CHAPTER 8 PAPER DECK PEDESTAL
IV. PAPER DECK UNIT
A. Basic Construction
The paper deck unit controls the operation of each load according to the signals from
the pedestal controller PCB to send paper to the copier.
Each of the loads used to pick-up and feed paper or raise the lifter is driven by the
pedestal motor.
If you operated the deck size switch, the size of the paper inside the deck is
communicated to the copier through the pedestal controller PCB.
