ABSTRACT:
Minimum elapsed time between successive multiple copy nonoverlapped runs is achieved detecting the last copy as it exits from a paper path in any one of a plurality of exit locations. Means establish a last-copy watch for partially enabling the last-copy detector. Means indicate that the paper path leading to the exit is substantially clear of any copies and, finally, the trailing edge of the exiting document at a given one of said exit positions triggers the last-copy detector to signify that a new copy run condition is "go".
