CHAPTER SIXTEEN
Replacing the Drum Unit
The machine uses a drum unit to create the print images on paper. If the
screen displays CHANGE DRUM SOON, the drum unit is nearly at the
end of its life. Prepare a new drum unit to replace the current one. You
may need to order one from your Brother dealer.
Even if the display shows CHANGE DRUM SOON, you may be able to
continue to print without replacing the drum unit for a while. However, if
there is a noticeable deterioration in the output print quality even before
CHANGE DRUM SOON is shown, then the drum unit should be
replaced. You should clean the machine when you replace the drum unit.
WARNING
When removing the drum unit, handle carefully because it contains toner.
When you replace the drum unit, you should clean the machine.
The drum unit is a consumable, and it is necessary to replace it
periodically. There are many factors that determine the actual drum life,
such as temperature, humidity, type of paper and toner that you use and
the number of pages per print job, etc. The drum life is estimated at
approximately 20,000 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 cannot 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.
WARNING
After you have just used the machine, some internal parts of the machine
are extremely HOT! So please be careful.
