ABSTRACT:
An apparatus which generates timing pulses in an electrophotographic printing machine. A flexible member having spaced, marks formed photographically thereon is mounted on the shaft of the photoconductive member to rotate in unison therewith. As the flexible member rotates, the spaced marks are detected to generate a timing pulse output in response thereto. The detector prevents the member from deflecting to control the axial motion of the flexible member during the rotation thereof.
