Replacing the drum unit
(DR-350)
The DCP 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 DCP when you replace the drum
unit. (See Cleaning the laser scanner window
on page 6-17.)
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.
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.
