Replacing the drum unit

Order No. DR-351CL
A new drum unit can print approximately
25,000 A4 or Letter size single-sided pages.

Drum life is approximate and may vary by type of
use.
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 25,000 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
the quality and life of the machine itself.
Warranty coverage does not apply to
problems caused by the use of a non-
Brother drum unit.

The corona wires are coated with paper dust

drums (see Cleaning the corona wires
on page 81).
If you cleaned the corona wires and the Drum
! error was not cleared, then the drum unit is
at the end of its life. Replace the drum unit
with a new set.
