Replacing a print unit
The machine is equipped with a consumable
management system. It indicates when a print unit is
nearing the end of its lifespan. The following messages
will appear on your machine:
• THE PRINT UNIT X IS NEARING THE END OF ITS
LIFE: the print unit 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 print unit);
• THE PRINT UNIT X IS AT THE END OF ITS LIFE:
REPLACE IT: the print unit is empty.
You can replace the print unit 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 print unit.
Replacing the waste toner bottle
Replace the waste toner bottle when the machine
displays the message THE WASTE TONER BOTTLE IS
AT THE END OF ITS LIFE: REPLACE IT. If you do not
replace it or declare its replacement, the machine will not
print. After replacing, you must declare the replacement of
this consumable.

er bottle.
