been scratched. Remove the drum cartridge
and install a new one. See page 13.5.

• 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

Vertical repetitive If marks repeatedly appear on the printed side
defects 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.
