Abstract

A cop ing/printing machine which inherently dispenses the copy sheets first age P irst and last page last, causes the copy sheets to stack in the output tray [rst page on the bottom with last page on the top. Because the machine may be used to create originals, it is sometimes desirable to have an output tray that will provide collated copies with last page on the bottom and first page on the top.
