Follow these steps to replace the drum unit:
1
Open the front cover.
2
Remove the old drum unit. Place the drum
unit on a drop cloth or disposable paper to
avoid scattering toner.
3
Hold down the lock lever on the right and
pull the toner cartridge out of the drum unit
assembly. (See Replacing the Toner
Cartridge, page 14-16.)
Discard the used drum unit according to local regulations. If you are not sure of
them, call your local Sanitation Department. Be sure to seal the drum unit
tightly so toner powder does not spill out of the unit. When discarding used
drum units, keep them separate from domestic garbage.
4
Wait to unpack the new drum unit until immediately before installing it. Place the
old drum unit into the aluminium bag and discard it according to local regulations.
5
Reinstall the toner cartridge into the new drum unit. (See Replacing the Toner
Cartridge, page 14-16.)
6
Reinstall the new drum unit, keeping the front cover open.
7
Press Clear Settings.
8
Press 1 and when the LCD shows
ACCEPTED, and close the front cover.
Caution
If toner scatters and your hands or clothes get dirty, immediately wipe it off or
wash it with cold water.
