Cleaning the corona wire
C
If you have print quality problems, clean the
corona wire as follows:
a
Turn off the machine’s power switch.
Unplug the telephone line cord first,
disconnect all cables, and then unplug
the power cord from the AC power
outlet.
b
Open the front cover and slowly take out
the drum unit and toner cartridge
assembly.
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.
• Handle the toner cartridge carefully. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.

caused by static electricity, DO NOT touch
the electrodes shown in the illustration.

unit by gently sliding the blue tab from

assembly back in the machine.
