  • Patent number: 10216141
    Abstract: An imaging device having a fuser and print engine architecture that enables complete interchangeability between fuser types with a common print engine. The imaging device has a frame configured to separately receive a first fuser assembly of a first fuser type and a second fuser assembly of a second fuser type different from the first fuser type. The first fuser assembly includes a first fuser frame having a first datum tab. The second fuser assembly includes a second fuser frame having a second datum tab. The frame of the imaging device has a datum aperture that is sized to receive the first datum tab that when inserted into the datum aperture, causes the first fuser assembly to be positioned at a first operative position, and the second datum tab that when inserted into the datum aperture, causes the second fuser assembly to be positioned at a second operative position.

  • Patent number: 10185285
    Abstract: A common media redrive system for use with either a hot roll fuser assembly and a belt roll fuser assembly installed an imaging device. The redrive systems includes an access door movable between a raised closed and a lowered open position. The access door has a media path channel and a deflector mounted over the channel. The deflector has a pivotable gate and includes upper and lower media guide members forming a media entrance and two exits for directing a media sheet from the fuser assembly exits to an output area and duplex path portion, respectively, via the gate and the first and second exits, respectively. A pair of media exit guide portions cantilever from the rear portion of the fuser assembly. The lower media guide members includes a pair of cutouts that receive the pair of media exit guide portions when the access door is in the closed position.
