(see Consumable

After replacing a consumable, you must inform the
machine of its characteristics.

cartridge, must be read by the machine after
installing a new consumable.
The replacement of certain consumables must be
declared on the machine, in the menu

Replacing a toner cartridge
The machine is equipped with a consumable
management system. It indicates when a toner cartridge
is nearing the end of its lifespan. The following messages
will appear on your machine:
•
THE TONER CARTRIDGE X IS NEARLY EMPTY
:
the toner cartridge whose colour is identified by X (C
for cyan, M for magenta, Y for yellow and K for black)
has reached critical threshold (less than 10% remain-
ing in the toner cartridge);
•
THE TONER CARTRIDGE X IS EMPTY - REPLACE
IT
: the toner cartridge is empty.
You can replace the toner cartridge between the time it
has reached critical threshold and when it is empty.
If you do not replace it, the machine will not print.
The procedure for replacing the consumable is included
with the new cartridge.
Once the toner cartridge has been replaced:
1
Insert the smart card provided with the new toner
cartridge into the smart card reader.
2
The machine detects the smart card and displays a
message asking you to confirm the installation of
the new consumable. Press
YES
to confirm.
>
The machine reads the smart card. After reading,
the machine displays a message asking you to re-
move the smart card.
Note
The lens cleaning bar is supplied with the
printer. Store this tool in a safe place so as
not to misplace it.
Note
Always use the smart card provided when
replacing the toner cartridge. The smart
card contains the information required to re-
set the toner level. If you replace the toner
cartridge without using the smart card provi-
ded, the consumable management system
may indicate an error.
