BASIC OPERATION

2.1 BASIC OPERATION
[B]
Proof Tray
When the proof tray is selected as the output tray and the exit sensor of the main
machine is actuated by the leading edge of the paper, the transport motor and
proof tray transport motor energize, causing the transport rollers to turn.
Soon after the motors start, the proof tray junction gate solenoid energizes and the
proof tray junction gate [A] is lowered so that the paper goes to the proof tray.
When the last page passes the proof tray exit sensor and feeds out, the proof tray
junction gate solenoid and the proof tray transport motor de-energize.
Bridge Unit
The relay junction gate [B] in the bridge unit delivers the paper either to the finisher
or down to the trays. When the finisher is selected as the output tray, the relay
junction gate stays closed, and the paper goes to the bridge unit. When a tray is
selected as the output tray, the relay junction gate solenoid energizes and the relay
junction gate is open so that the paper goes downwards to the tray area.
Trays
When the proof tray is selected as the output tray, the transport motor and the
vertical transport motor energize. Each tray gate [C] is individually controlled by a
solenoid. When a solenoid is energized, the tray gate opens and the paper goes
into the tray.
