Abstract: Signals from a color (multi-row) full width array sensor are used to detect and correct for motion quality issues in a constant velocity transport or platen document scanner. This capitalizes on the geometry of the full width array sensor, in which three or four rows of photo sites are arranged in the slow scan direction. For example, the arrival time of an image edge of the red sensor row may be compared to the slightly later arrival time at the blue sensor row, and the difference yields the velocity. The velocity can then be fed back to control the transport.

Abstract: A method and apparatus adjusting the lateral position of an LED bar may minimize image banding in image-on-image systems having multiple LED bar imagers. A photoreceptor may be transported past a plurality of marking stations. At each marking station an LED bar imager extends in a direction perpendicular to the direction of transport of the medium. A mark may be sensed at each station and the lateral position of the LED bar, perpendicular to the direction of transport of the medium, may be adjusted according to the deviation of the position of the mark from a desired position.

Abstract: A system and method of estimating the thickness of the individual sheets in a stack of sheets in a print media sheet input stacking tray before printing with an electronic sensing system for electronically detecting individual sheet edges in the stack thereof and a movement system providing a known traversal distance of the sheet edge sensing system relative to one side of the stack to produce multiple signals corresponding to multiple detected individual sheet edges, and dividing that multiplicity of signals into the known traversal movement to estimate the thickness of the individual print media sheets in the stack and provide a corresponding electrical output can be used for automatic control of sheet feeder, printer or finisher functions. A relatively simple contacting or non-contacting sensor may be used.
