(1) Stapling mode for paper sized A4R and above

The paper exit opening is opened from the time copy­ing commences to the time stapling is complete.

(2) Paper exit of the staple mode

When the stapling has finished, the paper exit open­ing is closed, the paper gripped and exited to the main
tray. The opening and closing of the paper exit open­ing is performed by the paper exit opening motor (M8).

Paper exit
opening motor

(3) Pressure of the paper exit roller

The paper exit roller rotation is slower than the con­veyance rollers A, B and C. Therefore pressure is re­leased at times other than when paper is exiting.
When the paper reaches the paper exit opening the
paper exit roller applies pressure and paper is exited
to the main tray. The pressing and releasing of paper is
performed by the paper exit opening solenoid (SD4).

6. Intermediate conveyance roller

In this machine, in order to be compatible with thick paper ,
it has its pressure of the intermediate conveyance roller
set at a slightly higher level.
While in conve yance collectively of the 1st and 2nd copies
of the 2nd set and later to the stacker in staple copy mode
for small-sized paper, the decompression solenoid (SD3)
is operated to lower the pressure of the intermediate con­veyance roller.
This is to prevent dirt from the roller from sticking to the
paper and wrinkles from taking place on paper in convey­ance.

(1) Main tray paper exit operation

M1 (1st conveyance) turns ON by the ON signal of the
start button and goes OFF after the specified time
when PS4 (FIN entrance path) detects the trailing edge
of the final copy.

(2) Sub-tray paper exit operation

M1 turns ON by the ON signal of the start button, and
rotates at high speed. When PS4 (FIN entrance path)
detects the trailing edge of the paper, rotation switches
to low speed after the specified time. Then, rotation
once again returns to high speed to be ready for
conveyance of the next copy. On detection of the
trailing edge of the final copy by PS4, it turns OFF in the
specified time.

b. During Staple Mode

(1) ON timing of M4 (2nd conveyance)

M4 (2nd conveyance) goes ON by the ON signal of
the start button, and rotates at high speed. When PS4
(FIN entrance path) detects the trailing edge of the
paper fed from the main body, rotation switches to low
speed after the specified time.
Then, rotation once again returns to high speed to be
ready for conveyance of the next copy.

(2) Paper conveyance of the 1st copy of the 2nd and later

sets
When PS4 (FIN entrance path) detects the trailing edge
of the 1st copy fed from the main body, it goes OFF
after the specified time, and enters a standby mode to
convey the 2nd copy.
As a result, the 1st copy is conveyed to the stacker
entrance.

(3) Paper conveyance of the 2nd copy of the 2nd and later

sets
When PS4 detects the trailing edge of the 2nd copy,
M4 starts to rotate at high speed after the specified
time. Then, in the specified time from detection of the
trailing edge of the 2nd copy by PS4, M4 is switched
over into low speed rotation.
Further, in the specified time, it once again returns to
high speed rotation which is the standby state for con­veyance of the 3rd copy and later.
For the 3rd copy and later, rotation is switched over
into low speed in the specified time after the trailing
edge of the copy is detected by PS4, and is returned
to high speed in the specified time.

(4) OFF timing of M4 (2nd conveyance)

M4 turns OFF in the specified time after PS6 (paper

Paper is fed to the main tray via the stacker. At this time,
the paper passes the sub-tray gate, gate, and the b y-pass
gate as its convey ance path. Among these gates, the sub­tray gate is installed so that the stack er side becomes the
convey ance path beforehand, thus SD2 does not oper ate.
(1) SD1 (gate) ON timing

SD1 goes ON by the ON signal of the start button,
switches the gate to the stacker side, and enter a
standby mode for paper conveyance.

(2)

Paper conv ey ance f or paper in sizes other than A4/B5
Paper in sizes other than A4/B5 is conveyed to the
stacker side by the gate. At this time, SD5 does not
operate and the paper is fed to the stacker entrance
roller.

(3) A4/B5 sized paper conveyance (Conveyance of the

1st copy of the 2nd and later batches)
For conve y ance of A4 or B5 sized paper, in the speci­fied time after the trailing edge of the final copy of the
preceding set is detected by PS4 (FIN entrance path),
SD5 is turned ON, switching the bypass gate into By­pass. The 1st copy of the following set is, therefore,
guided into the bypass track.

(4) A4/B5 sized paper conveyance (Conveyance of the

2nd copy of the 2nd and later sets)
In the specified time after the trailing edge of the 1st
copy is detected by PS4, SD5 turns OFF, closing the
bypass gate.
The 2nd copy, therefore, follows the normal course,
which is conveyed to the stacker entrance roller to­gether with the 1st copy held in the bypass track.
The 3rd copy and later are conv e y ed to the stacker in
the normal course, where SD5 never turns ON.

that the shift unit side becomes the conve yance path dur­ing idling state, so SD2 (sub-tray paper exit) and SD1 (gate)
which drive each gate do not operate.

Through repetition of these operations, sheets of pa­per are carried successively to the stacker section.

(2) OFF timing of M14

M14 turns OFF in the specified time after PS6 (paper
exit 1) detects the final batch stapled.

b. Conveyance operation to the stacker (A4/B5

sizes)

(1) Paper conveyance for the 1st set

A4/B5 sized sheets of paper for the 1st batch to staple
are fed in the same way as those other than A4/B5
sized.

(2) Paper conveyance of the 1st copy of the 2nd and later

sets
M14 turns OFF in the specified time after the trailing
edge of this paper is detected by PS4 (FIN entrance
path). The 1st copy, therefore, is held in standby in
the by-pass track so that paper of the 2nd set is not
conveyed to the stacker section before completing to
staple the first set.

(3) Paper conveyance of the 2nd copy of the 2nd and later

sets
M14 turns ON again in low speed in the specified time
after the trailing edge of this paper is detected by PS4.
Therefore, the 1st and 2nd copies are collectively con­veyed to the stacker section as being piled up. In the
specified time after PS5 (stacker conveyance path)
detects the trailing edges of the 1st/2nd copies, M14
changes into high speed rotation, entering standby
state for conveyance of the following copy.
The 3rd and later copies are conveyed to the stacker
section in the same manner as that for the 1st.

c. Operation for justifying the trailing edge of the

Paper shift for sort and group modes is performed by M2
(roller shift). The control of M2 is performed by the FNS CB
(FNS control board).

1. Operation

In the specified time after the trailing edge of the paper
subject to shifting is detected by PS4 (FIN entrance path)
in Sort/Group mode, M2 (roller shift) turns ON.
Rotation of M2 starts shifting of the conveyance slide shaft.
The conveyance slide shaft is rotated by M4 (2nd convey­ance) driving, which shifts as conveying paper.
When PS18 (roller shift HP) turns ON and detects comple­tion of shifting of the conveyance slide shaft, M2 turns OFF
and is brought to a stop.
In the specified time from turning OFF of PS4, M2 turns ON
once again, returning the conveyance slide shaft to the
original position. When PS18 turns OFF and the convey­ance slide shaft returns fully to the original position, M2 is
brought to a stop, where it waits for the next paper subject
to shifting.
Through repetition of these operations, sheets of paper are
shifted and conveyed to the paper exit roller.

Paper exit from the stacker is performed by the paper exit
belt, and paper exit from FNS is performed by the paper exit
roller. They are driven by M7 (paper e xit roller). The control of
M7 is performed by the FNS CB (FNS control board).

1. Operation
a. Sort/Group/Non-sort mode

M7 (paper exit roller) rotates by the ON signal from the main
body start button.
PS23 (paper exit 2) detects the exiting of paper and if no
finisher start signal comes from the main body, it will stop.

b. Staple mode

The staple mode commences rotation with completion of
the stapling operation. It will stop when the PS9 (paper exit

M11 (stapler movement) and M12 (stapler rotation) move the
stapler to the fixed position corresponding to the stapler mode,
and paper is stapled by the rotation of M9/M10 (stapler R/F).
PS15 (stapler R HP) and PS17 (stapler F HP) switch ON-OFF­ON, and detect one cycle of the stapler movement. These are
controlled by the FNS CB (FNS control board).

1. Operation
a. Stapler one position movement control

Step motor M11 (stapler movement) turns ON by the ON
signal from the main body start button and the stapler is
moved to the fixed position that differs depending on paper
size and then stops. When the staple one position mode is
complete, M11 (stapler movement) moves the stapler and
it stops in the PS11 (stapler movement HP) ON position
(inside most).

1 - 38

FS-106

b. Stapler two position movement control

Through the ON signal from the main body start button the
stapler is rotated by M12 (stapler rotation) so that the
stapler is parallel to the paper and then stops. At this time,
PS22 (stapler rotation HP2) is ON. When the stapler two
position mode is complete, M12 (stapler rotation) rotates
the stapler and it stops in the PS21 (stapler rotation HP1)
ON position (diagonal position).

c. Stapler movement control

Once the alignment plate is closed, M9 (stapler R)/M10
(stapler F) rotate and the staple push out plate drives the
staples in. When PS15 (stapler R HP) and PS17 (stapler F
HP) detects the home position (OFF-ON) and M9/M10
stop.
While the stapler is stapling, if within 500 ms from when
PS15/PS17 turn OFF they do not come ON again it is
judged as a staple jam. When the door is opened and
closed, M9/M10 rotate in reverse and return to the home
position (PS15/PS17 turn ON).

d. No staple detection control

PS14 (stapler R no staples) and PS16 (stapler F no staples)
detect that there are no staples in the staple cartridge.
After supplying the staples, M9/M10 rotates until PS24
(stapler R ready) / PS25 (stapler F ready) goes ON by the
staple, and prevents miss stapling.
