Printing quality problems
Condition
Background scatter
A
Toner particles are around bold
characters or pictures
Misformed characters
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.
Or select Thick from the Printing Preferences window (see "Opening Printing Preferences" on page 52).
• 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 52). 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 70).
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 52).
• 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 characters are improperly formed and producing hollow images, the paper stock may be too slick. Try different paper.
