Abstract
A pick mechanism, having a clutch mechanism, for picking media sheets from an input tray and introducing them into a paper path of an image forming apparatus. The clutch mechanism comprises a plurality of balls positioned between an inner race and an outer race. Angular backlash between the inner race and the outer race may result in variations in the timing of the media sheets. An algorithm is further included to estimate the pick timing of the media sheets. The algorithm calculates an estimated pick time for a subsequent media sheet that incorporates the known engagement variations of the ball clutch pick mechanism.
