摘要： A multicolor-printer has at least a first and a second print station, first and second optical sensors and a surface recordings comparator. The first and second print stations are arranged to print images on a surface of a moving recording medium. The first and second optical sensors view, at the first and second print stations, an area of the recording medium surface to obtain at least one first surface recording, in a manner related to the first print station's image printing, and second surface recordings, respectively. A storage is arranged to store the first surface recording. The surface recordings comparator is arranged to test, during the recording medium movement, for correspondence of second surface recordings with the stored first surface recording. The printer is arranged to repeatedly, within one image, register raster lines of the image of the second print station to corresponding raster lines of the image of the first print station in response to correspondences found between the first and second surface recordings.

摘要： To assemble a printer chassis comprising three structural aluminium beams extending between two structural sideplates, the printer carriage beam is first attached to the sideplates by means of attachment points arranged along a straight line and then the printing beam and lower beam are attached to provide a vibration- and deformation-resistant chassis relative to which all the other printer components are referenced. Slider rods are mounted on the printer carriage beam by means of screws which hold the rods against the beam to keep them straight. The screws also pass through apertures in rod supports, the apertures being sized to permit longitudinal thermal movements of the rods relative to the beam.

摘要： A hardcopy apparatus includes a media holddown unit, having a platen, and a vacuum source for generating negative pressure on a medium positioned on said platen to keep it flat on said platen. The unit includes at least two vacuum chambers, both in air communication with the vacuum source. Each of the vacuum chambers can apply a negative pressure to a different portion of the medium positioned on a corresponding different region of the platen. A method for holding down a medium when placed on said platen. First the vacuum source is placed into independent air communication with a number of distinct regions of the platen, then the medium is positioned to cover one or more regions of the platen, and finally a negative pressure is applied to the back of the medium via the independent air communication.
