Abstract
An assembly for varying pick normal force in an imaging device includes a spring mounted above a pick mechanism having a pick arm mounted at a first end thereof on a shaft and a pick roller mounted at a second end of the pick arm. A rib projects from the first end of the pick arm towards the spring such that the spring is in contact with the rib to impart a rotational force to the pick arm. The rib on the pick arm changes an amount of deflection of the spring as the angular position of the pick arm changes such that an amount of the rotational force imparted by the spring to the pick arm changes thereby changing an amount of a normal force applied by the pick roller to a media stack.
