Abstract

This is a pre-heater system especially useful in an electrostatic marking apparatus. It is used to heat the toner and paper (media) prior to the paper entering the conventional fuser station. Using this pre-heater increases fusing productivity (ppm), widens media latitude and/or extends fuser member life for a given fuser system. It also dramatically improves uniform heat transfer and paper handling problems encountered in prior art preheat fusing assemblies. The preheater is used together with the conventional fuser stations used today in electrostatic marking systems.
