Replacing the drum unit

Order No. DR-420

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

Note

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

A

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.
