Image Drum Cartridge Life

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 9,000 pages at one page per job, 14,000 pages at three pages per job and 20,000 pages at fifteen pages per job. These numbers are approximate, since you do not print the same number of pages each time, and environmental conditions and paper type used may vary.

The image drum is fragile. To avoid damage to the new drum, take these precautions while handling the new image drum cartridge:

• Do not touch the green drum surface.

• Do not set the cartridge down on anything that might scratch the surface of the drum.

• Do not expose the drum to direct sunlight and do not expose it to room light for more than 5 minutes. Leave it in the package until you are ready to install it into the printer.
