MX-FN25 MECHANISM 3 – 6
C. Stapler
The stapling operation is performed by the drive motor in the sta-
pler. When an overload of the motor is generated by a staple jam,
etc., “Staple jam” is displayed on the operation panel.
The stapler is provided with the cartridge set sensor and the staple
end sensor. When they are OFF, the staple supply message is dis-
played on the operation panel.
When staple end occurs during copying, the job is completed and
the staple supply message is displayed.
When a staple jam occurs, copying is stopped.

D. Stapler shift mechanism
The stapler shifts horizontally or rotates to make stapling according
to the four staple modes.

to the four staple modes.
1)
Staple shift mechanism
The stapler is supported by the rod, and shifted horizontally by
the timing belt. When the copy start key is pressed, the jogger
fence moves to the standby position. Then the stapler shift
motor turns ON to shift the stapler to the stapling position, and
the stapler enters the standby state of stapling.
The shift quantity differs depending on the paper size and the
stapling position.
When stapling at two positions, the front side is stapled first,
then the rear side is stapled.
The stapler is supported by the rod, and shifted horizontally by
the timing belt. When the copy start key is pressed, the jogger
fence moves to the standby position. Then the stapler shift
motor turns ON to shift the stapler to the stapling position, and
the stapler enters the standby state of stapling.
The shift quantity differs depending on the paper size and the
stapling position.
When stapling at two positions, the front side is stapled first,
then the rear side is stapled.
2)
Staple rotating mechanism
In one-position diagonal staple mode, the stapler is shifted hor-
izontally and then rotated diagonally. Then stapling is per-
formed. Rotation is made by the stapler rotation motor.

E. Rear edge holding mechanism
In the edge binding or the center binding bookmaking mode (MX-
FNX7 only), curls and slacks on paper stacked to the rear edge ref-
erence fence are pressed to the staple tray, allowing the next paper
to feed to the rear edge reference fence, improving the alignment
accuracy when binding.

to feed to the rear edge reference fence, improving the alignment
accuracy when binding.
1)
When stacking paper to the rear edge reference fence (staple
tray), paper is first aligned by the jogger fence (horizontal
alignment), then aligned by the shift roller (vertical alignment).
When the horizontal alignment and the vertical alignment are
completed, the oscillation SOL is turned ON to move the rear
edge guide to the holding position via the arm.

When the horizontal alignment and the vertical alignment are
completed, the oscillation SOL is turned ON to move the rear
edge guide to the holding position via the arm.
2)
When the next paper enters the staple tray, the SOL is turned
OFF to save the rear edge guide to the standby position. After
completion of alignment operation, the SOL is turned ON again
to hold the rear edge section of paper.

The above operations are repeated until the last paper and
binding are completed. When binding operation is completed,
the SOL is turned OFF to save the rear edge guide to the
standby position until the next job is started.
