ABSTRACT:
An apparatus for fusing toner images to a receiving sheet includes a belt, web or sheet having a hard surface against which the toner image is pressed while at an elevated temperature. The receiving sheet is separated from the hard surface only after the toner image has cooled. A cooling device for cooling the toner image includes an air supply plenum into which cooling air is forced. Walls defining the plenum include a nozzle wall that is parallel to and spaced from a surface of the receiving sheet or belt, web or sheet. A large number of nozzles extend toward the surface being cooled from the nozzle wall for directing air generally perpendicular to the surface being cooled. Air then exhausts from the space between the nozzle wall and the surface being cooled on opposite sides of the path of the receiving sheet.
