Autoconnect cabling and connectors

The printer options make electrical connection automatically, requiring no external cables when the option is
mechanically installed under the printer. Communication between the option and the base printer stops when
you remove an option. The printer no longer recognizes the option and deletes associated messages. Each
installed option below the base printer provides an electrical autoconnect to the option attached below it. We do
not recommend to attach or "Hot Plug" any options with the base printer power turned on.

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.
