Abstract: A method and apparatus for detecting roller eccentricity in a CIS scanner is disclosed. An image of a target is captured using the CIS scanner. The image of the target is analyzed for periodic horizontal banding. The period of the periodic horizontal banding is compared with the circumference of a pressure roller in the CIS scanner. When the period matches with the circumference of the pressure roller, an error is set.
