7) The first set is discharged.

8) The first sheet, the second sheet, and the third sheet of the
second set are discharged together to the staple tray.

6. Rise-fall mechanism

<Tray assembly>

The Tray assembly rises or falls depending on the copy paper
quantity (paper stack height) discharged on the tray. The height is
always adjusted by the OFF state of the paper surface sensor.

• When discharging in the shift mode:

Paper surface sensor on the end fence side

• When discharging in the staple mode:

Paper surface sensor on the filler

Filler paper surface sensor

Lift motor

1) Falling operation

When the discharged copy paper is loaded on the tray and the
filler is lifted to turn on the paper surface detection sensor
lower for 3 sec or more, the lift motor rotates to fall the shift
tray. The falling operation varies depends on the mode.

Staple:

The lift motor rotates for a certain time to lower the tray height
for a certain interval, adjusting the height.

Shift:

The shift tray lifts up to the position where the paper surface
sensor is turned on. Then, the tray falls to turn off the paper
surface sensor, adjusting the height.

The shift tray full detection is made when the sensor is turned
on and it is displayed on the operation panel, and copying is
stopped. Cancel is made by removing copy paper.

2) Rising operation

When copy paper is removed from the shift tray and the paper
surface sensor upper is turned on, the shift tray rises. It stops
when the sensor is turned off.

7. Staple jogger mechanism

A. Stack mechanism

Copy paper branched to the staple tray is transported to the staple
tray. After the staple paper exit sensor turns off (A4Y), the align­ment roller SOL turns on for a certain time (varying depending on
the size and the quantity). The alignment roller pushes paper to the
tray stopper to align the rear edges of paper.

B. Jogger mechanism

Copy paper rear edges are aligned by stack operation of (A), then
copy paper side edges are aligned by jogger operation.
First, the jogger fence closes to 7mm open from the right and the
left edges of paper by the ON signal (copy start).
When the lead edge of the transported paper passes the staple
paper exit sensor, the jogger fence closes 5mm to receive paper
and performs the operation of (A) to align the rear edges.
Then, the jogger fence closes 2.6mm furthermore to align the side
edges.
When the jogger operation is completed, the jogger fence opens
again to 7mm open from the paper edges and the machine enters
the standby state of the next paper.

C. Stapler

The stapling operation is performed by the drive motor in the sta­pler. 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 dis­played 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.

Staple hammer

D. Stapler shift mechanism

The stapler shifts horizontally or rotates to make stapling according
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.

2) Staple rotating mechanism

In one-position diagonal staple mode, the stapler is shifted hor­izontally and then rotated diagonally. Then stapling is per­formed. Rotation is made by the stapler rotation motor.

E. Rear edge holding mechanism

In the edge binding or the center binding bookmaking mode (MX­FNX7 only), curls and slacks on paper stacked to the rear edge ref­erence 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.

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.

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.

3) 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.

F. Center binding holding mechanism

Discharge fence 1

First set paper bundle

Discharge fence 2

(MX-FNX7 only)

In the center binding bookmaking mode, curls and slacks on paper
stacked on the staple tray are pressed to the staple tray side,
improving the paper edge detection accuracy and preventing paper
bundle shift when binding.

1) In the center binding bookmaking mode, paper is stacked to
the staple tray and vertical alignment and horizontal alignment
are completed. Then, paper bundle is transported to the center
binding stapler position at the center of the staple tray, and the
paper bundle rear edge is detected by the photo sensor.

The paper bundle is stopped according to the detection infor­mation, and binding is performed.

2) During these operations (after completion of horizontal/vertical
alignment, transport of paper bundle to the center binding posi­tion, completion of binding - *), the holding SOL is turned ON,
and the roller is moved to the holding position via the arm to
hold the paper bundle.

3) After completion of binding, the holding SOL is turned OFF to
save the roller to the standby position until the next job is
started.

* When the paper for center binding bookmaking is A3T, B4T, DLT,

or LG size, in order to detect the paper bundle rear edge with the
photo sensor, the paper bundle is moved up and down (normal/
reverse operation) inside the staple tray. When in reverse opera­tion (moving down), the holding SOL is turned OFF to save the
roller in order not to prevent reverse operation of the paper bun­dle by the roller.

8. Center binding staple mechanism (MX-FNX7 only)

1) The first set is transported to the center binding staple section.

2) The center binding stapling of the first set is completed.

6) The first set folding is completed and discharged. At the same
time, the second set center binding stapling is completed.

5) The folding plate advances and the folding roller rotates to fold
the first set at the center. At the same time, transporting of the
second set to the center binding staple position is completed.

Folding plate

9. Discharge mechanism

After completion of stapling, the discharge motor turns ON to drive the discharge belt, discharging copy paper from the staple tray with the dis­charge fence attached to the belt.

At that time, the paper exit guide plate remains in the open state until the paper bundle lifted by the discharge pawl moves by a certain distance
from the paper exit roller.

Then, the paper exit guide closes and the paper bundle is discharged to the shift tray by the paper exit roller.

The paper exit guide plate is opened or closed by rotation of the cam caused by the rotation of the paper exit guide plate open/close motor to
move the link up and down.

When discharging paper to the shift tray, the discharge motor is stopped for 300ms to prevent excessive pushing up.

After temporary stopping, the discharge motor is driven again and stops under the state where the discharge fence turns on the home position
sensor filler.

There are two discharge fences to improve productivity of small-lot binding.

LEAD-FREE SOLDER

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.

The alphabet following the LF mark shows the kind of lead-free solder.

Example:

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread.

Never use conventional lead solder thread, which may cause a breakdown or an accident.

Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after completion of soldering work.

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine file.
