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.
