Drum life is approximate and may vary by type of
use.
IMPORTANT
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 !
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 82).
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.
Drum End Soon
The drum unit is nearing the end of its rated
life and will require replacement. We
recommend you keep a Brother Original
drum unit ready for installation. Buy a new
drum unit (DR-371CL) and have it ready
before you get a Replace Drum message.
Replace Drum
The drum unit has exceeded its rated life.
Replace the drum unit with a new one. We
recommend a Brother Original drum unit be
installed at this time.
When you replace the drum unit with a new
one, you must reset the drum counter.
Instructions of how to do this can be found in
the box your new drum unit came in.
