Replacing the drum unit
The MFC uses a drum unit to create print images on paper. If the
LCD shows Change Drum Soon , the drum unit is near the end of
its life and it is time to purchase a new one (DR-3000).
Even if the LCD shows Change Drum Soon , you may be able to
continue printing without having to replace the drum unit for a while.
However, if there is a noticeable deterioration in the output print
quality (even before Change Drum Soon appears), then the drum
unit should be replaced. You should clean the MFC when you
replace the drum unit. (See Cleaning the drum unit on page 12-24.)
Caution
When removing the drum unit, handle it carefully because it contains
toner. If toner scatters and your hands or clothes get dirty,
immediately wipe or wash with cold water.
WARNING
Just after you have used the MFC, some internal parts of the MFC
are extremely HOT! So, never touch the shaded parts shown in the
illustration.
