Page 927 Junction Gate Mechanism 2.5 JUNCTION GATE MECHANISM The junction gate [A] directs any paper reaching the bridge unit to either the upper tray (on top of the bridge unit) or to the finisher, depending on which has been selected. If the junction gate solenoid has been activated, the junction gate [A] points downward and directs the paper to the upper tray [B] (dotted line path in illustration).

Page 986 Paper Feed 2.2 PAPER FEED 2.2.1 PAPER FEED MECHANISM This machine uses the FRR paper feed system (paper feed roller [E], separation roller [H], pick-up roller [G]). When the right door is closed, the tray lift motor raises the tray to the position where the top of the paper stack in the tray interrupts the tray lift sensor [D].
Page 987 Paper Feed 2.2.2 TRAY LIFT MECHANISM The lift motor [A] controls the vertical position of the tray through the timing belts [B]. Tray lifting conditions When the tray lift sensor [C] turns off in the following conditions, the tray lift motor raises the tray bottom plate until the tray lift sensor [C] turns on again.
Page 988 Paper Feed 2.2.3 PAPER HEIGHT AND END DETECTION Paper Height The amount of the paper in the tray is detected by combination of high (1)/low (0) outputs from three sensors (paper height sensor 1 [A], 2 [B], 3 [D] and sub paper height sensor [C]). Indicator on the Amount of paper PH S-1...
