A drive shaft grounding device for use in paper handling subsystems, particularly document feeders or paper drive shafts in paper paths, of electrophotographic printing and copying machines is disclosed. As shown in the Figures, the device comprises a grounded metal cap 10 that fits over the ends of each drive shaft 1 to provide sufficient electrical grounding to prevent static charge accumulation. The cap consists of a flexible rubber seal 2 to keep dust out, a recess 3 to accommodate the end of the drive shaft, an outside conductive metallic casing 4 and a mounting aperture 5 for securing the shaft to a support frame. A similar shaft electrical grounding device was disclosed by Scarlata in the Xerox Disclosure Journal, Vol. 14, No. 5, September/October 1989.
