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 88.)
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

. 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.
