After the side fences have jogged and aligned the sides of the stack, the switchback roller lift motor (M7)
turns on and lowers the switchback roller [1] until it contacts the paper [2]. Next, the jog motor (front) (M4)
and jog motor (rear) (M5) reverse and retract the front and rear jog fences [3] to their home positions.
The stacking roller motor (M1) turns on and drives the switchback roller which feeds the paper at 700 mm/
s in the reverse (switchback) direction. At this time the TE press lever motor (M3) raises and opens the TE
press lever [4]. As soon as the sheet has fed in the switchback direction for the prescribed time, the motor
reverses, and then lowers and clamps the trailing edge of the sheet. The signal from the paper detection
sensors (front/rear) (S1/S2) lower the stacking tray. These sensors (mounted on the TE press lever) control
the operation of the stacking tray lift motor (M2).
After the TE press lever has clamped the trailing edges of the sheets in the stack, the switchback flapper
motor (M8) turns on and returns the switchback flapper to its home position to receive the next sheet. At
the same time the switchback roller lift motor (M7) turns on, raises the switchback roller, and returns it to
its home position to receive the next sheet. After the switchback roller has been raised, the stacking roller
motor (M1) resumes its rotation at the same speed of the host machine exit rollers.
The size of the paper selected for the job determines:
• Standby positions of the side fences
• Which sensor pair is used to detect the home positions of the fences
