Troubleshooting>

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 on

the page:

• The toner supply is low. You may be able to

temporarily extend the print cartridge life. See

page 8.3. If this does not improve print quality,

install a new print 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 8.1.

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 print 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 print cartridge has

probably been scratched. Install a new print

cartridge.

Gray

background

If the amount of background shading becomes

unacceptable, the procedures below may fix the

problem.

• Change to lighter weight pages. See page 5.3.

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

humidity) or high humidity (higher than 80%

RH) conditions can increase the amount of

background shading.

• Remove the old print cartridge and install a new

one. See page 8.3.

Toner smear

• Clean the inside of the printer. See page 8.1.

• Check the type and quality. See page 5.2.

• Remove the print cartridge and install a new

one. See page 8.3.

Vertical

repetitive

defects

If marks repeatedly appear on the printed side of

the page at even intervals:

• The print cartridge may be damaged. If a

repetitive mark occurs on the page, print a

cleaning sheet several times to clean the

cartridge; see page 8.1. After the printout, if

you still have the same problems, install a new

print cartridge. See page 8.3.

• 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.
