  • 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 75,000 pages based on three pages per job and 45,000 pages based on one page per job (A4/Letter single-sided pages). The number of pages may be affected by 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.

  • The machine should be used only in a clean, dust-free environment with adequate ventilation.

    We recommend using genuine Brother supplies to ensure stable print quality and performance. Although not all non-genuine supplies may cause quality issues, it is possible that some may adversely affect print quality or cause machine malfunction. Brother may charge for repairing your machine if it is proven that non-genuine supplies caused the damage, even if the machine is still covered by the warranty.
