Image Drum Life; When To Replace The Image Drum; Replacing The Image Drum - Oki B4100 User Manual

IMAGE 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 TO REPLACE THE IMAGE DRUM

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.

REPLACING THE IMAGE DRUM

It is recommended that you change the toner cartridge and clean the
LED array at the same time as you change the image drum.
The green image drum surface at the base of the cartridge is very
delicate and light sensitive. Do not touch it and do not expose it to
normal room light for more than 5 minutes. If the drum unit needs to be
out of the printer for longer than this, please wrap the cartridge inside
a black plastic bag to keep it away from light. Never expose the drum
to direct sunlight or very bright room lighting. Always hold the image
drum unit by the ends or from the top.
