Fuser overheat control

摘要

A printer for fusing images on sheets of at least three width size categories including small, medium, and large is operated by control through a microprocessor assigning -7 to full size sheets, +13 to small size sheets and +17 to envelopes. These are accumulated until the count reaches 127, at which the interpage gap is adjusted based on which of those three categories is being printed and which of the three categories will next be printed. This maximizes throughput without requiring a thicker fuser.
