Externally heated fuser device with extended nip width
摘要:
A fuser device for an electrostatographic reproduction apparatus. The fuser device includes an externally heated fuser roller having a thick elastomeric cover. An external heater assembly is positioned in operative association with the fuser roller. The external heater assembly has a low mass, fast-acting heating element to transfer heat rapidly to and from the external surface of the elastomeric cover of the fuser roller. A pressure film belt assembly is also in operative association with the fuser roller, spaced from the external heater assembly. The pressure film belt assembly has a pressure applicator which maximizes thermal contact and mechanical energy to define an optimum nip pressure profile providing an extended fusing nip with the fuser roller, thereby yielding quick starting, with superior energy efficiency and exceptional temperature control for the fuser device that provides proper image quality for photos, text, and graphics for high quality reproductions with consistent gloss (luster).
