A fuser assembly configured to fix a toner image to a sheet of print media includes a fuser belt having a first side edge, a second side edge spaced apart from the first side edge, an exterior surface, an interior surface, and a hollow interior defined by the interior surface. A pair of end cap assemblies is positioned to locate the fuser belt, and the fuser belt is positioned between and supported by the pair of end cap assemblies. Each end cap assembly of the pair of end cap assemblies includes an end cap body and a belt support mechanism. The belt support mechanism is coupled to the end cap body for supporting the fuser belt and is configured to be compliant in a direction perpendicular to a rotational axis of the fuser belt to apply a biasing force to the interior surface of the fuser belt.
