IMAGE DRUM LIFE
The life of an image drum depends on a number of factors, including
temperature and humidity, the type of paper used, and the number of
pages per job.
The image drum should last approximately 25,000 pages continuous
printing. This number is approximate because different numbers of
pages are printed each time and the environmental conditions and
the paper type used may vary.
WHEN TO REPLACE THE IMAGE DRUM
