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 will advise you to
replace the drum. The product will continue to function; however, print quality may not be optimal.
• If an unpacked drum unit is placed in direct sunlight (or room light for long periods of time), the unit may
be damaged.
• 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 30,000 pages based on 1 page per job and 50,000 pages based on 3 pages per job [A4/
letter simplex pages]. The number of pages may be affected due to a variety of factors including but not
limited to media type and media size.
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.
