A xerographic reproducing machine including a manually operable start switch, a circuit responsive to actuation of the start switch for cycling from a standby condition to an operating condition for performing a process for copying a document, the copying process including machine preparation to a copy ready state and subsequent initiation of the sequential copying steps, a timing circuit for initiating the copying steps after achieving the copy ready state, and a standby circuit for cycling the machine to the standby condition after a predetermined time absent re-actuation of the start switch, the improvement comprising a delay control circuit connected to said timing circuit for delaying initiation of the copying steps after achieving the copy ready state, a switch for selectively activating the delay control switch, and a circuit responsive to activation of the delay control switch for bypassing the standby circuit. |

DETAILED DESCRIPTION The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
In a xerographic reproducing machine including a manually operable start switch, means responsive to actuation of the start switch for cycling from a standby condition to an operating condition for performing a process for copying a document, the copying process including machine preparation to a copy ready state and subsequent initiation of the sequential copying steps, a timing circuit for controlling initiation of the copying steps to permit achieving the copy ready state, and a standby circuit for cycling the machine to the standby condition after a predetermined time absent re-actuation of the start switch, the improvement comprises means connected to the timing circuit for delaying initiation of the copying steps after achieving the copy ready state, means for selectively activating and deactivating the delaying means, and means responsive to activation of the delaying means for bypassing the standby circuit.
The delaying means preferably comprises a timer which, when activated, interposes a delay between achieving the copy ready state and initiation of the copying steps, the timer interposing either a predetermined delay or being selectively variable.
In an alternative embodiment, the delaying means requires a command before initiating the copying steps and includes means for providing that command, such as a foot pedal.
Preferably, the machine includes means responsive to actuation of said delaying means for automatically generating two sequential processes for copying a document upon actuation of the start switch, the delaying means controlling initiation of the copying steps of the second sequential process.
