Replacing the Toner Cartridge

The machine can print up to 6,000 pages using a high yield toner
cartridge. When the toner cartridge is running low, the display shows
TONER LOW. The machine is supplied with a standard toner cartridge
that must be replaced after approximately 3,000 pages. Actual page count
will vary depending on your average document type (i.e., standard letter,
detailed graphics).
It is a good idea to keep a new toner cartridge ready for use when you see
the toner low warning.
Discard the used toner cartridge according to local regulations. If you are
not sure of them, consult Brother Customer Service. Be sure to seal the
toner cartridge tightly so toner powder does not spill out of the cartridge.
When discarding used toner cartridges, keep them separate from domestic
garbage.
We recommend that you clean the machine when you replace the toner
cartridge.

Toner Empty Indicator

When the toner cartridge is running low, the display shows TONER LOW
and the Toner Empty icon on the control panel flashes on and off to
indicate the toner is low.
The Toner Empty icon appears and the display shows TONER EMPTY.
Once this icon appears, your machine will not resume printing until you
install a new toner cartridge.
