ABSTRACT:
A timing system for controlling the timing sequence of a copy machine capable of accommodating variable copy length and having multi-copy, in-transit capability. The copy cycle control system includes two separate timers. A switch is actuated by the leading edge of an original to be copied and enables the first timer. The second timer is enabled by the same switch when it is turned off as a result of the trailing edge of the original passing thereover. This allows multiple copies to be made without the machine ceasing operations prematurely regardless of the size of gap between originals.
