Abstract: The present invention is a control for automatically providing inserts into a copy set corresponding to inserts in the document set including an optical sensor responding to the reflectance of an original document that allows logic circuitry to determine if the original is white or non-white paper. If non-white, the logic of the control switches to a predetermined paper feed tray or paper bypass where the operator has placed an insert copy paper or cover stock, thus, the appropriate paper tray is selected to place inserts in the correct locations within the copy sheet.
