Replacing the drum unit
(DR-3100) C
The machine uses a drum unit to create print
images on paper. If the LCD shows Drum
Near End, the drum unit is near the end of its
life and it is time to buy a new one.
Even if the LCD shows Drum Near End, 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 Drum
Near End 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 118.)
CAUTION
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 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.
