Solving print quality problems

Dirt inside of the printer or improper paper loading may reduce print quality. See the table below to troubleshoot problems.

Condition

Suggested solutions

 

 

Light or faded

If a vertical white streak or faded area appears

print

on the page:

• The toner supply is low. You may be able to temporarily extend the toner cartridge life. See page 8.3. If this does not improve print quality, install a new toner cartridge.

• The paper may not meet paper specifications (for example, the paper is too moist or too rough). See page 5.3.

If the entire page is light, the print resolution setting is too light or toner save mode is on. Adjust the print resolution and toner save mode in the printer properties. See the Software Section.

A combination of faded or smeared defects may indicate that the printer needs cleaning. See page 8.1.

The surface of LSU may be dirty. Clean the LSU. See page 8.2.

Toner spots

The paper may not meet specifications (for

 

 

example, the paper is too moist or too rough).

 

 

See page 5.3.

 

The transfer roller or paper path may be dirty.

 

 

See page 8.1.

Dropouts

If generally rounded, faded areas 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 page 5.3.

• 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 column.

If these steps do not correct the problems, contact a service representative.

Suggested solutions

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. See page 8.4.

 

If white vertical streaks appear on the page:

 

The surface of the LSU part inside the printer

 

 

may be dirty. Clean the LSU. See page 8.2.

Gray

If the amount of background shading becomes

background

unacceptable, the procedures below may fix the

 

problem.

 

Change to lighter weight pages. See page 5.3.

 

Check the printer’s environment; low humidity

 

 

(lower than 20% RH) or high humidity (higher

 

 

than 80% RH) conditions can increase the

 

 

amount of background shading.

 

Remove the old toner cartridge and install a

 

 

new one. See page 8.4.

Toner smear

Clean the inside of the printer. See page 8.1.

 

Check the paper type and quality. See page

 

 

5.2.

 

Remove the toner cartridge and install a new

 

 

one. See page 8.4.

Vertical

If marks repeatedly appear on the printed side of

repetitive

the page at even intervals:

defects

The toner cartridge may be damaged. If a

 

 

 

 

 

repetitive mark occurs on the page, install a

 

 

 

 

 

 

 

 

 

 

new toner cartridge. See page 8.4.

 

 

 

 

• 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.
