Patent ID: 8422931

Claim:
An apparatus comprising: a media transport configured to transport media; a media marking engine coupled to the media transport, the media marking engine configured to mark an image on media transported by the media transport to create unfused marked media; a fusing member coupled to the media transport, the fusing member being a first roller member having an axis of rotation, the fusing member configured to fuse the image on the media; a pressure member being a second roller member coupled to the fusing member at a fusing nip through which the unfused marked media passes for fusing, the pressure member having an axis of rotation parallel to the axis of rotation the fusing member; a prime mover coupled to the fusing member, the prime mover being configured to adjust a position of the fusing member and the pressure member with respect to an unfused marked media travel direction; a media motion sensor disposed downstream of the media marking engine and configured to sense travel information based on the unfused marked media travel direction, the unfused marked media travel direction deviating from a longitudinal axis of a portion of the media transport between the media marking engine and the fusing member, and configured to output a media motion sensor signal corresponding to the travel information; and a controller coupled to the media motion sensor, the controller being configured to output an alignment angle signal in response to receiving the media motion sensor signal, the alignment angle signal corresponding to an alignment angle between the fusing member axis of rotation and the unfused marked media travel direction, the controller being coupled to the prime mover and configured to control the prime mover using the alignment angle signal to adjust the alignment angle between the fusing member axis of rotation and the unfused marked media travel direction to maintain the alignment angle consistently at a right angle, and the fusing member including a first end and a second end, the apparatus further comprising a pivot point to which the first end of the fusing member is coupled, the prime mover being coupled to the second end of the fusing member.
