Proposed is an polygon drive coupling that facilitates a smooth motion profile for application in tri-level xerography. Tri-level xerography is more sensitive to motion quality defects than conventional xerography. This is especially true for the color portion of an image where motion quality is defined by photoreceptor speed variations and structural vibrations at the ROS. A ty ical motion quality specification may be equal to approximately 0.25% o P the velocity variation at the photoreceptor surface.
