This printer can print approximately 20,000 pages
*1
with one drum unit.
*1
At 5% print coverage (A4-Letter size). The actual number of printed pages
may vary depending on the average type of print job and paper.
Note
y 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, etc. Under ideal conditions, the average drum life is estimated at
approximately 20,000 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.
y For best performance, use only genuine Brother toner. The printer should be
used only in a clean, dust-free environment with adequate ventilation.
y Printing with a 3rd 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 3rd party drum unit.
