REQUIRED: Brother TN-420 / TN-450 reset gear (sold separately) - required for Brother TN-420 / TN-450 STARTER CARTRIDGES. A starter cartridge is the cartridge that ships free with your printer. If you purchase the cartridge separately to the printer, you will not require this gear. Since the starter cartridges don't always have this reset gear installed, the printer displays a "toner life end" message if no reset gear is detected. A reset gear must be installed on any used TN-420 / TN-450 starter cartridge in order for the printer to function properly once the cartridge has been refilled.
