3 With a dry lint-free cloth, wipe away any dust and spilled
toner from the toner cartridge area and the toner cartridge
cavity.
C AUTION : While cleaning the inside of the machine, be careful
not to touch the transfer roller, located underneath the toner
cartridge. Oil from your fingers can cause print scan quality
problems.
4 Locate the long strip of glass (LSU) inside the top of the
toner cartridge compartment, and gently swab the glass to
see if dirt turns the white cotton black.
5 Reinsert the toner cartridge and close the front cover.
6 Plug in the power cord and turn the machine on.
Cleaning the drum
If there are streaks or spots on your print, the OPC drum of the
toner cartridge may require cleaning.
1 Before starting the cleaning procedure, make sure that
paper is loaded in the machine.
2 Press Menu until Maintenance appears on the top line of
the display.
3 Press OK when Clean Drum appears.
The machine prints out a cleaning page. Toner particles on
the drum surface are affixed to the paper.
4 If the problem remains, repeat steps 1 through 3.
Cleaning the scan unit
