Discard the used drum unit according to local regulations. Be sure to seal the drum
unit tightly so toner powder does not spill out of the unit. When discarding used
drum units, keep them separate from domestic rubbish.
• If an unpacked drum unit is subjected to excessive direct sunlight or room
light, the unit may be damaged.
• Handle the toner cartridge and the drum unit carefully because they
contain toner. If toner scatters and your hands or clothes get dirty,
immediately wipe or wash with cold water.
• Do not touch the scanner window with your fingers.
