Customer Replaceable Units
Identifying the Replaceable Units
There are several consumables on the device that need replenishing or replacing, such as paper,
staples, and customer replaceable units.
1. Toner Cartridge
2. Print Cartridge
The device will display a message on the touch screen when any of the units need to be re-ordered.
This message is a warning that the unit is nearing the end of its life. Only replace the unit when a
message actually instructs you to do so.
WARNING: When replacing consumables do NOT remove the covers or guards that are fas-
tened with screws. You cannot maintain or service any of the parts that are behind these cov-
ers and guards. Do NOT attempt any maintenance procedure that is NOT specifically
described in the documentation supplied for your device.
