2.5 CORNER STAPLING
2.5.1 STACKING AND JOGGING
[A]: Jogger Fence Motor (M15)
[B]: Jogger Fences
[C]: Positioning Roller
[D]: Jogger Fence HP Sensor (S15)
[E]: Stapling Edge Pressure Plate Solenoid (SOL4)
[F]: Pressure Plate
At the beginning of the job, the jogger fence motor (M15) [A] switches on and moves the jogger
fences [B] to the standby position (7.5 mm from the sides of the selected paper size).
When each sheet passes the pre-stack tray exit sensor (S2) and enters the stapling tray:

The jogger fence motor switches on and moves the jogger fences to within 5.5 mm of the
sides of the selected paper size.

The positioning roller solenoid (SOL3) switches on for the time prescribed for the paper size.
This pushes the positioning roller [C] onto the sheet and pushes it down onto bottom fence.
This aligns the edge of the stack.
Next, the jogger fence motor:

Switches on again and moves the jogger fences to within 2.6 mm of the sides of the stack to
align the sides of the stack.

Reverses and moves the fences to the standby position (7.5 mm away for the sides) and
waits for the next sheet.
