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
CAUTION
Wait to unpack a new drum unit until
