Replacing the drum unit
(DR-350)
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 buy 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
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 11-22.)
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 up to 12,000 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.
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 it off with
cold water.
WARNING
Just after you have used the
machine, some internal parts of the
machine are extremely HOT! So please
be careful.
