Brother reset gear for TN2110/TN2120 toner cartridge

OEM supplied Brother TN2120 & TN360 starter cartridges* do not have a reset flag gear installed. The reset gear must be installed in order for the printer to function properly, once the cartridge has been refilled with toner and re installed in the printer.

*A starter cartridge is the cartridge that came free with your printer. If you purchase the cartridge separately from your printer, you will not require this reset gear.
