Title of Invention

[0001] Manufacturing process of toner cartridges for laser printers by improvement and adjustment of the organic photo conductor and cutting tool therefor.

Background Art or Relevant Technical

[0003] Toner cartridges for laser printers nowadays are rather convenient and simple to use. The quality of the printed documents or articles is also relatively better than other types of toner cartridges. Current toner cartridges for laser printers have various characteristics and properties regarding the model and brand of the printer. As a result, the demand for toner cartridges has increased drastically. An impact that follows is the increase of waste as scrape of materials or parts that are the components of toner cartridges.

[0004] Therefore, there is the need to recycle toner cartridges for laser printers by disassembly and reassembly. The disassembly must rely on compliance of the engineering and manufacturing process and their specified regulations. Engineering tools are applied in the disassembly to achieve the maximum efficiency and a comparable quality between toner cartridge sand recycled toner cartridges. In addition, the production must use materials or parts from the used toner cartridges in order to further reduce waste of scrape materials or of parts of the toner cartridges as much as possible. The recycling process of the used toner cartridges for laser printers has a assembly that is clearly referenced by specified regulations, e. g. given in US 8,644,732. Therefore, the organic photo conductor of a used toner cartridge must be inspected and tested comprehensively and accurately according to all specified regulations. In case that the organic photo conductor failed the inspections and tests or has any problem, an adjustment to use organic photo conductors from other toner cartridge models is required. If the organic photo conductor from other toner cartridge models can be applied in the toner cartridge production, this can reduce the waste from the organic photo conductor by 80% of the total organic photo conductors that passed the inspection and test. Nevertheless, this depends on the manufacturing procedures, which are based on the compliance with specified regulations, and must use the materials or parts from the old toner cartridge.

[0010] Assembly of a contact gear, also called drive gear, of a ready to use printer to one side of the cylinder of the organic photo conductor by fastening.

[0011] Attachment of a coupling member of the printer. This can be done by attaching the coupling member of the ready to use printer with the other side of the cylinder of the organic photo conductor by secure bonding, and thus obtaining a recycled used organic photo conductor.
