Cleaning the drum unit
C
If you have print quality problems, clean the
drum unit as follows.
a
Turn off the machine. Unplug the
telephone line cord first, and then
unplug the power cord from the
electrical socket.
b
Open the front cover and slowly take out
the drum unit and toner cartridge
assembly.
IMPORTANT
• 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 blue lock lever and take
the toner cartridge out of the drum unit.
IMPORTANT
• 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.
d
Put the print sample in front of the drum
unit, and find the exact position of the
poor print.
