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.

Abstract: A fuser has a heater housing extending through an endless belt with end caps on the housing adjacent to opposite lateral sides of the belt. The end caps have inner flanges spaced radially outward from a center portion and radially inward from the opposite marginal side edge portions of the belt so as to define clearance therebetween. Protuberances on the inner flanges of the end caps project toward opposite marginal edge portions of the belt and are circumferentially spaced apart to reduce belt skew relative to the end caps by either decreasing the surface area of contact of the inner flanges with the opposite marginal side edge portions of the belt to reduced surface areas of contact of protuberances therewith or decreasing the radial height of the clearance between the inner flanges and opposite side edge portions of the belt to the reduced radial height between the latter and the protuberances.
