Replacing The Drum Unit - Brother MFC-4800 User Manual

Replacing the Drum Unit

The FAX/MFC uses a drum unit to create the print images on paper. If the LCD
shows CHANGE DRUM
Purchase a new drum unit to replace the used one.
Even if the LCD shows
to print without replacing the drum unit for a while. However, if there is a
noticeable deterioration in print quality even before
is shown, then the drum unit should be replaced. You should clean the printer
when you replace the drum unit.
Caution
When removing the drum unit, handle it carefully because it contains toner.
When you replace the drum unit, you should clean the FAX/MFC.
The drum unit is a consumable item, 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 continuous printing 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 cannot guarantee a minimum number of pages that will be
printed by your drum.
For best performance, use only a genuine Brother toner cartridge. The product
should be used only in a clean, dust-free environment with adequate ventilation.
WARNING
Just after you have used the FAX/MFC, some internal parts of the machine are
extremely HOT! So please be careful.
