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.
