Drum !
The corona wires are dirty. Clean the corona
wires in the four drum units (see Cleaning the
corona wires on page 101).
If you cleaned the corona wires and the
Drum ! error is still displayed on the
Touchscreen, then the drum unit is at the end
of its life. Replace the drum units with a new
set.
Drum End SoonX
If only a specified drum is near the end of its
life, the Touchscreen shows the
Drum End SoonX message. The X indicates
the drum unit colour that is near the end of its
life. (BK=Black, C=Cyan, M=Magenta,
Y=Yellow ). We recommend you keep Brother
Original drum units ready for installation. Buy
a new drum unit DR-261CL-BK (for Black) or
a DR-261CL-CMY (for either C, M, Y colour)
and have it ready before you get a
Replace DrumX message.
Replace DrumX
If only a specified drum needs to be replaced,
the Touchscreen shows the
Replace DrumX message. The X indicates
the drum unit colour that you must replace.
(BK=Black, C=Cyan, M=Magenta, Y=Yellow )
The drum unit has exceeded its rated life.
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.
