Troubleshooting

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 81).

•

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 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 53).

•

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 53). 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 78).

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 53).

•

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.
