A media accumulator-ejector for use with an imaging apparatus. Rotatable upper and lower roll assemblies are located above and below a media accumulation zone comprised of an accumulation plate and positioned to receive media exiting an imaging device. The roll assemblies are moveable like jaws between an open position where media can accumulate on the accumulation plate without interference with the roll assemblies and a clamping position where the accumulated media is grasped by the upper and lower roll assemblies. The upper and lower roll assemblies are then rotated to eject the accumulated media from the accumulation plate. The upper and lower roll assemblies can also grasp and continuously eject individual sheets of media at a predetermined process speed.

A print media feeder apparatus suitable for use in an image-forming device is provided. The apparatus comprises an elevator tray holding a stack of print media connected to a housing by a transmission system. The housing comprises a hoist drum that is connected to one end of a shaft for connecting the housing to the transmission system. A spring enclosure encasing a spring is fixed on the other end of the shaft. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft. This results in the displacement of the spring and a corresponding vertical movement of the elevator tray to position the print media at the desired feeding level.
