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 LCD shows
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 LCD 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 13-19.)
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.
WARNING
Just after you have used the
machine, some internal parts
of the machine are extremely
HOT! So please be careful.
Follow these steps to replace
the drum unit:
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 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.
