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 25,000 pages
1. The actual
