Method and apparatus for reassembling a toner cartridge
In the toner cartridge recycling and remanufacturing industry, used xerographic toner cartridges are reconditioned and refilled with toner. There are various types and models of toner cartridges, each having unique physical properties. The present invention is directed to the reassembling of toner cartridges that may not have sufficient securing surfaces to allow the cartridge to be physically held together using an external securing device. The present invention will also enable the toner cartridges to be more efficiently remanufactured by allowing a quick connect or disconnect during the assembly or disassembly process.
