A new drum unit can print approximately 12,000 A4 or Letter size single-sided pages at 1 per/ job.

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 approximately 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 a third-party drum unit.

The 

Drum

 LED will turn on for 2 seconds and off for 3 seconds and repeats this pattern.

If the LED shows the message, 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.
