Troubleshooting_ 79

•

The paper may not meet specifications; for 
example, the paper is too moist or too 

rough. (See "Selecting print media" on 

•

The paper path may need cleaning. (See 

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 35.)

•

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 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.

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 65.)

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.

If the amount of background shading becomes 

unacceptable:

•

Change to a lighter weight paper. (See 

•

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 65.)

•

Clean the inside of the machine. (See 
"Cleaning the inside" on page 62.)

•

Check the paper type and quality. (See 

"Selecting print media" on page 35.)

•

Remove the toner cartridge and install a 

new one. (See "Replacing the toner 

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 

•

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 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.

•

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 35.)

•

If characters are improperly formed and 

producing a wavy effect, the scanner unit 
may need service. For service, contact a 

service representative.
