As the drums rotate in unison during the
various stages of operation (regardless of
whether toner is deposited on the page) and
because damage to a single drum unit is not
likely, you must replace all of the drums at
once (unless you replaced an individual drum
[DR-251CL-BK / DR-261CL-BK for Black and
DR-251CL-CMY / DR-261CL-CMY for
Colour] for reasons other than reaching its
rated life). For your convenience, Brother
sells the drum units as a set of four
(DR-251CL / DR-261CL).
IMPORTANT
For best performance, use a Brother
Original drum unit and Brother Original
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 machine itself. Warranty coverage
may not apply to problems caused by the
use of a third-party drum or toner unit.
Drum ! A
The corona wires are dirty. Clean the corona
wires in the four drum units (see Cleaning the
corona wires on page 107).
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 A
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-251CL-BK /
DR-261CL-BK (for Black) or a
DR-251CL-CMY / DR-261CL-CMY (for either
C, M, Y colour) and have it ready before you
get a Replace DrumX message.
Replace DrumX A
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.
