Solving Print Quality Problems

 

Problem

Solution

 

Toner specs

• The paper may not meet specifications (for example, the

 

 

 

paper is too moist or too rough). See “Paper Specifications”

 

 

 

on page A.2.

 

 

 

• The transfer roller may be dirty. See “Cleaning the Inside”

 

 

 

on page 6.4.

 

 

 

• The paper path may need cleaning. See “Cleaning the

 

 

 

Inside”.

 

 

 

 

 

Dropouts

If faded areas, generally rounded, occur randomly on the

 

 

 

page:

 

 

 

• A single sheet of paper may be defective. Try reprinting the

 

 

 

job.

 

 

 

• The moisture content of the paper is uneven or the paper

 

 

 

has moist spots on its surface. Try a different brand of

 

 

 

paper. See “Paper Specifications” on page A.2.

 

 

 

• The paper lot is bad. The manufacturing processes can

 

 

 

cause some areas to reject toner. Try a different kind or

 

 

 

brand of paper.

 

 

 

• The toner cartridge may be defective. See “Vertical

 

 

 

repetitive defects” on the next page.

 

 

 

• If these steps do not correct the problems, contact a

 

 

 

service representative.

 

 

 

 

 

Vertical lines

 

 

 

 

If black vertical streaks appear on the page:

 

 

 

• The drum inside the toner cartridge has probably been

 

 

 

scratched. Install a new toner cartridge.

Gray background

If the amount of background shading becomes unacceptable,

 

the procedures below may fix the problem.

 

• Change to a lighter weight pages. See “Paper

 

Specifications” on page A.2.

 

• Check the printer’s environment; very dry (low humidity)

 

or high humidity (higher than 80% RH) conditions can

 

increase the amount of background shading.

 

• Install a new toner cartridge.

Toner smear

• Clean the inside of the printer. See “Cleaning the Inside”

 

on page 6.4.

 

• Check the paper type and quality. See “Paper

 

Specifications” on page A.2.

 

• Install a new toner cartridge.

Vertical repetitive defects

If marks repeatedly appear on the printed side of the page

 

at even intervals:

 

• The toner cartridge may be damaged. If a repetitive mark

 

occurs on the page, print a cleaning sheet several times to

 

clean the cartridge (see page 6.5). After the printout, if

 

you still have the same problems, install a new toner

 

cartridge.

 

• Parts of the printer 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.
