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.
