摘要: A method to compensate for imperfect scanner motion in a scanning apparatus having a moveable scanner includes generating an error array by measuring errors in a scanner position at each of a plurality of spaced positions along a direction of travel of the scanner; generating an error compensation array from the error array based on a low frequency component of the error array; and using the error compensation array to adjust at least one parameter associated with the scanning apparatus during a document scanning operation.
