b

Slowly take out the drum unit and toner 
cartridge assembly.

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.

c

Push down the green lock lever and take  
the toner cartridge out of the drum unit.

CAUTION

To avoid print quality problems, DO NOT 
touch the shaded parts shown in the 
illustrations.

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.
