    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： Substrate (or marking material) pre-heating is employed to facilitate fusing of the marking material with the substrate and with adjacent marking material. By heating primarily the material which becomes the interface between substrate and marking material, and by minimizing the distance between the point of heat application to the substrate (or marking material) and the marking nip in a print system, the amount of time for heat energy to dissipate prior to the application of the marking material to the substrate surface is minimized, meaning that the total amount of energy required to drive the heat source can be reduced. Addressable heating may be employed to further reduce energy consumption. Furthermore, optical heating may be used to provide rapid, on-demand heating, thereby reducing warm-up time as well as reducing unutilized heat energy.

    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 system comprises an electro-wetting subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electro-wetting subsystem comprises a photo-responsive photoreceptor, a charging mechanism, an image definition material reservoir, a charge erase mechanism, and an exposure subsystem, such as a light source and rotating polygon forming a raster output scanner (ROS) disposed for exposure of the photoreceptor through the image definition material reservoir. The imaging member comprises a reimageable surface having certain properties, such as having a low surface energy to promote ink release onto a substrate. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor, which is developed with image definition material. The image definition material pattern is transferred to the reimageable surface. The pattern is developed with ink. The inked image may be transferred to a substrate.

    摘要： A system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed. This negative image is then transferred to the reimageable surface. The negative image is then developed with ink. The inked image may be transferred to a substrate.
