ABSTRACT:
After the digital copier has been assembled, a magnification error is calculated. The magnification error is a size ratio of a 100% copied image to an original image. The main CPU of the copier changes the rotational speed of the polygon-mirror driving motor to a new speed, in accordance with the magnification error. Further, the main CPU changes the speed of the main motor for the photosensitive drum in accordance with the new speed of the polygon-mirror driving motor. Therefore, the magnification of any copied image can be minutely adjusted by changing the rotational speed of the polygon-mirror and photosensitive dram.
