<Troubleshooting>

If black vertical streaks appear on the page:
• The drum inside the printer has probably 

been scratched. Remove the drum cartridge 
and install a new one. See page 13.5.

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 

page 5.3.

• 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 drum and toner cartridge 

and then, install a new one. See page 13.4.

• Clean the inside of the machine. Contact a 

service representative.

• Check the paper type and quality. See 

page 5.3.

• Remove the drum and toner cartridge and 

then, install a new one. See page 13.4.

If marks repeatedly appear on the printed side 
of the page at even intervals:
• The drum and toner cartridge may be 

damaged. If a repetitive mark occurs on the 
page, print a cleaning sheet several times to 
clean the cartridge; contact a service 
representative. After the printout, if you still 
have the same problems, remove the drum 
and toner cartridge and then, install a new 
one. See page 13.4.

• 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 the printer properties.

• If characters are improperly formed and 

producing hollow images, the paper stock 
may be too slick. Try a different paper. See 
page 5.3.

• If characters are improperly formed and 

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

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

page 5.3.

• 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 page 5.3.

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

try rotating the paper 180° in the tray.
