Abstract

A removable media tray assembly for an image forming device according to one embodiment includes a media tray having a bottom surface and a front wall extending upward from the bottom surface. A bottom surface defines a media storage location for storing a stack of media sheets. The assembly includes a housing having an opening therein to receive the media tray. A magnet and a plate provide a latching force FL greater than a pick motor stall force keeping the media tray in a closed position during media picking. A handle assembly including a finger bar and a pivoting link is mounted to the front wall. With the media tray being held closed by the latching force, a user-supplied actuation force FA that is less than 22.2 N applied to the finger bar, pivots the link which acts as a force multiplier providing a release force exceeding the latching force.
