Abstract
Backlit messages guide the operator through the process of making duplex copies in either a simplex to duplex or duplex to duplex mode. The queing or sequence of the messages will adapt to the order of operator activity or performance to instruct the operator on the next operation to be performed. Once certain operations are performed, some backlit messages are turned off. In particular the messages instruct the operator to determine if specific paper trays are empty, to suitably load a recirculating document handler, to remove copies from one tray and place in a second tray, and to reposition documents in the document handler.
