Background
scatter
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.

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 in Printing Preferences. (See
Misformed
characters

If characters are improperly formed and
producing hollow images, the paper stock
may be too slick. Try different paper. (See
