<Troubleshooting>

If the amount of background shading becomes 
unacceptable:
• Change to a lighter weight paper. (See 

• Check the environmental conditions: very 

dry conditions (low humidity) or a high level 
of humidity (higher than 80% RH) can 
increase the amount of background 
shading.

• Remove the old toner cartridge, and then 

install a new one. (See "Replacing the toner 
cartridge" on page 6.4.)

• Clean the inside of the machine. Contact a 

service representative to clean the inside of 
the machine.

• Check the paper type and quality. (See 

• Remove the paper transfer belt, and then 

install a new one. (See "Replacing the toner 
cartridge" on page 6.4.)

If marks repeatedly appear on the printed side 
of the page at even intervals:
• Clean the inside of the machine. Contact a 

service representative to clean the inside of 
the machine. After cleaning the inside of the 
machine, if you still have the same 
problems, install a new toner cartridge of the 
problem color. See "Replacing the toner 
cartridge" on page 6.4.

• 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 in printer properties.

• If characters are improperly formed and 

producing hollow images, the paper stock 
may be too slick. Try different paper. (See 
"Specifications on print media" on page 4.2.)

• If characters are improperly formed and 

producing a wavy effect, the scanner unit 
may need service. Contact a service 
representative.

• Ensure that the paper is loaded properly.
• Check the paper type and quality. (See 

• Ensure that the paper or other material is 

loaded correctly and the guides are not too 
tight or too loose against the paper stack.

• Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high 

temperature and humidity can cause paper 
curl. (See "Specifications on print media" on 
page 4.2.)

• Turn the stack of paper over in the tray. Also 

try rotating the paper 180° in the tray.
