The error message Toner Low or Prepare New Toner Cartridge indicates that the toner cartridge is approaching the end of its expected life, but the cartridge has not reached its end of life. It is recommended that the toner cartridge continue to be used if the print quality is still good. You should replace the toner cartridge when you feel the print quality is no longer acceptable or when the error message Replace Toner is displayed on the machine's display.

However, it is a good idea to have a new genuine Brother toner cartridge on hand and have it ready for when the Replace Toner status is indicated.

The Brother machine has separate consumables the toner cartridge and the drum unit. Verify you replace only the Toner Cartridge and not the drum unit.

NOTE: We recommend using genuine Brother drum units and toner cartridges. Each Brother laser printer is designed to work at a pre-set temperature that is matched exactly to each of our individual toner formulations. Each Brother component is designed to work with other Brother components to ensure quality and reliability. Although not all non-genuine supplies may cause quality issues, it is possible that some may adversely affect print quality or cause the  machine to malfunction. The Brother limited warranty does not apply to any problem or damage caused by the use of third party drum units, toner cartridges, or toner.
