A new drum unit can print approximately 
12,000 Letter or A4 size single-sided pages.

• 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 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 machine should be 
used only in a clean, dust-free 
environment with adequate ventilation.

• Printing with a non-Brother drum unit may 

reduce not only the print quality but also 
the quality and life of the machine itself. 
Warranty coverage does not apply to 
problems caused by the use of a 
non-Brother drum unit.
