2.2 JUNCTION GATE MECHANISM
Depending on the selected mode, the copies are directed to the output tray/ bridge unit
path or 1-bin tray/duplex path by the exit junction gate [A]. These are controlled by the
junction gate solenoid [B].
To the Exit Tray or Bridge Unit
The exit junction gate solenoid stays off and the paper is directed to the copier exit unit.
To the 1-bin Tray
The junction gate solenoid turns on. The paper is directed to the 1-bin tray.
To the Duplex Unit
The junction gate solenoid turns on. When the junction gate jam sensor [C} detects a
trailing edge of a sheet of paper, the machine stops the paper exit/inverter roller [D]
and then drives its roller reversely. As a result, a sheet of paper is transported to the
duplex path.
