Page skew
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.
