The deck main PCB (PDMPCB) consists of the CPU IC8, which serially communicates with the copier main PCB (MPCB);
the deck paper conveying motor drive circuit; the paper deck motor drive circuits; the clutch drive circuit; the reset circuit; and
the LED drive circuit. It controls the entire large paper deck.
