5. TURN GATE
The turn gate [A] sends copies to the proof tray or the sorter bins depending
on the mode. In the proof mode, the turn gate solenoid [B] turns on and the
main motor [C] turns clockwise when the
key is pressed.
The turn gate [A], directs copies upward through the proof transport section
to the proof tray. In this mode, main motor drive is transmitted by both the
proof drive belt [D] and sorter drive belt [E]. However, the one-way clutch in
each sorter transport roller drive gear [F] does not transmit the drive to the
sorter transport rollers.
In the sort, stack, and staple modes, the turn gate solenoid stays off to direct
copies downward to the sorter transport section. When the
key is
pressed, the main motor [C] turns counterclockwise.
In this mode, main motor drive is not transmitted to the proof drive belt [D]
because of the one-way clutch in the pulley [G]. The entrance [H] and the
proof exit [I] sensors check for paper jams.
