b 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,
immediately wipe or wash it off with cold
water.
To prevent damage to the machine
caused by static electricity, DO NOT touch
the electrodes shown in the illustration.
c Clean the corona wire inside the drum
unit by gently sliding the green tab from
left to right and right to left several times.
Note
Be sure to return the tab to the home
position (a) (1). If you do not, printed
pages may have a vertical stripe.
