Abstract: A fuser for fusing toner images to a receiving sheet includes a pressure roller and a fusing belt. The fusing belt has leading and trailing ends. A towing device is positioned to receive both the leading and trailing ends of the belt to form an endless belt. The towing device is moved through a path which moves the fusing belt through an endless path, which path includes a fusing nip with the pressure roller. The belt is backed by a heated roller at the fusing nip which defines a portion of the endless path and cooperates with the pressure roller to provide pressure in the nip.

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.

Abstract: A toner image is fixed to a receiving sheet by positioning the image between the receiving sheet and a hard surface of a web or sheet. Pressure is applied between the surfaces to fix the toner image to the receiving sheet with the toner image above its glass transition temperature. While the surfaces are still in contact, a heat sink member is brought into contact with one of the sheets or web to remove heat from the toner image and reduce the temperature of the toner image below its glass transition temperature allowing the receiving sheet to be separated from the hard surface without offset.

Abstract: A toner image, particularly a multicolor toner image is fixed to a receiving sheet, which may or may not have a heat-softenable outer layer, by use of a fusing sheet. The fusing sheet is preferably a hard, smooth sheet, for example, a metallic sheet. The fusing sheet is fed from a fusing sheet supply into overlying contact with the toner image on the receiving sheet. The fusing sheet and receiving sheet form a sandwich which is fed between a pair of rollers which apply heat and pressure to the sandwich to fix the toner image to the receiving sheet. The receiving sheet and fusing sheet sandwich is allowed to cool and is then separated. The fusing sheet is fed back to the fusing sheet supply.

Abstract: A toner image, for example, a multicolor toner image, is transferred to a receiving sheet carried by a heated transfer drum. The multicolor image is fixed by pressure between a fusing web or sheet and the toner image exerted by a heated pressure roller and the transfer drum. The fusing web or sheet and the receiving sheet are transported away from the transfer drum and pressure roller to cool, after which they are separated.

Abstract: A modular target system support structure for use with modular target systems simultaneously provides support and electrical contact to a plurality of target modules upon mounting and securing of the same in place on the support structure. In one embodiment, the modular target system support structure includes mechanical clamps for securing the plurality of target modules in place and electrical contacts, positioned on the mechanical clamps, for making electrical contact with the target modules automatically upon mounting and securing of the same in place. Furthermore, the modular target system support structure requires no tools for mounting or replacing target modules on or off the target field.
