Abstract

Figs. 1 and 2 show a fixing apparatus for fusing toner onto a support sheet. The fixing apparatus includes a reflector formed from two non-linear reflective members. The members are joined along its longitudinal axis, and an illumination source is positioned within the reflectors.

Flash Fuser Reflector

Figs. 1 and 2 show a fixing apparatus for fusing toner onto a support sheet. The fixing apparatus includes a reflector formed from two non-linear reflective members. The members are joined along its longitudinal axis, and an illumination source is positioned within the reflectors.

In Fig. 1 the reflector is formed from two ellipses. The ellipses are configured in an overlapping manner and joined so that two foci of each elliptical section coincide. A flash lamp is placed at the center of the foci. A cooling tube is positioned around the flash tube.

Fig. 2 shows an alternate configuration for a fixing apparatus.

In this configuration, two circular arcs are joined to form the reflector. If the flash lamp is placed .5R to the side and .3R up from the center, the circular arc will behave like an ellipse and focus most of the rays to spots on either side of the lamp. If the paper plane is placed 3.8R on the center, the most even illumination will occur on the paper plane.
