Drum Stop
We cannot guarantee the print quality.
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.
Replacing the drum unit
IMPORTANT
• While removing the drum unit, handle it
carefully because it may contain toner. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
• Every time you replace the drum unit,
clean the inside of the machine
(see Cleaning and Checking the machine
on page 77).
• DO NOT unpack the new drum unit until
you are ready to install it. Exposure to
direct sunlight (or room light for long
periods of time) may damage the drum
unit.
