Replacing the drum unit

Model name: DR-3300
A new drum unit can print approximately
30,000 A4 or Letter size single-sided pages.
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 or toner unit.

corona wire in the drum unit. (See Cleaning
the corona wire uu page 80.)
If you cleaned the corona wire and
Drum Error was not cleared then the drum
unit is at the end of its life. Replace the drum
unit with a new one.
