(Operation of stapling)

1) The jog plates are moved to the stand-by position before the

paper is fed to the staple tray.

2) Immediately after the paper is fed into the staple tray, the jog plate

is moved to the paper size position to ensure the alignment of the
paper.

1) The stapler unit is moved to the stapling position.

– The number of sheets to be stapled is fed to the staple tray –

2) The pusher (the sheets to be stapled) is lowered the stapling

position.

3) The paper is stapled ... (in the case of 2-point stapling, the action

that is described on the following page is added.)

4) The pusher (the sheets stapled) is elevated to the paper dis-

charge position.

5) After the job, the stapler unit is returned to the home position.

1) The pusher is elevated to the position which makes it possible for

the staple unit to move. 

2) The staple unit is moved to the staple position where the 2nd

staple is driven.

3) The pusher (sheets to be stapled) is lowered to the stapling posi-

tion.

4) Sheets are stapled.

5) The staple unit is returned to the 1st staple position.

(After the job is finished, the staple unit is returned to the home
position.)

When the off-set motor (3) is driven, the tray is shifted sidewise
against the direction in which the sheets are delivered, so that the
sheets discharged into the off-set tray (1) are sorted by the specified
number of sheets. The rotation is unidirectional and controlled by the
crank. The motor is braked to a stop by the off-set home position
sensor (2) turning ON.
