Troubleshooting

Black background

If the amount of background shading becomes unacceptable:

•

Change to a lighter weight paper (See "Print media specifications" on page 71).

•

Check the environmental conditions: very dry conditions or a high level of humidity (higher 
than 80% RH) can increase the amount of background shading.

•

Remove the old toner cartridge and, install a new one (See "Replacing the toner cartridge" 
on page 68).

Toner smear

If toner smears on the page: 

•

Clean the inside of the machine (See "Cleaning the inside" on page 48).

•

Check the paper type and quality (See "Print media specifications" on page 71).

•

Remove the toner cartridge and then, install a new one (See "Replacing the toner 
cartridge" on page 68).

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 68).

•

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.

Misformed 
characters

•

If characters are improperly formed and producing hollow images, the paper stock may be 
too slick. Try different paper (See "Print media specifications" on page 71).
