Replacing the drum unit C
The machine uses a drum unit to create print
images on paper. If the LCD shows
Replace 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 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 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 144.)
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.
Note
The drum unit is a consumable item, and
it is necessary to replace it periodically.
There are many factors that determine the
actual drum life, such as temperature,
humidity, type of paper and how much
toner you use for the number of pages per
print job. The estimated drum life is
approximately 25,000 pages
1
. The actual
number of pages your drum will print may
be significantly less than this estimate.
Because we have no control over the
many factors that determine the actual
drum life, we cannot guarantee a
minimum number of pages that will be
printed by your drum.

Drum yield is approximate, and may vary by type of
use.
CAUTION
HOT SURFACE
After you have just used the machine, some
internal parts of the machine will be
extremely hot. To prevent injury, when you
open the front or back cover (back output
tray) of the machine DO NOT touch the
shaded parts shown in the illustration. If you
do this you may get burned.
a Press the front cover release button and
open the front cover.
b Slowly take out the drum unit and toner
cartridge assembly.
