ABSTRACT:
A print media delivery system on a door assembly that is connected to an associated frame is provided. The door assembly includes a door body openable to provide access into an associated frame. A tray is pivotally connected to the door body for receiving associated print media thereon. A pick roller is rotatably mounted to the door body for contacting the associated print media and advancing the associated print media into the associated frame. A gear has a missing teeth section and is connected to the pick roller for corotation therewith. A gear bias system urges the gear to rotate in a first direction when the door body is closed and said tray is open to selectively advance the missing teeth section past an associated drive gear and allow teeth of the gear to engage the associated drive gear when the door body is closed.
