  • Fuser with end caps having protuberances for reducing belt skew
    Patent number: 8204420
    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.
