Abstract: A media restraint for a removable media tray and slidably operable without the use of a pinching force. The media restraint slidably positionable on a track in a removable media tray and is operable without pinching. A pair of pivoting latching cams are used to engage the media restraint to the track and have serrated portions pivotally mounted to a bottom of the media restraint. The media restraint is operable by a finger of the user applying a downward force to an actuator that spreads two cam plates apart which in turn pivot the pair of latching cams to release the media restraint from the track and allowing it to be moved along the track. Upon removal of the downward force, a biasing member lifts the actuator to bring the two cam plates back to their first positions thereby pivoting the pair of latching cams back to reengage with the track.

Abstract: A removable media tray for an imaging device having a rear media restraint coupled to a media length sensing system. A rear media restraint, slideably latchable to a track in the tray, has a rack that engages with a gear train that drives an encoder gear. As the rear media restraint is adjusted for different media lengths, the rack and gear train rotate the encoder gear. The encoder gear has a plurality of encoder tracks each track having a unique binary pattern. A sensor array of a plurality of sensors corresponding to the plurality of encoder tracks has a plurality of outputs that combine to form a digital signal fed to a controller in the imaging device allowing the controller to determine a media length based in the position of the rear media restraint.

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.
