    摘要： A fuser for fixing toner, for example, toner images, includes thermoelectric control devices for controlling temperature. Preferably, the thermoelectric control devices are used to heat the toner in a heating zone and cool the toner in a cooling zone prior to separation of the toner from a fusing surface. The cooling improves both the gloss and the separation characteristics of the toner.

    摘要： A calibration station (34) for a printhead (20) adapted to provide a beam of electromagnetic radiation from a variable electromagnetic energy source onto a sensitive radiation medium, the calibration station (34), incorporates a sensor (26) disposed for sensing the beam (16) provided by the printhead (20), wherein the sensor (26) provides an output sensor signal indicative of the sensed power of the beam (16). A control circuit is adapted to accept the output sensor signal from the sensor and adjusts the variable electromagnetic energy source. A filter is disposed in the path of the beam (16) between the printhead (20) and sensor (26), adapted to transmit to the sensor (26) a portion of incident electromagnetic radiation over a predefined range of wavelengths, dependent upon a measured response characteristic of the radiation-sensitive medium.

    摘要： There is disclosed a thermal printer system having a multiple channel laser print head which focuses closely spaced spots of laser light energy onto a dye donor element which moves at constant velocity relatively past the print head. These laser light spots respectively print multiple lines of an image a swath at a time by heat transfer of pixels or subpixels of dye from the dye donor element to a receiver element. A light source (such as an arc lamp) applies to the dye donor element one or more precisely positioned spots of light energy which elevate the temperature of the dye donor element substantially uniformly within a zone coincidently with and closely surrounding the laser light spots. The shape, the position and the power absorbed within the zone from the light source are carefully controlled. Thus the temperature within this zone is held to a substantially uniform value slightly below the vaporization temperature of the dye to be transferred from the dye donor element. In this way the linearity and fidelity of a printed image are substantially improved, and "printing artifacts" such as banding and streaking are reduced.

    摘要： A method of scanning is disclosed in which an array of light sources is used to record an image on a light-sensitive recording medium. Each of the light sources is modulated in accordance with an information signal. Multiple passes of the array are made relative to the recording medium, and a set of raster lines is recorded in each pass. The raster lines of successive sets are interleaved to space the raster lines closer together than the spacing of the light sources in the array. In order to provide precise spacing of the raster lines, the array of light sources is advanced a constant distance between successive sets of raster lines.

    摘要： A method is disclosed for calibrating a reflectometer using black and white references observed in locations optically different from the sample location. Dark and light standards are selected to have reflectance values, while examined in the detection location of the test elements, that are within .+-.0.005 and .+-.0.05 of the values of the black and white references, respectively, when examined in a location displaced from the detection location of the test elements. Such standards are then read on a referee reflectometer having "ideal" black and white references, and the reflectances so read on the referee reflectometer are recorded for use as calibrating factors in making reflectance readings for the test elements.

    摘要： A digital film grain (20) comprises a phototransistor (40) which produces an electrical signal having a strength which is related to an input radiation flux. A transponder receives commands and power from a base station (80) and transmits information quantifying the radiation observed by that digital film grain. An image accumulator (84) connected to the base station (80) assembles an image from the profile of radiation reported by a distribution of digital film grains correlated to the locations of those grains.

    摘要： Exposure of a medium is controlled by changing an emission level of a radiation source from a first power to a second power. The second power emits for less time than required by an irradiance profile to traverse a full-width at half maximum of the irradiance profile projected onto the medium along a direction of relative motion between the irradiance profile and the medium. The emission level changes to the first power emits for less time than required by the irradiance profile to traverse the full-width at half maximum of the irradiance profile projected onto the medium along the direction of relative motion between the irradiance profile and the medium. Then the emission level changes to the second power. Brief pulsing of a single binary source can transfer intermediate amounts of thermally transferable colorant from a donor exhibiting a continuous-tone transfer response.
