b Slowly take out the drum unit and toner

CAUTION
We recommend that you put the drum unit
and toner cartridge assembly on a clean,
flat surface with a sheet of disposable
paper or cloth underneath it in case you
accidentally spill or scatter toner.
To prevent damage to the machine caused
by static electricity, DO NOT touch the
electrodes shown in the illustration.

the toner cartridge out of the drum unit.
CAUTION
To avoid print quality problems, DO NOT

Wait to unpack a new drum unit until
immediately before you put it in the
machine. Exposure to direct sunlight or
room light may damage the drum unit.
Note
Be sure to seal up the used drum unit
tightly in a bag so that toner powder does
not spill out of the unit.
d Unpack the new drum unit.
e Put the toner cartridge firmly into the
new drum unit until you hear it lock into
place. If you put the cartridge in
properly, the green lock lever will lift
automatically.
CAUTION
Make sure that you put in the toner
cartridge properly or it may separate from
the drum unit.
