Drum unit
CHANGE DRUM SOON message
The printer uses a drum unit to create the print images on paper. If
the LCD shows CHANGE DRUM SOON, it means the drum unit is
near the end of its life. We recommend that you replace the drum
unit with a new one before there is a noticeable deterioration in the
print quality.
Replacing the drum unit
Every time you replace the drum unit, you should clean the inside of
the printer. For more information, see Cleaning in this chapter.
This printer can print up to 40,000 pages

with one drum unit.

At 5 % coverage print (A4 or Letter size). The actual number of
printed pages will vary depending on the average type of print job
and paper.
■ There are many factors that determine the actual drum life,
such as temperature, humidity, type of paper, type of toner
used, the number of pages per print job and so on. Under
ideal conditions, the average drum life is estimated at up to
40,000 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
printer should be used only in a clean, dust-free
environment with adequate ventilation.
