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.
