B. Paper exit arm control
(1) Stapling mode (when the paper length is shorter than B5S in the paper feed
direction)
• Completing the stapling operation, the paper exit roller motor rotates to drive the paper
exit belt in the stacker section. The paper exit arm lifts up the paper to the paper exit
roller, and then the paper exit roller exits the paper to the finishing tray1.
• The paper exit roller motor stops when the paper exit belt home sensor turns ON.
(2) Stapling mode (when the paper length is B5S or longer in the paper feed direc-
tion)
• Completing the stapling operation, the paper exit motor rotates. When the paper exit
home sensor detects the paper exit opening is closed, the paper exit roller motor rotates
to drive the paper exit arm in the stacker section. The paper exit arm lifts up the paper to
the paper exit roller, and then the paper exit roller exits the paper to the finishing tray1.
• The paper exit roller motor stops when the paper exit belt home sensor turns ON.
(3) Folding/saddle stitching mode
• After completing the stapling operation, the saddle stitching stopper motor drives the
saddle stitching stopper to move the paper to the folding position. To prevent the paper
exit arm to contact with the paper standing by at the folding position, the paper exit arm
does not rotate.
(4) Tri-folding mode
• The paper exit roller motor rotates in the reverse direction to assist in transferring the
paper to the tri-folding position after completing the paper alignment operation.
• The paper exit roller motor stops when the paper exit belt home sensor turns ON.
