TROUBLESHOOTING AND ROUTINE MAINTENANCE
Replacing the Drum Unit
The MFC uses a drum unit to create the print images on paper. If the LCD shows
CHANGE DRUM SOON, the drum unit is nearly at the end of its life. Purchase
a new drum unit to replace the current one.
Even if the LCD 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 MFC 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 MFC. (See
Cleaning the
Drum Unit
, page 15-25.)
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 MFC, some internal parts of the machine are
extremely HOT! So please be careful.
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 20 pages 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 cannot guarantee a minimum number of pages that will be printed
by your drum.
