Single-pass fusing of multi-layer duplex copies

摘要

A fusing station of an electrographic apparatus fixes in a single pass a duplex resinous powder color image to a support material as the support material is moved over a predetermined path through the fusing station. The fusing station employs a symmetrical fixing operation on both sides of the support material. The fusing station applies hot air to both sides of the support material in substantially equal flows. The hot air is heated by heating sources with substantially identical operational characteristics such that the flows of hot air are heated to substantially equal temperatures on both sides of the support material.
