Cleaning the drum unit

B

If you have print quality problems, clean the 
drum unit as follows.

a

Turn off the machine’s power switch. 
Unplug the power cord from the AC 
power outlet. 

b

Open the front cover.

c

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 piece 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.

d

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

CAUTION

Handle the toner cartridge carefully. If toner 
scatters on your hands or clothes, wipe or 
wash it off with cold water at once.

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