IMPORTANT
We recommend that you place 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.
d Push down the blue lock lever and take
the toner cartridge out of the drum unit.
Take out the jammed paper if there is
any inside the drum unit.

• 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.

inside the drum unit.

drum unit until you hear it lock into place.

lever will lift automatically.

assembly back in the machine.

the AC power outlet first, and reconnect
