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 papers. 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 page
5.7.
• If characters are improperly formed and
producing a wavy effect, the scanner unit may
need service. For service, contact a service
representative.
Page skew

• Check the paper type and quality. See
• Ensure that the paper or other material is
loaded correctly and the guides are not too
tight or too loose against the paper stack.

temperature and humidity can cause the
paper to curl. See page 5.7.

Character Voids
Character voids are white areas within parts of
characters that should be solid black:
• If you are using transparencies, try another
type of transparency. Because of the
composition of transparencies, some
character voids are normal.

the paper. Remove the paper and turn it
