Description of Interface Signals

The 2 lines; TxD and RxD are used to transmit/receive signals between the equipment and the Finisher.
When the Finisher is connected, the equipment detects the power supply signal (MFP-24V-ON) and
confirms that the Finisher is connected to it with the status of the connection switch (SW4) and an MFP-
CONNECT-SEN signal from the connection sensor (S25).

Data communication (RxD and TxD) between the equipment and the Finisher has adopted the serial
communication system which does not allow checking whether the signals are transmitted/ received
properly using testing devices in the field.
