Abstract

Because of manufacturing cost and time to heat up high mass fusers, there is a desire in some electrostatographic machines to use a low thermal mass radiant fuser such as that illustrated in Figure 1 with a fusing platen 10 in the base house 12 over which the copy sheet with the toner image to be fused is transported. The top comprises a fuser lamp 14 within a reflector cavity 16. The whole assembly may be made of sheet aluminum and air may be directed by a blower (not shown) through the assembly as indicated by the arrows to the assembly. Sufficient air should be provided to limit the base plate temperature when running a large number of copies at a slow rate. However, during warm up to the fusing temperature, the amount of air should be restricted since it tends to retard initial warm up of the base plate.
