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
via the printer properties window.
Misformed
characters
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.
