Abstract

A media handling device includes a media shingling mechanism having a roller actuator located adjacent an upper portion of a media stack and upstream thereof relative to a predetermined direction of an uppermost sheet from the stack toward a media restraint dam located downstream thereof. The roller actuator undergoes counterclockwise rotation in response to upward moving contact by successive sheets in the upper portion of the stack against a peripheral segment of the roller actuator as the stack is moved vertically upward in a rectilinear direction toward the roller actuator. The counterclockwise rotation of the roller actuator and upward movement of the upper portion of the stack produces a lateral displacement of successive sheets toward the dam so as to produce shingling of successive sheets of the upper portion of the stack relative to one another, providing a uniform inter-page gap between successive sheets.
