Abstract
An electrostatographic printer includes an imaging station for forming a latent electrostatic image on the surface of a drum, a toner development station for developing the latent image to form a toner image, and a toner transfer station for transferring the toner image onto a moving web. An image-fixing station for fixing the toner image on the web includes two pairs of radiant heat sources, the peak energy output wavelength of which lies in the non-visible part of the spectrum. The radiant sources may be located in hingedly mounted pairs of housings in such a manner that the housings may be moved into a closed position to shield the radiant sources from the web when the speed of movement of the web falls below a predetermined value. Thus, damage to the web when movement of the web stops is avoided.
