Abstract
A scuffer wheel drives a copy sheet into a registration corner on a tray of a printing machine. The vibration and hop of the scuffer wheel is damped by having the periphery of the scuffer wheel engage a leaf spring mounted over a slot in a thin plate mounted on the tray. This prevents sheet migration and misalignment of the sheets of the stack with respect to one another.
