Abstract

A reproduction machine for making two-sided or duplex copies. When there is an odd number of simplex original documents to be copied in the duplex mode, the last copy sheet bears an image only on one side. The present invention provides a control system for operating various machine components in response to such an occurrence in order to optimize the throughput capability of the machine.
