The Toner Empty LED will light and the display will show CHANGE TONER and
TONER EMPTY alternately to indicate that the toner is empty. Once this indication
appears, your
machine
will
not
resume
printing
until
you
have
installed
a
new
toner
cartridge.
Replacing the Toner Cartridge
The
machine
can print
approximately
2,200
pages
with
one
toner
cartridge.
When
the
toner cartridge is running low, the display shows CHANGE TONER. The MFC is
supplied
with
a
starter
toner
cartridge
that
must
be
replaced
after
1,000
pages.
NOTE: • Actual page count will vary depending on your average document type.
(i.e.:
standard
letter,
detailed
graphics,
etc.)
• It is recommended that you always keep a new toner cartridge ready for
use for when you see the toner low warning.
• Discard
the
used
toner
cartridge
according
to
local
regulations.
If
you
are
not
sure
of
them,
consult
with
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.
• It is recommended that you clean the machine when you replace the toner
cartridge.
