Remove the drum cartridge and install a new one. See page 13.6. If white vertical streaks appear on the page: • The surface of the LSU part inside the machine may be dirty. Clean the LSU. Contact a service representative. If the amount of background shading becomes unacceptable: • Change to a lighter weight paper. See page 5.3. • Check the machine's environment: very dry (low humidity) or high humidity (higher than 80% RH) conditions can increase the amount of background shading. • Remove the old drum and toner cartridge and then, install a new one. See page 13.4. • Clean the inside of the machine. Contact a service representative. • Check the paper type and quality. See page 5.3. • Remove the drum and toner cartridge and then, install a new one. See page 13.4. Vertical repetitive defects If marks repeatedly appear on the printed side of the page at even intervals: • The drum and toner cartridge may be damaged. If a repetitive mark occurs on the page, print a cleaning sheet several times to clean the cartridge; contact a service representative. After the printout, if you still have the same problems, remove the drum and toner cartridge and then, install a new one. See page 13.4. • 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.

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.

Troubleshooting>
Vertical lines
If black vertical streaks appear on the page:
•
The drum inside the printer has probably
been scratched. Remove the drum cartridge
and install a new one. See page 13.6.
If white vertical streaks appear on the page:
•
The surface of the LSU part inside the
machine may be dirty. Clean the LSU.
Contact a service representative.
Gray background
If the amount of background shading becomes
unacceptable:
•
Change to a lighter weight paper. See
page 5.3.
•
Check the machine’s environment: very dry
(low humidity) or high humidity (higher than
80% RH) conditions can increase the
amount of background shading.
•
Remove the old drum and toner cartridge
and then, install a new one. See page 13.4.
Toner smear
•
Clean the inside of the machine. Contact a
service representative.
•
Check the paper type and quality. See
page 5.3.
•
Remove the drum and toner cartridge and
then, install a new one. See page 13.4.
Vertical repetitive
defects
If marks repeatedly appear on the printed side
of the page at even intervals:
•
The drum and toner cartridge may be
damaged. If a repetitive mark occurs on the
page, print a cleaning sheet several times to
clean the cartridge; contact a service
representative. After the printout, if you still
have the same problems, remove the drum
and toner cartridge and then, install a new
one. See page 13.4.
•
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.
Condition
Suggested solutions
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 5.3.
•
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 5.3.
•
Ensure that the paper or other material is
loaded correctly and the guides are not too
tight or too loose against the paper stack.
Curl or wave
•
Ensure that the paper is loaded properly.
•
Check the paper type and quality. Both high
temperature and humidity can cause paper
curl. See page 5.3.
•
Turn over the stack of paper in the tray. Also
try rotating the paper 180° in the tray.
