Ordinarily, the side bar [A] is in the home position. It moves to within 10 mm
of the rear of the selected paper size. The side bar is driven by the side bar
motor [B] through the gears and a timing belt.
The jogger arm [C] home position is 10 mm in front of the paper.
After the paper passes the jam sensor, the jogger arm moves twice due to
the forward and reverse rotation of the jogger motor [D]. Jogger arm
movement is controlled through the link [E] and jogger bar [F].
The reverse rotation of the jogger motor prevents motor lock caused by an
overly stiff paper stack. Even if the overly stiff paper interferes with the jogger
arm movement, the arm returns to its home position via the reverse rotation
of the jogger motor.
