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 Touchscreen LCD will advise you to replace the applicable 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 must replace all of the drums at once (unless you replaced an individual drum

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,
