Replacing the drum unit
A
Order No. DR-720
A new drum unit can print approximately
30,000 Letter or A4 size single-sided pages.
Note
There are many factors that determine the
actual drum life, such as the temperature,
humidity, type of paper, type of toner used
and so on. Under ideal conditions, the
average drum life is estimated at
approximately 30,000 pages. The actual
number of pages that your drum will print
may be significantly less than this
estimate. 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.
For best performance, use only genuine
Brother toner. The machine should be
used only in a clean, dust-free
environment with adequate ventilation.
Printing with a non-Brother drum unit may
reduce not only the print quality but also
