Troubleshooting_ 73
Vertical repetitive
defects If marks repeatedly appear on the printed side of
the page at even intervals:
• The toner cartridge may be damaged. If a
repetitive mark occurs on the page, print a
cleaning sheet several times to clean the
cartridge. After the printout, if you still have the
same problems, remove the toner cartridge and
install a new one. See page 61.
• Parts of the machine may have toner on them.
If the defects occur on the back of the page, the
problem will likely correct itself after a few more
pages.
• The fusing assembly may be damaged.
Contact a service representative.
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.
• 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 31.
• If characters are improperly formed and
producing a wavy effect, the scanner unit may
need service. For service, contact a service
representative.
Page skew • Ensure that the paper is loaded properly.
• Check the paper type and quality. See page 31.
• Ensure that the paper or other material is loaded
correctly and the guides are not too tight or too
loose against the paper stack.
