Toner Reclaiming System

This description relates to apparatus for transporting scavenged toner from a remote cleaning station back to the developer sump.

The general configuration of the system is shown in Fig. 1. Toner is removed from the photoconductor belt 1 by the magnetic brush cleaning station 2 and passed onto the mixing bin 3 by the cyclone operator 4. Carrier beads are conveyed from the developer unit 5 through one section of the two-sectioned nylon tube 6 into the mixing bin 3. The bin 3 is constructed to provide maximum interaction between the carrier particles and the toner. The mixture falls by gravity into the return path of the tube 6 and is returned to the developer sump.

Fig. 2 shows the detail to enable the movement of the carrier and the toner within the tube 6. The tube 6 is constructed into two sections 7 and 8. Within section 7, there is a continually driven chain of moving magnets 9. The other section 8 contains the carrier and toner, which is moved through section 8 through the interaction with the moving magnets 9 in the tube 7. As the carrier and toner is moving through the return path of the tube 6 from the mixing bin 3, it is deposited in the developer sump, as shown, for re-use in the processing system.
