Drum unit4
A new drum unit can print approximately 12,000 A4 or Letter size single-sided pages at 1 page / job.
Note
• There are many factors that determine the actual drum life, such as the temperature, humidity, type of 
paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average 
drum life is estimated at approximately 12,000 pages. The actual number of pages that your drum will print 
may be significantly less than this estimate....
