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 the drum reaches 90% of its life, a CHANGE DRUM
message is displayed in the printer Status Monitor. Also, the Error
LED indicator blinks fast when the image drum requires
changing. Change the image drum when the print becomes faint
or begins to deteriorate.
WARNING!
If the printer has been powered on, the fuser may be
hot. This area is clearly labelled. Do not touch.
