Abstract
Each photoreceptor unit in a multi station printing system has a torque limited drive unit which provides rotational torque to overcome most of, but not all, of the rotational drag forces on the photoreceptors. In this manner, the web contact with the photoreceptor can control the speed of the photoreceptor by overrunning the torque provided by the motor but minimizing the possibly of slip or tearing of the web due to high torque loads imparted to the web by the multiple photoreceptor units of the printer.
