Display Toner Empty LED
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 machine 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 rubbish.
• It is recommended that you clean the machine when you replace the toner cartridge.
