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; see "
Cleaning the Drum
"
. After the
printout, if you still have the same problems, install a new toner cartridge. See "
Replacing
the Toner Cartridge
"
.
Parts of the printer 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 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 produce hollow images, the paper stock may be
too slick. Try a different paper. See "
Paper Specifications
"
.
If characters are improperly formed and produce a wavy effect, the scanner unit may need
service. For service, contact a service representative.
