Reinstall the drum unit
and close the front cover.

Replacing the Drum Unit

The machine uses a drum unit to create print images on paper. If the
screen displays CHANGE DRUM SOON, the drum unit is near the end of
its life and it is time to purchase a new one.
Even if the display shows CHANGE DRUM SOON, 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 CHANGE DRUM SOON is shown), then the drum unit
should be replaced. You should clean the machine when you replace the
drum unit. (See page 17-22.)
Caution
When removing the drum unit, handle it carefully because it contains
toner. If toner scatters and your hands or clothes get dirty, immediately
wipe or wash with cold water.
The drum unit is a consumable, 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, etc. The estimated drum life is
up to 20,000 pages. The actual number of pages your drum will print may
be significantly less than these estimates. 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.
WARNING
Just after you have used
HOT!
the machine, some
internal parts of the
machine are extremely

careful.
