Abstract

Apparatus for heat fixing toner images electrostatically adhered to copy papers The apparatus is characterized by the provision of a radiant energy source 12 together with a reflector 14 for focusing the radiant energy on toner images 17 to thereby soften the images~ A fusing window 26 is interposed between the radiant source and the copy paper or support material 18 having the toner images thereon~ The window prevents the copy paper from contacting the heat source and the reflector~ The window comprises an elongated web of radiant energy transrnissive material a portion or segment of which is disposed in the path of the radiant energy until such time as it becomes overly contaminated from toner offset thereto, or dust, whereupon the contaminated segment is replaced by an uncontaminated segment of the webs
