Paper Abstract

Vibrations in a photocopier reduce the resolution of the image on the copy. Typically the image is transmitted via a system of four or six mirrors and a transmission lens to the photoreceptor. In a scanning copier two or three of these mirrors scan the document at a speed which synchronises the motion of the image with that of the photoreceptor. Vibrations of the mirrors, lens or photoreceptor cause the image of a point to move with respect to the photoreceptor during the exposure time, generating a two dimensional spread function. These vibrations can be controlled by both active and passive means. This paper outlines methods of image analysis used to identify the sources of the image disturbance, and means used to minimise their effects.
