This printer can print up to 30,000 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.
CHANGE DRUM SOON message
The printer uses a drum unit to create the print images on paper. If the LCD shows CHANGE DRUM
SOON, 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.
Replacing the drum unit
Caution
While removing the drum unit, handle it carefully because it may contain toner.
Follow these steps to replace the drum unit. You can also view the drum unit replacement method in the
instructional video on the supplied CD-ROM:
■
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 30,000 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.
We recommend that you clean the printer when you replace the drum unit. See Cleaning on page
5-14.
