CONSUMABLE PARTS

The consumable parts described in this section are parts which are subject to deterioration or
damage and should be replaced at least once during the period of warranty of the product if
any printing quality problem appears.
1.1

Drum Unit

Life expectancy:
NOTE:
* There are many factors that determine the actual drum life, such as temperature, humidity,
type of paper, type of toner used, the number of pages per print job and so on. Under ideal
conditions, the average drum life is estimated at up to 12,000 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 printer should be used only in a
clean, dust-free environment with adequate ventilation.
* Printing with a third-party drum unit may reduce not only the printing 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.
PERIODIC MAINTENANCE
12,000 pages with one drum unit
* At 5% print coverage (A4 or Letter size). The actual number of
printed pages will vary depending on the average type of print job
and paper.
