Replacing the drum unit C
Order Number: DR-110CL
Change Parts Drum message C
Change Parts
Drum
The machine uses a drum unit to create print
images on paper. If the LCD shows
Change Parts Drum, 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 Parts
Drum
, 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 Parts
Drum
appears), then
the drum unit should be replaced. You should
clean the machine when you replace the drum
unit. (See
Cleaning the laser scanner
windows on page 154
.)
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 17,000 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.
Replacing the drum unit C
CAUTION
Wait to unpack a new drum unit until
immediately before installing it. Put the old
drum unit into the plastic bag.
HOT SURFACE
After you have just used the machine, some
internal parts of the machine will be
extremely hot. When you open the front or
back cover of the machine, DO NOT touch
the shaded parts shown in the illustration.
