• The paper may not meet specifications; for

AaBbCc

example, the paper is too moist or too

rough. See page 31.

• The paper path may need cleaning. See

AaBbCc

"Cleaning the inside" on page 38.

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

page 31.

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 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 imaging unit has probably been

 

 

 

 

 

 

scratched. Remove the imaging unit and

 

 

 

 

 

 

install a new one. See page 42.

 

 

 

 

 

 

If white vertical streaks appear on the page:

 

 

 

 

 

 

• The surface of the LSU part inside the

 

 

 

 

 

 

machine may be dirty. Clean the LSU by

 

 

 

 

 

 

opening and closing the front cover several

 

 

 

 

 

 

times and if the problem still occurs call the

 

 

 

 

 

 

contact a service representative.

SUGGESTED SOLUTIONS

 

 

 

 

Color or Black

If the amount of background shading becomes

background

unacceptable:

 

 

 

• Change to a lighter weight paper. See

 

 

 

page 31.

 

 

 

• 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 page 41.

 

 

 

 

 

 

 

 

Toner smear

• Clean the inside of the machine. See page

 

 

 

38.

 

 

 

• Check the paper type and quality. See page

 

 

 

31.

 

 

 

• Remove the toner cartridge and install a

 

 

 

new one. See page 41.

 

 

 

 

 

 

 

 

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 page

 

 

 

 

 

41.

 

 

 

 

 

 

 

 

 

 

• 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.

 

 

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.
