Caution
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe or
wash it off with cold water.
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.
Be sure to seal up the drum unit tightly in a bag so that toner powder does not spill out of the unit.

the cartridge in properly, the blue lock lever is lifted automatically.

up the drum unit assembly.
