Background 
scatter
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 the printer properties.
Misformed 
characters
• If characters are improperly formed and producing hollow 
images, the paper stock may be too slick. Try a different 
paper. See “Paper Specifications” on page A.6.
• If characters are improperly formed and producing a wavy 
effect, the scanner unit may need service. For service, 
contact a service representative.
Page skew
• Ensure that the paper is loaded properly.
• Check the paper type and quality. See “Paper Specifications” 
on page A.6.
• Ensure that the paper or other material is loaded correctly 
and the guides are not too tight or too loose against the 
paper stack.
Curl or wave
• Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high temperature and 
humidity can cause paper curl. See “Paper Specifications” on 
page A.6.
•Turn over the stack of paper in the paper tray. Also try 
rotating the paper 180° in the tray.
