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.

• If characters are improperly formed and 

producing a wavy effect, the scanner unit may 
need service. Verify that it also occurs on a 
demo page (see page 2.6). For 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 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.

• Try printing to the rear cover (face-up).

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

• Open the rear cover and try printing to the rear 

cover (face-up).

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

rotating the paper 180° in the tray.

type of transparency. Because of the

character voids may be normal.

the paper. Remove the paper and turn it 
around.
