Abstract: A reassembled laser toner cartridge and method of manufacture in which the hopper section and roller section of a previously depleted toner cartridge are rewelded together by ultrasonic welding along the length sections after an ancillary energy director strip has been positioned between the sections where the roller section interfaces with the hopper section to provide a laser toner cartridge that has the same or nearly the same specifications as the original equipment manufactured cartridges.

Abstract: A system and process for emptying excess toner from repaired or remanufactured laser printer toner cartridges, for use in both magnetic toner and non-magnetic toner after the cartridge has been assembled and post-assembly tested. The removal of excess toner from the cartridge prevents the cartridge from “sweating”, i.e., leaking toner out from the developing roller section of the cartridge and into the shipping packaging box during shipping and storage.

Abstract: A reassembled laser printer toner cartridge and method of manufacture including a cartridge seal assembly in which the remains of an OEM laser printer toner cartridge's toner hopper pull seal strip(s) is left in position, or a substitute conductive strip is put in the same position to simulate the OEM pull seal strip(s) if the OEM strips have been damaged or are missing in order to enable a repaired or remanufactured cartridge to cooperate with the printer in detecting measuring and displaying the amount of toner consumed from the cartridge and shut the printer down, once the toner cartridge is empty, and a toner cartridge hopper foam seal strip assembly that covers the remnants of the OEM seal strips and provides a seal to prevent leakage of toner from the re-filled toner cartridge.
