Condition
Vertical repetitive If marks repeatedly appear on the printed side
defects of the page at even intervals:
• The drum cartridge may be damaged. If a
repetitive mark occurs on the page, run a
cleaning sheet through several times to
clean the cartridge; contact a service
representative. After the printout, if you still
have the same problems, remove the drum
cartridge and then, install a new one.
(Page 10.3)
• 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 in printer properties.
Misformed • If characters are improperly formed and
characters producing hollow images, the paper stock
may be too slick. Try different paper.
(Page 4.3)
• If characters are improperly formed and
producing a wavy effect, the scanner unit
may need service. Contact a service
representative.
