F. Paper Deck Pedestal-K1
1. 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 inside of the deck is communicated to the copier
through the pedestal controller PCB.
