ABSTRACT:
An automatic scanner calibration method and apparatus is disclosed in which a calibration target, such as a Kodak® gray strip, is attached to a scanning surface of a scanner. During a normal scan, the calibration target area can be ignored or scanned depending on user selection. If the calibration target is scanned, then the resulting information is used to calibrate the scanner automatically. Such calibration is more accurate than an older in time or preset default calibration. Another embodiment of the invention actuates a print of a printer calibration target on a printer on a scheduled basis. Thereafter, the user can take the printer calibration target and place it on the scanner and perform a calibration of a scanner/printer system.
