The operation sequence of the duplex unit is controlled by the duplex controller PCB. An 8-bit microcomputer mounted on the duplex controller PCB controls the
operation sequence of the duplex unit and the serial communication with the DC controller PCB.
The duplex controller PCB drives motors in response to various commands sent from the DC controller PCB. The DC controller PCB sends the duplex unit status
back to the printer. The duplex unit is powered by 24 VDC supplied from the power supply kit PCB and +5VDC and +3.3 VDC supplied from the DC controller
PCB.
The duplex unit circuit configuration is shown below.
