Misformed
Characters If the text characters are improperly formed
and produce:
•
A hollow image, the paper stock may be
too slick. Try a different paper.
• A wavy effect, the scanner unit may
need service. Verify that it occurs by
printing a demo page.
Page Skew If the page prints at an unplanned angle:
•
Check the paper type and quality.
• Make sure that the paper or other media
is loaded correctly and the guides are
not too tight or too loose against the
paper stack.
Character Voids Character voids are white area within the
parts of characters that should be solid black:
•
If you are using transparencies when
you experience this problem, try another
type of transparency.
• Because of the composition of
transparency media, some character
voids are normal.
• The paper may not meet paper
specifications.
Problem Solution
Gray Background If the amount of background toner shading
becomes unacceptable, the procedures
below may help to clear the condition:
•
Change the paper to a lighter basis
weight. See Appendix XX, “Paper
Specifications.”
• Check the printer’s environment, very
low or high humidity conditions can
increase the amount of background
shading.
• Install a new Toner Cartridge.
Background
Scatter Background scatter results from bits of toner
distributed on the printed page:
•
The paper may be too damp. Try printing
on a different batch of paper. Do not
open packages of paper until necessary
so that the paper does not absorb too
much moisture from the air.
• If background scatter occurs on an
envelope, change your printing layout to
avoid printing over areas that have
overlapping seams on the reverse side.
Printing on seams can cause this
problem.
• If background scatter covers the entire
surface of a printed page, adjust the
print resolution through your software
application or the printer properties.
