Abstract
A toner-filling device that transports a toner mass from a hopper to a cartridge. A porous tube is used during the filling operation to remove air from or supply air to the toner. This porous tube will operate at various depths of toner to more completely remove air from or supply air to the toner. An auger is used to transport the toner, and the porous tube extends through the auger beyond the lowest end of the auger.
