  • Patent number: 9815649
    Abstract: An imaging device having a door-actuated feed roll separator mechanism. A pair of opposed panels of a frame of the imaging device are positioned parallel to a media path. A feed roll pair in the media path has a drive roll fixedly and rotatably mounted between the panels and a backup roll mounted to a pair of release assemblies that are slidably mounted to the panels. Biasing members bias the backup roll into contact with the drive roll forming a feed nip. A door pivotally mounted along a bottom end to the frame substantially covers the media path. A pair of tethers connect the pair of release assemblies to the door. With the door lowered, its weight applies a release force to the backup roll separating it from the drive roll to allow for easier removal of a media sheet jammed in the feed nip.
