How to replace a toner cartridge
1
Open the front cover of the machine.
2
Pull out the used toner cartridge.
3
Take the new toner cartridge out of the
box.
CAUTION
Handle the toner cartridge carefully. If
toner scatters on your hands or clothes,
immediately wipe or wash it off with cold
water.
Note
■
Discard the used toner cartridge
according to local regulations, keeping it
separate from domestic waste.
■
Be sure to seal the toner cartridge tightly
so toner powder does not spill out of the
cartridge. If you have questions, call your
local waste disposal office.

Hold the cartridge level with both hands
and gently rock it from side to side three
to four times to spread the toner evenly
inside the cartridge. Remove the tape
labeled REMOVE and the orange
protective cover from the new toner
cartridge.
Note
■
Wait to unpack the toner cartridge until
immediately before you put it in the
machine. If toner cartridges are left
unpacked for a long time, the toner life will
be shortened.
■
Put the toner cartridge into the machine
immediately after you have removed the
protective cover. To prevent degradation
to the print quality, do not touch the
shaded parts shown.
