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.
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 
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 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 how much toner you use for the number of pages per 
print job. The estimated drum life is 
up to
20,000 pages. 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.
