NOTE
• 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 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/
