Abstract
A method for remanufacturing toner cartridges includes the use of a plurality of machine screw inserts. Each of a plurality of screw holes of a toner cartridge shell is tapped to create new threading within the plurality of screw holes. The plurality of machine screw inserts is positioned into the plurality of screw holes in order to reinforce the plurality of screw holes, wherein each of the plurality of machine screw inserts has a threaded outer surface and a threaded inner surface. The plurality of machine screw inserts provides a durable interface with a plurality of screws that reduces the chance of failure of the plurality of screws as the plurality of screws is positioned within the plurality of screw holes. An adhesive is applied to each of the plurality of machine screw inserts in order to secure the plurality of machine screw inserts within the plurality of screw holes.
