The Drum Unit and Toner Cartridge should be replaced when they
have reached the end of their print life. The Drum Unit prints about
60,000 images.The Toner Cartridge prints about 30,000 images.
The printer will produce a warning on the Operator Panel to inform
the user when the remaining toner amount is low. When the toner
cartridge is empty, there will be a notification on the Operator Panel
and the printer will not continue printing until a new cartridge is
installed.
NOTE
> The possible number of pages that can be printed from a
Toner Cartridge is based on Letter or A4 size paper. The
number of pages that can be actually printed varies
according to the conditions of use.
CAUTION
> Be sure to switch off and unplug the machine before
accessing the interior of the machine for cleaning,
maintenance, or fault clearance. Access to a live
machine’s interior can cause electric shock.
