IMPORTANT
For best performance, use only Genuine
Brother drum units and Genuine Brother
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 printer itself. Warranty coverage may
not apply to problems caused by the use
of a third-party drum unit or toner unit.
Note
If only the specified drum needs to be
replaced, the LCD shows the
Replace Drum(X) message. (X)
indicates the drum unit colour that you
need to replace. ((K)=Black, (Y)=Yellow,
(M)=Magenta, (C)=Cyan). During the
normal lifespan of a drum kit the Replace
Drum (X) message will not appear. The
message will only refer to a specific drum
if a single unit has been replaced
previously due to damage or error.

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 printer. (See
Routine maintenance on page 142.)
