    摘要： A dual-zone steam fuser for a xerographic system includes a ultra-heated first zone maintained at 200-500° C. that quickly heats a paper substrate to an optimal toner fusing temperature (e.g., 120-150° C.), and a second, relatively cool second zone for maintaining the substrate at the optimal temperature during completion of the fusing process. A conveying system conveys the substrate so that it exits the first zone and enters the second zone immediately after the substrate temperature reaches the optimal toner fusing temperature, and is maintained in the second zone for a predetermined fusing operation time period. The gas (e.g., steam) temperatures and timing are selected such that surface condensation is minimized during initial heating, and such that moisture content is normalized at the end of the fusing process.

    摘要： A non-atmospheric pressure vapor oven system that utilizes a controllable pressure zone to facilitate fast phase change heat transfer at any desired temperature to heat or cool flat substrates, and to level temperatures across different locations of the substrates. The system enables the use of a heat transfer fluid, such as water, without being limited to a particular temperature, such as the fluid's natural boiling point at atmospheric pressure. The system includes a vapor oven (hermetic enclosure) defining a pressure chamber having sealed entry and exit ports for transferring an object (e.g., a sheet of paper) with added material (e.g., toner) through the pressure chamber, and a pressure regulation apparatus for setting the saturation temperature (boiling point) of heat transfer fluid inside the vapor oven to an optimal heating/cooling temperature by selectively controlling the pressure inside the hermetic enclosure.

    摘要： Methods and apparatus for performing addressable fusing and/or heating of a substrate undergoing xerographic processing are disclosed. The apparatus includes a fuser having an array of addressable heating elements in radiative communication with a substrate through a fuser roll or fuser belt. The array of addressable heating elements is operated to selectively heat portions of the substrate to achieve a desired effect on the substrate, such as changing its surface finish, or fusing unfused toner to the substrate. In the case of toner fusing, the array is operated such that substantially only an area covered by the unfused toner is heated. This eliminates the need for blanket fusing, and generally provides for greater flexibility in xerographically processing substrates. Apparatus and methods for performing two-sided selective fusing and/or heating are also disclosed.
