CONDITION

SUGGESTED SOLUTIONS

 

 

 

Black background

If the amount of background shading becomes unacceptable:

 

 

Change to a lighter weight paper (See "Print media specifications" on page71).

 

 

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 page68).

 

 

 

 

 

 

Toner smear

If toner smears on the page:

 

 

Clean the inside of the machine (See "Cleaning the inside" on page48).

 

 

Check the paper type and quality (See "Print media specifications" on page71).

 

 

Remove the toner cartridge and then, install a new one (See "Replacing the toner

 

 

 

cartridge" on page68).

 

 

 

 

 

 

 

 

Vertical repetitive

 

If marks repeatedly appear on the printed side of the page at even intervals:

defects

 

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 page68).

 

 

 

 

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

 

 

A

 

 

packages of paper until necessary so that the paper does not absorb too much moisture.

 

 

 

 

 

 

 

 

 

 

 

Misformed

If characters are improperly formed and producing hollow images, the paper stock may be

characters

too slick. Try different paper (See "Print media specifications" on page71).
