Replacing the drum unit
B
The machine uses a drum unit to create print 
images on paper. If the LCD shows 
Drum End Soon
, the drum unit is near the
end of its life and it is time to buy a new one.
Even if the LCD shows 
Drum End 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 
Drum End Soon
appears), then the drum
unit should be replaced. You should clean the 
machine when you replace the drum unit.

Cleaning the laser scanner window
CAUTION
While removing the drum unit, handle it 
carefully because it may contain toner. If 
toner scatters on your hands or clothes, 
wipe or wash it off with cold water at once.
Note
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 
approximately 12,000 pages
. The actual
number of pages your drum will print may 
be significantly less than this estimate. 
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.
