Abstract
A pick mechanism including a pick roller, a pick arm supporting the pick roller and an actuation system adapted to move the pick arm from an idle position to a pick position and impart additional normal force to the pick roller. The magnitude of the additional normal force, which is greatest when the tray is full, decreases as the size of the stack in the tray decreases.
