ABSTRACT:
A method and apparatus to accurately control the size of the spots or dots produced by individual lasers within an array of lasers of an image scanning device is disclosed. The lasers are driven in accordance with image information indicating an image to be scanned onto the image bearing member. Output intensity feedback information from each of the lasers is obtained by monitoring an intensity output from each of the lasers. Using this feedback information, the driving energy values of the lasers are adjusted to overcome any unwanted nonuniformities or otherwise calibrated. The invention can also be implemented as an apparatus. Regardless of how the invention is implemented, an image scanning/forming apparatus utilizing the invention is able to scan or print with an array of lasers without being susceptible to streaks and other defects which otherwise occur during the printing or scanning of an image when all of the lasers do not function in a uniform and consistent manner.
