Image drum
When to replace image drum
When the drum reaches 90% of its life, a CHG DRUM message is displayed in the control panel LCD. Change the image drum cartridge when the print becomes faint or begins to deteriorate.
Image drum life
The life of an image drum depends on a number of fac- tors, including temperature and humidity, the type of paper used, and the number of pages per job.
The image drum should last about 20,000 pages of A4 size paper (continuous printing). This number is ap- proximate because the environmental conditions and the paper type used may vary.
The first toner cartridge installed in a new image drum has to fill the image drum reservoir and saturate the de- veloping roller with toner. This filling of the image drum reservoir reduces the number of pages produced from the first toner cartridge installed in a new image drum.
