10. Stapler (FS-608)
C. Stapler movement control
(1) Size movement in 1 staple/front and 2 staples
• Transmitting the FNS signal from the main body, the stapler movement motor turns ON to
widen the distance between stapler and clincher. It stops when they are positioned at the
specified positions.
• The stapler movement motor turns ON after a specified period of time since the finishing
tray1 paper exit sensor detects the last paper. The stapler movement motor stops when
the stapler movement home sensor turns ON.
(2) Size movement in 1 staple/one-corner stapling at rear
• Transmitting the FNS signal from the main body [1], the stapler movement motor turns
ON to widen the distance between the stapler and the clincher [2].
• The stapler rotation motor and the clincher rotation motor turn ON to rotate the stapler /
Rr and the clincher /Rr and move them diagonally [3] after a specified period of time
since the stapler movement motor turns ON.
• The clincher rotation motor and the stapler rotation motor turn ON and rotate the stapler
/Rr and the clincher /Rr to the home position [5] after a specified period of time since the
trailing edge of the last paper passes the main tray paper exit sensor. The rotations are
stopped when the stapler rotation home sensor and the clincher rotation home sensor
turn ON. At the same time, the stapler movement motor turns ON [6], and it stops when
the stapler movement home sensor turns ON.
