Abstract

Disclosed in the drawing is a cleaning system generally indicated by reference character 10. It is used for removing toner particles from a charge retentive surface 12. To this end, the system 10 comprises a blade 14 which removes the toner from the surface 12 whereupon it falls into a toner sump 16. Disposed in the bottom of the sump is an auger 18 which serves to move the toner to one end of the sump from where it can be either removed or further transported for subsequent removal. In some prior art devices, the toner tends to bridge over the auger. In other words, it forms a pile in the bottom of the sump, such that it covers the top of the auger. In overcoming the foregoing problem, there is provided a shaft 20 which carries a plurality of feelers 22 rotatably supported within the confines of the auger. The feelers extend beyond the outer circumference of the auger such that they can be rotated through the toner to thereby preclude bridging.
