Cleaning the corona wires
C
If you have print quality problems, clean the
corona wires as follows:
a
Turn off the machine’s power switch.
Disconnect all cables, and then unplug
the power cord from the AC power outlet.
b
Fully open the top cover by lifting up on
the handle (1).
IMPORTANT
When the scanner is open, you cannot
open the top cover.
c
Take out the drum unit and toner
cartridge assemblies.
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.
• To prevent damage to the machine from
static electricity, DO NOT touch the
electrodes shown in the illustration.
d
Clean the primary 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.
