Replacing the drum units

Model Name: DR-241CL 4 pc. Drum Set or single drum units DR-241CL-BK, DR-241CL-CMY
A new drum unit can print approximately 15,000 A4 or Letter size single-sided pages. DR-241CL Drum Set
contains four drum units one Black (DR-241CL-BK) and three Colour (DR-241CL-CMY). DR-241CL-BK
contains one Black drum. DR-241CL-CMY contains one Colour drum.
When a drum reaches the factory-established rotation limit corresponding to the rated page yield, the
products LCD display will advise you to replace the appropriate drum(s). The product will continue to function
once the drum has reached its limit; however, print quality may be severely compromised.
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 will need to replace all of the drums
at once (unless you have replaced an individual drum [DR-241CL-BK for black and DR-241CL-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-241CL).
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 unit
or toner unit.

Drums End Soon
Drums End Soon
The four drum units are nearing the end of their rated life and will require replacement. We recommend you
keep Brother Original drum units ready for installation. Buy a new drum unit set (DR-241CL) and have it ready
before you get a Replace Drums message.
Drum End Soon: X
Drum End Soon: X
If only a specified drum is near the end of its life, the LCD shows the Drum End Soon: X 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-241CL-BK
(for Black) or a DR-241CL-CMY (for either C, M, Y colours) and have it ready before you get a
Replace Drums message. To replace the drum units, see Replacing the drum units on page 120.
