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.
