Troubleshooting

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 "Selecting print media" on page 28.)

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 machine, which means the transfer belt

may be dirty. Clean the inside of your

machine. 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 48.)

If white vertical streaks appear on the page:

The surface of the LSU part inside the

machine may be dirty. Clean the LSU,

contact a service representative.

Color or Black
background

If the amount of background shading becomes

unacceptable:

Change to a lighter weight paper. (See

"Selecting print media" on page 28.)

Check the machine’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 48.)

Toner smear

Clean the inside of the machine. (See

"Cleaning the inside" on page 45.)

Check the paper type and quality. (See

"Selecting print media" on page 28.)

Remove the toner cartridge and install a

new one. (See "Replacing the toner

cartridge" on page 48.)

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. 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 48.)

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

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
characters

If characters are improperly formed and

producing hollow images, the paper stock

may be too slick. Try a different paper. (See

"Selecting print media" on page 28.)

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.

Check the paper type and quality. (See

"Selecting print media" on page 28.)

Ensure that the paper or other material is

loaded correctly and the guides are not too

tight or too loose against the paper stack.
