REPLACING THE DRUM UNIT
The printer uses a drum unit to create the print images on paper. If the
Drum
lamp is on, it
indicates the drum unit is nearly at the end of its life. We recommend you prepare a new drum
unit to replace the current one. Even if the
Drum
lamp is on, you may be able to continue to
print without replacing the drum unit for a while. If there is a noticeable deterioration in the
output print quality even before the
Drum
lamp lights, then the drum unit should be replaced.

Note
The drum unit is a consumable, and it is necessary to replace it periodically.
There are many factors that determine the actual drum life, such as temperature,
humidity, type of paper and toner that you use, the number of pages per print job, etc..
The drum life is estimated at approximately 20,000 pages at 20 pages per job and 8,000
pages at 1 page per job. The actual number of pages that your drum will print may be
significantly less than these estimates. 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, and the product should only be
used in a clean, dust-free environment with adequate ventilation.
Follow these steps to replace the drum unit:
1
Open the top cover towards you. Remove
the drum unit by holding each side of the
drum and gently lifting the drum forwards
towards you.
✒
Note
It is recommended to put the drum unit on a
piece of disposable paper or cloth in case of
accidental toner spill or scatter.
