ABSTRACT:
A method of controllably driving optics of a copier in the form of a scanner which is movable relative to an original document being laid on a glass platen. The optics is usually returned in a high-speed return mode after imagewise exposure so as to enhance rapid copying. In a two-sided or a composite copy mode in which a paper sheet is driven into an image forming station of the copier before the optics reaches a timing for starting forming an image, the high speed return mode for controlling the optics is switched over to a low-speed return mode.
