This gear is only needed if you are refilling STARTER* cartridges for the Brother TN-221 / TN-225, 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-221 / TN-225 starter cartridge (any color) in order for the printer to function properly once the cartridge has been refilled and re-installed in the printer.
* A starter cartridge is the cartridge that ships free with your printer. If you purchase the cartridge separatley, you will not require this gear.
Each kit contains: 1 reset gear + instructions for assembly (easy to do!)
