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 translateably mounted between the panels. A pair of cam followers are rotatably mounted to the backup roll. The backup roll is biased against 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 door-mounted, spring-biased actuators engage with the pair of cam followers. With the door lowered, the cam followers rotate with a camming surface thereon contacting the drive roll, translating the backup roll away from the drive roll and opening the feed nip to allow for removal of jammed media.
