ABSTRACT:
A programmable controller is used to control the operation of a xerographic reproducing machine adapted to run in a simplex or duplex mode whereby copies are made on either or both sides of web material fed in a single pass and then cut into individual copy sheets. A control program, comprised of a set of program instructions, enables the controller to generate control signals for actuation of the process devices of the reproducing machine in a timed manner for production of copies as directed by the operator. In response to instructions by the operator concerning copy length, copy numbers, etc., the control program permits the calculation of requisite timing information for control of the machine operating components. The control program permits the operation of the reproducing machine to concerning copy length, copy numbers, etc., the control program permits the calculation of requisite timing information for control of the machine operating components. The control program permits the operation of the reproducing machine to be responsive to the machine status in control of the machine operating components.
