<Troubleshooting>

Background scatter results from bits of toner 
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 
via the printer properties window.

• If characters are improperly formed and 

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

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

• Ensure that the paper is loaded correctly and 

the adjustable 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 5.2.

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

try rotating the paper 180° in the tray.

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

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

the printer. 

• The toner cartridge may not be installed 

properly. Remove the cartridge and reinsert.

• The toner cartridge may be defective and 

need replacing. Install a new toner cartridge.

• The printer may require repair. Contact a 

service representative.

• Clean the inside of the printer. 
• Check the paper type and quality. See page

• If the problem persists, the printer may require 

repair. Contact a service representative.

Character voids are white areas within 
characters that should be solid black:
• If you are using transparencies, try another 

type of transparency. Because of the 
composition of the transparency, some 
character voids may be normal. 

• You may be printing on the wrong surface on 

the paper. Turn over the paper in the tray. 

• The paper may not meet paper specifications.
