4060-xxx Duplex Option The duplex option interface is a six pin autoconnector that provides a +24 V dc, +24 V dc return, serial interface transmit signal, serial interface receive signal, and two ground pins. The duplex option receives the +24 V dc from the base printer for the duplex motors and also converts the voltage to +5 V dc for duplex electronics. Duplex chassis grounding is provided from the printer to the duplex option through a ground spring attached to the frame and base of the printer. The ground connection is automatically made when the option is installed below the printer. The paper input sensor is located in the rear of the duplex option under the input paper guide. The paper exit sensor is located on the left frame assembly. Option microcode The options are "Smart Options" or options that have a system board. The option system board has a microprocessor that controls the option mechanism. A software architecture is provided that controls the option and communicates information such as paper path status, sensor status, motor status, and so on to the base printer.
