or
pictures
The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to Printing Preferences,
click the Paper tab, and set the paper type to Recycled (see "Opening
printing preferences" on page 67).
• Ensure the correct paper type is selected. For example: If Thicker Paper
is selected, but Plain Paper actually used, an overcharging can occur
causing this copy quality problem.
Misformed
characters
• If characters are improperly formed and producing hollow images, the
paper stock may be too slick. Try different paper.
