An electrostatic copying machine of the type disclosed in Van Auken et al. application Ser. No. 30,923, filed on Apr. 22, 1970 now U.S. Pat. No. 3,677,635 and entitled "Copying Machine System". The Van Auken et al. machine includes a clutch and cam arrangement for controlling the early feed of copy paper while the original is being reverse transported in the multiple copy mode, and allows multiple copies of an original to be made very rapidly. The shortcomings of the clutch and cam arrangement are eliminated in the present invention by the substitution of an electronic circuit. A further advantage of the electronic circuit is that it permits a relatively simple adjustment to be made for achieving perfect registration between the original and each copy sheet.
