    摘要： A compact structure and rapid method for calibrating a document scanner provides for a substantially cylindrical calibration casing having a central axis and an outer surface, with a brightness calibration section of the outer surface encompassing a portion of the circumference of the outer surface, a document width detection segment encompassing a second portion of the circumference of the outer surface, and a document backer element encompassing a third segment of the circumference of the outer surface of the casing. A driver selectively positions the casing in different rotational positions in which the different segments of the outer surface of the cylinder face the optical element of the scanner.
