BELT TRACKING SYSTEM(Cont'd)

The use of belts for photoreceptors, flexible development electrodes, donors for touchdown developement, and pa er handling components has always met

complex and expensive; edge guides wear and fray the belt edges; sprocket holes wear and stretch in time; and edge bead methods that keep the belt under tension (instead of pushing on the edge) still have problems of belt wrinkling if one edge tends to drive slightly faster than the other.

In FIGS. 1 - 4, a belt tracking system is disclosed that offers the positive drive advantages of sprocket holes in the belt, yet also provides a more robust, enduring method of tracking. In the system, the drive pulley, along with idler pulleys, etc., have holes instead of teeth, and the belt has teeth instead of holes.

A belt 10 into which holes 12 are punched near each edge is shown in FIG. 1. A tooth 15 is inserted into each hole, each tooth being supported on a st...
