Claim:
A removable input tray assembly for an image forming device, comprising: a media tray having a bottom surface and a wall extending upward from the bottom surface, the bottom surface defining a media storage location for storing a stack of media sheets; a housing having an opening therein to receive the media tray; an inclined media dam formed in the wall having a media contact surface for directing media advanced from the media storage location; a channel provided in the wall extending the height of the wall for directing media passing therethrough having a front wall, a rear wall, a bottom opening and a top opening; a separator roller rotatably mounted below the media contact surface and having a first portion of its surface radially extending through a corresponding aperture in the media dam and a second portion of its surface radially extending through a corresponding aperture in the rear wall of the channel; and a roller nip formed in the channel within the media tray by the separator roller and an opposing backup roller for advancing media through the channel; and a pick mechanism extending from the housing for advancing a topmost media sheet from the stack of media sheets in a media process direction, wherein the separator roller is rotatable counter to the media process direction for separating an adjacent media sheet from the topmost media sheet if the adjacent media sheet is double fed with the topmost media sheet when the topmost media sheet is advanced by the pick mechanism.
