Abstract
A system for collecting waste toner or developer in an electrophotographic printer includes a waste collection tube for collecting waste toner or developer in an electrophotographic module. An auger transports waste toner or developer from the collection tube through a transport tube to a waste container. A spring has a first end in the collection tube and a second end fixed within the transport tube of the auger. An elbow of the spring rides on the auger and the motion of the auger causes the spring to oscillate in the collection tube.
