HEAT SEALED REMANUFACTURED TONER CARTRIDGE

摘要

A remanufactured toner cartridge includes a wall defining a fill hole that is used to refill the cartridge with toner. A patch covers the fill hole, and a heat activated adhesive non-removably attaches the patch to the wall. The fill hole can be formed with a heat knife such that when the heat knife is withdrawn it forms a raised ridge of material extending around the perimeter of the fill hole. The patch is attached to the wall by applying heat and pressure to the patch, which also softens and at least partially flattens the ridge of material surrounding the fill hole such that the patch is substantially flush with the wall upon completion of the operation.
