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 17,000 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.
