REPLACING TONER CARTRIDGE AND DRUM UNIT
12-2
MFC 4450/OP-US-5.0
Maintenance
Follow these steps to replace the toner cartridge:
1)
1) Turn off the power switch and
unplug the power cord.
2)
2) Open the top cover. To remove the
drum unit, hold each side of the
drum by its handles and gently lift
the drum forward toward you.
NOTE
• Make sure the top cover is
completely open, by lifting it until
the latch clicks into place.
• We recommend you place the
drum unit on a drop cloth or large
piece of disposable paper to avoid
spilling and scattering the toner.
