Controlling the Deck Pickup Motor (PM101)

The deck pickup motor is a stepping motor controlled by the copier's DC-CPU. The deck
pickup motor is turned on and off by controlling the output of the pulse signals from the copier
(DPUMA, DPUMA*, DPUMB, DPUMB*); on the other hand, the deck pickup motor is kept on
hold by causing the deck pickup motor hold signal to go '1'.
