Patent ID: 7817315

Claim:
A method for adjusting a controller of a scanner, wherein the scanner includes a scan bar having sensor elements, a cabling system operatively interconnecting the controller and the scan bar, and a predefined image and wherein the controller is adapted to generate a pattern of control signals including sensor-element signals without considering the amount of time the control signals will take to be sent over the cabling system and to send the control signals over the cabling system, wherein the control signals of the pattern are updated for each unit of a predetermined update time, comprising: obtaining a scan of the predefined image; moving the sensor-element signals earlier in the pattern by at least one unit; obtaining an additional scan of the predefined image with the sensor-element signals moved earlier in the pattern by the at least one unit; and repeating the moving and the obtaining of an additional scan until a comparison of a latest additional scan of the predefined image to the predefined image is worse than a comparison of a second-latest additional scan of the predefined image to the predefined image; and modifying the controller to acquire future scans of images with the sensor-element signals moved earlier in the pattern by the number of units corresponding to the second-latest additional scan of the predefined image.
