Troubleshooting and routine maintenance

f
Put the new toner cartridge firmly into
the drum unit until you hear it lock into
place. If you put it in correctly, the lock
lever will lift automatically.
Note
Make sure that you put in the toner
cartridge correctly or it may separate from
the drum unit.
g
Clean the corona wire of the drum unit
by gently sliding the blue tab from right
to left and left to right several times.
Note
Be sure to return the blue tab to the home
position (a) (1). If you do not, printed
pages may have a vertical stripe.
h
Put the drum unit and toner cartridge
assembly back in the machine.
i
Close the front cover.
Note
DO NOT turn off the machine or open the
front cover until the LCD returns to the
standby state.
Replacing the drum unit
C
The machine uses a drum unit to create print
images on paper. If the LCD shows
Replace Parts Drum, the drum unit is
near the end of its life and it is time to buy a
new one. Even if the LCD shows
Replace Parts Drum, you may be able to
continue printing without having to replace
the drum unit for a while. However, if there is
a noticeable deterioration in the output print
quality (even before Replace Parts Drum
appears), then the drum unit should be
replaced. You should clean the machine
when you replace the drum unit. (See
Cleaning the laser scanner window
on page 138.)
IMPORTANT
While removing the drum unit, handle it
carefully because it may contain toner. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
