until immediately before installing
it. Place the old drum unit into the
aluminum bag and discard it

NOTE: • Discard the used drum unit according to local regulations. If you are not
sure of them, consult with Brother Customer Service. 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 separated from domestic garbage.
• We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering the toner.
