Pickup/Feed Control
The paper deposited in the compartment is lifted by the lifter and stops at a specific level. When the start key on the host machine
is pressed, the drive of the deck pickup motor (M1) starts to rotate the pickup roller to pick up paper. At this time, the deck feed
roller and the deck separation roller operate to feed a single sheet of paper. When the deck pull-out sensor (PS2) detects the
deck pickup release solenoid (SL1) turns ON and the deck pickup roller away from the paper. The deck pull-out roller starts to
rotate when the deck pull-out motor (M2) is turned ON. The picked up paper is fed to the host machine.
