ABSTRACT:
A system and a method are provided for sealing a cartridge during a recharging or a refilling of a toner hopper of the cartridge with a toner. The cartridge is filled with the toner through a toner port of the toner hopper. The toner hopper and a shutter drum assembly are separated at a first end of the cartridge. An ultrasonic welder welds a first side at the first end of the cartridge and then welds a second side at the first end of the cartridge. The ultrasonic welder seals the first end of the cartridge by bonding the shutter drum assembly to the toner hopper at the first end of the cartridge. A welding jig maintains alignment of the shutter drum assembly and the toner hopper during reassembly and/or aligns the first side and/or the second side of the cartridge prior to welding by the ultrasonic welder.
