cartridge out of the drum unit.
Note
• Be sure to seal up the drum unit tightly in a bag so that
toner powder does not spill out of the unit.
• Discard the used drum unit according to local
regulations, keeping it separate from domestic waste.
If you have questions, call your local waste disposal
office.

you hear it lock into place. If you put the cartridge in

printer.
CAUTION
Handle the toner cartridge carefully. If toner scatters on
your hands or clothes, immediately wipe or wash it off with
cold water.
CAUTION
Wait to unpack a drum unit until immediately before you put it in the printer. Exposure to direct sunlight or
room light may damage the drum unit.
CAUTION
Make sure you insert the toner cartridge properly, or it may
separate from the drum unit.
