Abstract:
1. A printer comprising: a reference edge adapted to be contacted by a substrate as the substrate moves along a substrate path through the printer; a fuser assembly comprising a heat transfer member including a belt and a backup member; cooling apparatus adapted to move cooling air capable of cooling said fuser assembly; and a controller coupled to said cooling apparatus to activate and deactivate said cooling apparatus, said controller activating said cooling apparatus after determining that a first end portion of said backup member opposite a second end portion of said backup member near said reference edge is at a temperature above a predefined first threshold temperature; wherein said cooling apparatus comprises a fan apparatus coupled to said controller, and said controller reaches a determination that said first end portion of said backup member is at a temperature above the predefined first threshold temperature after a predetermined first number of narrow substrates have been successively printed and, in response, activates said fan apparatus at a first speed.
