Abstract: A method for adjusting a controller of a scanner includes obtaining a scan of a predefined image. The method further includes moving the sensor-element signals of the control signal pattern generated by the controller earlier in the pattern by at least one unit and obtaining an additional scan. The obtaining and moving are repeated until a comparison of a latest additional scan to the image is worse than a comparison of a second-latest additional scan to the image. Another method obtains a noise-reducing heuristic which modifies a time parameter of a sensor-element signal. A set of repeated scans of a same scan line is obtained, noise is measured there from, the time parameter is modified by one predetermined unit, and the process repeats until the noise measured from the latest set of repeated scans is worse than that from the second-latest set of repeated scans.

Abstract: A scanner includes a scan bar and a calibration strip. The scan bar has perpendicular fast-scan and slow-scan axes. The scan bar has an image sensor plane and includes a substantially linear array of sensor elements substantially aligned along the fast-scan axis. A first method for calibrating the scan bar includes imaging the calibration strip to the image sensor plane of the scan bar wherein the imaging is out of focus substantially-along the slow-scan axis. The first method also includes obtaining a calibration reading of the sensor elements from the imaging of the calibration strip. A second method includes imaging the calibration strip to the image sensor plane of the scan bar wherein the imaging is optically widened substantially-along the slow-scan axis. In a third method, the imaging is optically widened substantially-along the slow-scan axis using a cylindrical lens having an imaging-widening axis.

Abstract: A scanning system for generating an image includes a scanning device configured to receive light reflected from a document and to output a signal corresponding to the received light to collect image data for use in generating an image. An automatic document feed system is configured to move the document from a position upstream of the scanning device toward a position downstream of the scanning device along a document feed path in proximity to the scanning device to allow the scanning device to receive light reflected from the document. A processor includes logic that compensates for changes in document movement past the scanning device using document motion data to reduce motion error induced image defects.
