Drum life is approximate and may vary by type of
use.
For best performance, use a Brother
Original drum unit and Brother Original
toner units. Printing with a third-party drum
unit or toner unit may reduce not only the
print quality but also the quality and life of
the machine itself. Warranty coverage
may not apply to problems caused by the
use of a third-party drum unit or toner unit.
Drum ! A
The corona wires are coated with paper dust
or toner. Clean the corona wires in the four
drums (see Cleaning the corona wires
on page 106).
If you cleaned the corona wires and the Drum
! error is still displayed on the Touchscreen,
then the drum unit is at the end of its life.
Replace the drum unit with a new set.

carefully because it may contain toner. If

wipe or wash it off with cold water at once.

clean the inside of the machine
(see Cleaning and Checking the machine
on page 99).

direct sunlight (or room light for long
periods of time) may damage the drum
