Drum unit

This printer can print up to 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.

Note

•

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 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 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.

Change Drum message

If the LED shows the message below, it means the drum unit is near the end of its life. We recommend that 
you replace the drum unit with a new one before there is a noticeable deterioration in the print quality.

CAUTION

•

While removing the drum unit, handle it carefully because it may contain toner.

•

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