ABSTRACT:
A paper web recording medium provided with toner images as conducted through a fixing housing containing solvent vapor over a paper deflection drum for fixing the toner images on the recording medium. The paper deflection drum is formed by a rigid roller body made of expanded or foamed plastic over which an elastic grid network fabric of toner-repellent material is drawn as an exterior surface sleeve. A low-mass paper deflection roller having low thermal conductivity is thus provided, so that no solvent vapor can condense at the surface of the fixing drum. The low-mass structure of the paper deflection drum also prevents a smear print when starting or stopping conduct of the paper web through the fixing housing.
