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 operator panel LCD. Change the image drum
when the print becomes faint or begins to deteriorate.
Replacing the image drum .
WARNING
> Never expose the image drum to an open flame.
It can cause an explosion and you can be
burned.
> Be sure to switch off and unplug the machine
before accessing the interior of a machine for
cleaning, maintenance or fault clearance. Access
to a live machine’s interior can cause electric
shock.
NOTE
> 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 B431 model has been illustrated below. The
principles are the same for the B411 printer.
