Image Drum Yield

The life of an image drum depends on a number of factors, including temperature and humidity, the type of paper you use, and the number of pages per job. The image drum cartridge should last about 20,000 pages for continuous printing, up to 14,000 pages at 3 pages per job, and about 9,000 pages at 1 page per job.
