ABSTRACT:
A printer is provided including a reference edge, a fuser assembly, a cooling apparatus and a controller. The reference edge is adapted to be contacted by a substrate as the substrate moves along a substrate path through the printer. The fuser assembly includes a heat transfer member including a belt and a backup member. The cooling apparatus is adapted to move cooling air capable of cooling the fuser assembly. The controller is configured to activate the cooling apparatus after determining that a first end portion of the backup member opposite a second end portion of the backup member near the reference edge is at a temperature above a predefined first threshold temperature.
