MAINTENANCE
Replacing the Toner Cartridge
The machine can print up to 6,000 pages using a high yield toner cartridge (TN-6600). When the
toner cartridge is running low, the display shows CHANGE TONER. The machine is supplied with
a standard toner cartridge (TN-6300) that must be replaced after approximately 3,000 pages. Actual
page count will vary depending on your average document type.
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 with
Brother dealer for 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.
Toner Empty Indicator
When the toner cartridge is running low, the display shows CHANGE TONER and the Toner
Empty LED on the control panel flashes on and off to indicate the toner is low.
The Toner Empty LED light stays on and the display shows TONER EMPTY to indicate that the
toner is empty. Once this indication appears, the machine will not resume printing until you have
installed a new toner cartridge.
Steps for Replacing Toner Cartridge
DO NOT refill the toner cartridges. Attempting to use refilled toner cartridges
or the use of incompatible toners, may cause damage to your product. Any
such damages will not be covered by warranty. Warranty coverage does not
apply to problems caused by the use of 3rd party consumables. We can only
recommend the use of genuine Brother consumables.
After you have just used the machine, some internal parts of the machine
will be extremely HOT! Never touch the shaded parts shown in the
illustration below.
