CONDITION

SUGGESTED SOLUTIONS

Dropouts

If faded areas, generally rounded, occur

 

randomly on the page:

AaBbCc

• A single sheet of paper may be defective.

AaBbCc

Try reprinting the job.

• The moisture content of the paper is

AaBbCc

uneven or the paper has moist spots on its

AaBbCc

surface. Try a different brand of paper.

See "Selecting print media" on page 24.

AaBbCc

• The paper lot is bad. The manufacturing

 

processes can cause some areas to reject

 

toner. Try a different kind or brand of

 

paper.

•Change the printer option and try again. Go to printer properties, click Paper tab, and set type to Thick Paper. Refer to the Software section for details.

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

White Spots

White spots appear on the page:

•The paper is too rough and a lot of dirt from

the paper falls to the inner devices within the printer, which means the transfer belt may be dirty. Clean the inside of your printer. Contact a service representative.

• The paper path may need cleaning. Contact a service representative.

Vertical lines

If black vertical streaks appear on the page:

•The drum inside the toner cartridge has probably been scratched. Remove the

toner cartridge and install a new one. See "Replacing the toner cartridge" on page 53.

If white vertical streaks appear on the page:

•The surface of the LSU part inside the

printer may be dirty. Clean the LSU, contact a service representative.

Color or Black

If the amount of background shading becomes

background

unacceptable:

•Change to a lighter weight paper.

See "Selecting print media" on page 24.

•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 toner cartridge and install

 

a new one. See "Replacing the toner

 

cartridge" on page 53.

Toner smear

• Clean the inside of the printer.

 

See "Cleaning the inside" on page 50.

 

• Check the paper type and quality.

 

See "Selecting print media" on page 24.

 

• Remove the toner cartridge and install a

 

new one. See "Replacing the toner

 

cartridge" on page 53.

CONDITION

SUGGESTED SOLUTIONS

Vertical repetitive

If marks repeatedly appear on the printed side

defects

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. After the printout, if you still have

 

the same problems, remove the toner

 

cartridge and install a new one.

 

See "Replacing the toner cartridge" on

 

page 53.

 

• 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.

Background scatter Background scatter results from bits of toner randomly distributed on the printed page.

A

• 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.

• If background scatter occurs on an

envelope, change the printing layout to

 

avoid printing over areas that have

 

overlapping seams on the reverse side.

 

Printing on seams can cause problems.

•If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or the printer properties.

Misformed

• If characters are improperly formed and

characters

producing hollow images, the paper stock

 

may be too slick. Try a different paper.

 

See "Selecting print media" on page 24.

 

• If characters are improperly formed and

 

producing a wavy effect, the scanner unit

 

may need service. For service, contact a

 

service representative.

Page skew

• Ensure that the paper is loaded properly.

AaBbCc

• Check the paper type and quality.

See "Selecting print media" on page 24.

AaBbCc

• Ensure that the paper or other material is

loaded correctly and the guides are not too

AaBbCc

tight or too loose against the paper stack.
