Abstract:
1. A method of making a remanufactured toner cartridge comprising: a. providing a used toner cartridge roller section made of a first organopolymeric material, separated from a first previously used toner cartridge, said roller section having some of its original organopolymeric material removed during disassembly and said roller section having a flat joining surface; b. providing a used toner cartridge hopper section made of said organopolymeric material, separated from a second previously used toner cartridge, having a longitudinal axis, having a cavity extending along said longitudinal axis, said hopper section having some of its original organopolymeric material removed during disassembly and said roller section having a flat joining surface; c. filling said hopper section with toner to make a filled hopper section; d. attaching a pull seal to said flat joining surface of said filled hopper section; e. attaching a hopper port seal to said hopper section; f. providing two strips of ancillary energy director made of said organopolymeric material and each of said strips having a thickness; g. placing said strips along the longitudinal axis of the hopper, in physical contact with the hopper section, in physical contact with the roller section and between said flat joining surface of said hopper section and said flat joining surface of said roller section; and, h. welding said hopper section and said roller section together by ultrasonically melting the two strips of ancillary energy director and fusing the hopper section to the roller section to form said remanufactured toner cartridge.
