Shift gate/shifter drive mechanism

• If the Main Tray runs out of paper, while the Sub Tray is loaded with paper, the paper
stack on the Sub Tray is moved to the Main Tray.
• At this time, the Shift Gate Motor is energized to retract the front and rear Shift Gates.
• Then, the Shift Motor is energized to move the Shifter so that the paper stack on the Sub
Tray is moved onto the Main Tray.
• The Shifter continues moving and stops when the Shifter Return Position Sensor is acti-
vated. When the Drawer Release button is thereafter pressed, the Shifter starts moving
and stops as soon as the Shifter Home Position Sensor is activated.
