Abstract
Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes a drive gear to transmit rotational force from the printer to the print cartridge. Also, it is desirable to remanufacture print cartridge both to reduce waste and to save resources. Therefore, it may be desirable to provide a drive gear mechanism that is easily replaced or reused when a print cartridge is remanufactured.
