Abstract
A system for calibrating a scan module of an automatic document feed (ADF) scanner. The system includes a rotatable frame disposed on a position opposite to an imaging surface of the ADF scanner. An image backer and a calibration surface portion formed along longitudinal portions of the frame extend substantially parallel to the imaging surface. The image backer and calibration surface portion have top surfaces of different reflectivity that respectively does not contact and contacts the imaging surface when the frame is rotated to position the image backer and the calibration surface portion in a field of view of the scan module. A drive mechanism coupled to the frame is controlled by a controller to rotate the frame and selectively position within the field of view of the image capture module the image backer during a scanning operation and the calibration surface portion during a calibration operation.
