Every time you replace the drum unit, you should clean the inside of the printer. see Cleaning

■
There are many factors that determine the actual drum life, such as the temperature, humidity,
type of paper, type of toner used, number of pages per print job and so on. Under ideal
conditions, the average drum life is estimated at up to 20,000 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.
■
Printing with a third-party drum unit may reduce not only the print quality but also the quality and
life of the printer itself. Warranty coverage does not apply to problems caused by the use of
third-party drum unit.
■
For best performance, use only genuine Brother drum and toner. The printer should be used
only in a clean, dust-free environment with adequate ventilation.
