CHAPTER FIFTEEN
Follow these steps to replace the drum unit:
1
Open the front cover.
2
Remove the old drum unit. Place the drum unit on a drop cloth or
large piece of disposable paper to avoid spilling and scattering the
toner.
3
Pull the toner cartridge out of the drum unit assembly while holding
down the lock lever with your right hand. For more information, see
“Replacing the Toner Cartridge” in this chapter.
Lock Lever
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.
4
Unpack the new drum unit immediately before installing it. Place the
old drum unit into the aluminium bag and discard it according to
local regulations.
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 finger.
