Abstract:
1. Apparatus for imaging a recording medium, the apparatus comprising: a. means for supporting the recording medium; b. an array of imaging devices positioned adjacent to the supporting means; c. a mechanism for rotating the supporting means about an axis; d. an axial-translation mechanism for drawing the array along the supporting means; and e. a controller for causing the imaging devices to apply on the recording medium, at a fixed dot pitch defining a distance between adjacent beams on the recording medium, a pattern of dots corresponding to an image, the controller operating the imaging devices and the axial-translation mechanism so that each device applies dots along a helical path interlacing with the helical paths of the other devices of the array, the pattern of dots corresponding to one of a plurality of selectable image resolutions notwithstanding the fixed dot pitch.
