Replacing the Drum Unit
The machine uses a drum unit to create the print images on paper. If the display shows CHANGE
DRUM, it indicates the drum unit is nearly at the end of its life. We recommend you prepare a
new drum unit to replace the current one. Even if the display shows CHANGE DRUM, you may
be able to continue to print without replacing the drum unit for a while. If there is a noticeable
deterioration in the output print quality even before CHANGE DRUM is shown, then the drum
xmit should be replaced.
WARNING
When removing the drum unit, handle carefully because it contains toner.
You should clean the machine when you replace the drum unit. See page 119.
NOTE: The drum imit is a consumable, and it is necessary to replace it periodically.
The drum unit is rated at approximately 20,000 pages. There are many factors that
determine the actual drum life, such as temperature, humidity, 1зфе of paper and toner
that you use and the number of pages per print iob, etc... The drum life is estimated at
approximately 20,000 pages at 20 page per job and 8,000 pages at 1 page per job. The
actual number of pages your drum will print may be significantly less than these
estimates. Because we have no control over the many factors that determine the actual
drum life, we can not guarantee a minimum number of pages that will be printed by
your drum.
For best performance, use only genuine Brother toner, and the product should be used
only in a clean, dust-free environment with adequate ventilation.
Follow these steps to replace the drum unit:
1) Turn off the power switch or unplug the power cord.
2) Open the top cover.
