Troubleshooting

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 3.2.

• 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 3.2.
• 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 3.2.

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

rotating the paper 180° in the tray.

• Try printing to the rear cover.

Check for leaking toner. Clean the inside of the 

machine. See page 8.1.

• The toner cartridge may not be installed properly. 

Remove the toner cartridge and reinsert it.

• The toner cartridge may be defective and need 

replacing. Remove the toner cartridge and install 
a new one. See page 8.4.

• The machine may require repair. Contact a service 

representative.

See page 8.4.

• If the problem persists, the machine may require 

repair. Contact a service representative.

Character voids are white areas within parts of 

characters that should be solid black:
• If you are using transparencies, try another type 

of transparency. Because of the composition of 
transparencies, some character voids are normal. 

• You may be printing on the wrong surface of the 

paper. Remove the paper and turn it around. 

• The paper may not meet paper specifications. See
