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 rubbish.
• We recommend you place the drum unit on a drop cloth or large piece of disposable
paper to avoid spilling and scattering the toner.
