Routine Maintenance Replacing the drum units 4 Order No. DR-221CL 4 pc. Drum Set or single drum units DR-221CL-BK, DR-221CL-CMY A new drum unit can print approximately 15,000 Letter or A4 size single-sided pages. DR-221CL Drum Set contains four drum units one Black (DR-221CL-BK) and three Color (DR-221CL-CMY). DR-221CL-BK contains one Black drum. DR-221CL-CMY contains one Color drum. Drum wear and tear occurs due to use and rotation of the drum and interaction with paper, toner and other materials in the paper path. In designing this product, Brother decided to use the number of rotations of the drum as a reasonable determinant of the drum life. When a drum reaches the factory-established rotation limit corresponding to the rated page yield, the product's LCD display will advise you to replace the applicable 4 drum(s). The product will continue to function; however, print quality may not be optimal. 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-221CL-BK for black and DR-221CL-CMY for Color] for reasons other than reaching its rated life). For your convenience, Brother sells the drum units as a set of four (DR-221CL). NOTE • There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at approximately 15,000 pages. The actual number of pages that your drum will print may be significantly less than this estimate. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum. • For best performance, use only genuine Brother toner. The machine should be used only in a clean, dust-free environment with adequate ventilation. • Printing with a non-Brother drum unit may reduce not only the print quality but also the quality and life of the machine itself. Warranty coverage does not apply to problems caused by the use of a non-Brother drum unit. Drum! 4 Drum! The corona wires have become dirty. Clean the corona wires in the 4 drum units (see Cleaning the corona wires on page 143). Drums End Soon 4 Drums End Soon The four drum units are nearing the end of their rated life and will require replacement. We recommend you keep genuine Brother drum units ready for installation. Buy a new drum unit set (DR-221CL) and have it ready before you get a Replace Drums message. 119

A new drum unit can print approximately 15,000 Letter or A4 size single-sided pages. DR-221CL Drum Set
contains four drum units one Black (DR-221CL-BK) and three Color (DR-221CL-CMY). DR-221CL-BK
contains one Black drum. DR-221CL-CMY contains one Color drum.
Drum wear and tear occurs due to use and rotation of the drum and interaction with paper, toner and other

There are many factors that determine the actual drum life, such as the temperature, humidity, type of
paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at
approximately 15,000 pages. The actual number of pages that your drum will print may be significantly

For best performance, use only genuine Brother toner. The machine should be used only in a clean,
dust-free environment with adequate ventilation.

Printing with a non-Brother drum unit may reduce not only the print quality but also the quality and life of
the machine itself. Warranty coverage does not apply to problems caused by the use of a non-Brother
drum unit.
