ABSTRACT:
A coin actuated print control device for operating a conventional electrostatic or bond copy machine, the device having a coin-operated mode and a direct print bypass mode. The device is easily and quickly coupled to a conventional electrostatic or bond copy machine, eliminating complex, electrical modifications of the conventional copy machine circuitry for providing for reliable coin actuated or bypass operation. The control device circuitry includes a power control relay which provides power to a receptacle plug in the device which is connected to the copy machine, a variable time delay circuit to allow warm-up time between coin actuation and print actuation, and a variable print process timing circuit to allow for power process print time (necessary for different copy machines) prior to shut down of the device.
