1.2 Operation

1.2.1 Single sided original mode

A. Original feed operation

The paper feed system is driven by the paper feed motor (M301). The registration clutch (MC301) func-

tions as the brake to stop the registration roller, not to turn ON or OFF the drive force transmission.

When M301 turns ON, the paper feed roller is pressed against the original set to the original feed tray. the

original stopper goes up to the turnout position, and the paper feed roller and feed roller send the original

to the registration roller.

The original is struck against the reversing registration roller and M301 stops after the specified time. Thus,

a loop is formed before the registration roller to correct the skewed original.

After M301 stops, MC301 turns OFF to release the registration roller.

Then, M301 starts reversing operation, and the timing sensor (PS302) turns ON and stops after the speci-

fied time.

After that, M301 and conveyance motor (M302) start reversing at the same time to send the original to the

II UNIT EXPLANATION

conveyance belt (conveyance section).

After PS302 turns ON by the original sent as described above, M301 stops after the specified time.

D. Original reverse/paper exit operation

The reverse/paper exit system is driven by the reverse/paper exit motor (M303). Conveyance path is

switched by the paper exit solenoid (SD301) and reverse solenoid (SD302), both of which are OFF in this

mode.

Original from the conveyance section is wound around the reverse roller and sent to the reverse stocker.

When the reverse sensor (PS305) turns OFF, M303 starts decelerating and stops. Then M303 starts

reversing to send the original to the reverse/paper exit conveyance path. After the paper exit sensor

(PS306) turns ON, M303 decelerates after the specified time and reverses to exit the original to the origi-

nal stocker at a low speed.

After PS306 turns OFF, M303 stops after the specified time.

1.2.3 Original size detection

A. Normal copy mode

Main scanning direction is detected by the resistance value of the size VR (VR301) interlocked with the

guide plate position on the paper feed tray. Sub-scanning direction is detected by the combination of the

original size sensor/S (PS309) and original size sensor/L (PS310) when they are turned on and off.

B. Mixed original copy mode

Maximum original size in the main scanning direction is detected by the resistance value of the size VR

(VR301) interlocked with the guide plate position on the paper feed tray.

Sub-scanning direction is detected by the time when the original passes by the timing sensor (PS302).

Allowed size combinations are as shown in the table below.

1.2 Operation

1.2.1 Up/down plate control

The up/down plate in the LCT is driven by the wire.

When the upper cover and the front door are closed, the front door interlock switch (MS101) and the upper

cover interlock switch (MS102) turn on to supply 24VDC to the drive system and the up/down motor

(M100) turns on to lift the up/down plate.

The MS101 and the MS102 turn on/off 24V and the upper cover open/close sensor (PS100) and the lower

limit sensor (PS101) turn on/off the M100 control signal.

When the upper sensor (PS109) turns on and detects the upper limit of paper, the M100 turns off.

When paper is fed and the PS109 turns off, the M100 turns on to lift the up/down plate until the PS109

turns on again.

When the upper cover is opened, the PS100 turns off and the M100 rotates in reverse direction to lower

the up/down plate by 90mm.

After this, each time the tray down switch (SW100) is pressed, the up/down plate goes 90mm down and

stops at the position where the PS101 was turned on.

1.2.2 Paper feed control

The paper feed system is driven by the paper feed motor (M101).

The transmission of driving force to the paper feed unit (paper feed roller and feed roller) is controlled by

turning on/off the paper feed clutch (MC101). And the transmission of driving force to the conveyance roller

is controlled by turning on/off the pre-registration clutch (MC102).

When paper can be fed and the paper feed solenoid (SD100) turns off, the paper feed unit comes into con-

tact with paper to feed it to the conveyance roller. Then, the SD100 turns on and the paper feed unit is

detached from paper.

As a result of this operation, a loop is formed in front of the conveyance roller to correct the tilt of paper.

After completion of the tilt correction of paper, the MC102 turns on to feed paper to the 2nd paper feed sec-

tion of the main body.

Paper feed speed is 470mm/s at all times. The M101 stops after specified period of time after copy/print is

complete.

1.2.3 Paper feed assist fan control

Some of the side guides (at front and rear) are provided with a fan to assist the handling of paper while it

being fed. The fan turns on/off at the same timing as the paper feed motor (M101).

The auto-mode has been set when the machine was shipped from the factory, and this air assist turns on

when the coated paper is selected.

The 25 mode DIPSW allows the mode to be switched among "ON for coated paper only," "ON for all types

of paper" and "OFF at all times."

II UNIT EXPLANATION

1.2.4 Mis-centring adjustment control

In combination with the paper feed sensor (PS107), the mis-centering sensor (PS120) detects the position

of paper in conveyance. The image processing section uses this information for writing so that an original

to be read comes at the same position as paper.

The contact-type sensor of PS120 detects the paper edge position along the main scan, and the PS107

detects the leading edge of paper to be used for correction along the sub-scan.

[4] Remaining paper sensor /2 (PS103)

As paper gets reduced, the up/down plate goes up little by little. The actuator at the rear rotates in interlock

with this up drive.

The remaining paper is detected in eight steps in combination of the PS102 to the PS105 that are turned

on and off by the actuator.

When the PS108 turns on, no-paper detection is made with a message shown on the display of the main

body.

1.2 Operation

1.2.1 FNS conveyance control

The FNS conveyance is made by a 24 VDC motor by controlling the FNS control board (FNS CB).

A. Interlock control

The FNS conveyance drive control of paper is commenced by the start button ON signal from the main

body. However, when the interlock (MS701) is off, an error message is output to the main body PRCB with

no control commenced.

B. FNS conveyance control

In the mode in which a high speed rotation is made by turning on the start button and paper is exited at low

speed from the main body, turn on the main body paper exit sensor (PS13) to switch conveyance to a low

speed, and then to a high speed a specified period of time after the FNS entrance sensor (PS704) is

turned ON.

For main tray paper exit, conveyance is switched to a medium speed a specified period of time after PS704

detects the trailing edge of paper, and then maintained at the FNS paper exit line speed. And the convey-

ance returns to a high speed rotation after a specified period of time to stand by for the next conveyance of

paper.

FN-9/FN-120 Ver.1.0 Sep. 2003 CONVEYANCE

1.2.2 Gate drive control

The gate switches the paper conveyance path to the sub-tray, main tray or stacker.

A. Gate operation

To operate the gate, the gate drive motor (M712) [1] drives the gate cam [2], and the two cams (cams /U [3]

and /L [4]) of this gate cam drive the two gates of gate /U [5] and gate /L [6] respectively. The home posi-

tion is detected by the gate HP sensor (PS716) [7].

B. Gate control

The gate control is made by the FNS control board (FNS CB).

When an FNS operation signal from the main body turns on the gate, it stops at either one of the sub-tray

(home position) [1], stacker [2] and main tray [3]. However, while in the paper exit to the sub-tray, the gate

does not operate because of the home position being already set to the sub-tray.

After completion of copy, it stops when the gate HP sensor (PS716) detects the home position.

1.2.3 By-pass gate control

The by-pass gate is provided at the paper path to the stacker section. This is a gate to obtain a high pro-

ductivity by conveying paper while in stapling with no time wasted.

A. By-pass gate operation

The by-pass gate [1] is driven by the by-pass gate solenoid (SD705) [2].

For small size paper (A4, B5, 8.5 x 11), the by-pass gate operates on only the first pages of the second

and succeeding copies and sends them to the by-pass route [3]. The second pages of the second and

succeeding copies are sent into the normal route [4], and the first pages are put upon the second pages to

be conveyed to the stacker together.

B. By-pass gate control

The by-pass gate operates only for small size paper (A4, B5, 8.5 x 11) in the staple mode. The by-pass

gate solenoid (SD705) is controlled by the FNS control board (FNS CB).

(1) For the first copy

The by-pass gate solenoid (SD705) does not operate while in the paper passage of the first copy.

(2) For the second copy

A specified period of time after the stapling operation of the first copy turns on, the by-pass gate solenoid

(SD705) turns on to pull in the first paper of the second copy to the by-pass side.

It turns off a specified period of time after the FNS entrance sensor (PS704) detects the trailing edge of the

first paper of the second copy.

SD705 does not operate while in the conveyance of the second and succeeding papers.

FN-9/FN-120 Ver.1.0 Sep. 2003 CONVEYANCE

(3) For the third and succeeding copies

A specified period of time after the FNS entrance sensor (PS704) detects the trailing edge of the last paper

of the second copy, the by-pass gate solenoid (SD705) turns on to pull in the first paper of the third copy to

the by-pass side.

It turns off a specified period of time after PS704 detects the trailing edge of the first paper of the third

copy.

1.2.4 Shift control

The shift roller is driven by the FNS conveyance motor (M701) to convey paper to the main tray.

A. Shift operation

When the shift motor (M702) [2] rotates while in the paper conveyance to the main tray [1], the crank

mechanism [3] shifts the entire shift moving section [5] including the shift roller [4] about 30 mm to the rear

side to shift and move paper for exit.

The shift position is detected by the shift HP sensor (PS718) [7].

In the sort/group mode, the shift motor (M702) turns on a specified period of time after the FNS entrance

sensor (PS704) detects the trailing edge of paper. M702 rotates to start to shift the shift moving section.

The shift roller rotates by driving the FNS conveyance motor (M701), and it shifts while conveying paper.

When the shift HP sensor (PS718) turns on from off and it is detected that the shift has been completed,

M702 stops.

A specified period of time after it stops, M702 turns on again and stops at the position where PS718 turned

off from on. This operation returns the shift moving section to its original position to stand by for the next

page to be shifted.

Paper is offset one at a time by repeating a series of this operation.

The paper exit roller motor (M707) controls the main tray paper exit roller and the paper exit belt of the

stacker by controlling the FNS control board (FNS CB).

A. Straight/sort/group modes

When the FNS entrance sensor (PS704) detects the leading edge of paper, the paper exit roller motor

(M707) rotates at high speed. And a specified period of time after PS704 detects its trailing edge, the rota-

tion changes to a low speed for paper exit.

To convey the next paper, the rotation changes again to a high speed a specified period of time after the

main tray paper exit sensor (PS706) detects the trailing edge of paper.

A specified period of time after PS706 detects the last paper, M707 stops.

Since its rotation is slower than that of the conveyance roller, the paper exit roller releases the nip function

except while in paper exit. However, when paper reaches the paper exit opening, it drives the nip moving

section to nip the paper.

A. Paper exit opening nip operation

When paper reaches the paper exit opening, the paper exit opening solenoid (SD704) [1] drives the nip

moving section [2] and presses the nip roller [4] against the main tray paper exit roller [3] to nip the paper

and discharge it to the main tray [5]. The main tray paper exit sensor (PS706) [6] detects the paper being

discharged.

1.2.7 Open/close control of the paper exit opening

Since paper protrudes in the staple (when the length of the paper feed direction is over B5R), booklet and

three-folding modes, the paper exit opening opens from the start of copying until the completion of sta-

pling.

A. Open/close operation of the paper exit opening

The open/close of the paper exit opening rotates the paper exit opening motor (M708) [1] and the crank

mechanism [2] raises the entire paper exit opening unit [3] to open the paper exit opening. The paper exit

opening HP sensor (PS712) [4] detects the open/close of paper exit opening.

1.2.8 Sub-tray paper exit control

The sub-tray paper exit roller is driven by the sub-tray paper exit motor (M721) and controlled by the FNS

control board (FNS CB).

A. Sub-tray paper exit (M721) control

The sub-tray paper exit motor (M721) starts to rotate at high speed the moment sub-tray paper exit sensor

(PS701) detects the leading edge of paper.

A specified period of time after the FNS entrance sensor (PS704) detects the trailing edge of paper, the

rotation changes to a low speed. M721 stops a specified period of time after PS701 detects the trailing

edge of paper.

B. Sub-tray full detection

When a specified amount of paper is stacked in the sub-tray, the sub-tray full (PS719) turns on with a "Sub-

tray full" information sent to the main body. The main body then displays a message on the operation

panel.

2.2 Operation

2.2.1 Tray up/down control

A. Tray up/down operation

The up/down wire is wound up by the driving force of a worm gear provided on the shaft of the tray up/

down motor (M703).

The main tray goes up or down depending on the wind-up direction. The main tray goes up when the up/

down pulley /L rotates clockwise as seen from the front, and goes down when it rotates counterclockwise.

B. Paper detection

The tray upper limit sensor (PS702) and the stapler paper exit upper limit sensor (PS707) maintain the dis-

tance between the top face of paper in the main tray (the top face of the main tray when there is no paper

exit) and the paper exit opening constant to prevent uneven paper exit.

While in continuous copy, FNS soft counts the number of sheets discharge, and copy stops when it

II UNIT EXPLANATION

reaches the maximum loading capacity for each paper size.

However, when discharged paper is removed while in copy, the tray goes up and the counter reset sensor

(PS715) turns on.

This resets the soft counter, thus allowing an unlimited paper exit.

The tray lower limit sensor (PS703) detects the lowest limit of the tray. And while in intermittent copy,

PS703 is used to control the number of copies since the total number of sheets are not accumulated in the

soft counter.

C. Tray up/down control

The up/down operation of the main tray is made by the clockwise or counterclockwise rotation of the tray

up/down motor (M703). M703 is controlled by the FNS control board (FNS CB).

(1) Non sort/sort/group modes

An FNS operation signal from the main body allows the tray up/down motor (M703) to raise the tray until

the tray upper limit sensor (PS702) turns on.

When paper passes through the main tray paper exit sensor (PS706), M703 lowers the tray. A specified

period of time after PS702 turns off, M703 raises the tray again and stops it when PS 702 turns on.

Repeat the above for each paper.

3.2 Operation

3.2.1 Alignment /U control

In the staple, folding, stitch-and-fold, and three-folding modes, the alignment along the width of paper con-

veyed to the stacker is made by rotating the alignment motor /U (M705) in normal or reverse direction to

open or close the alignment plate /U. The alignment HP sensor /U (PS708) detects the home position of

the alignment plate /U.

II UNIT EXPLANATION

A. Alignment /U control

An FNS operation signal from the main body starts to rotate the alignment motor /U (M705) in the direction

in which the alignment plate /U closes and stops at the stand-by position in which the alignment plate is

open a little wider then the paper width.

A specified period of time after the stacker entrance sensor (PS705) detects the trailing edge of paper,

M705 rotates in the normal or reverse direction to oscillate the alignment plate /U for proper alignment of

paper. Alignment is made each time a sheet of paper is sent in.

made by oscillating the alignment plate /U and the alignment plate /L.

The alignment plate /L is oscillated by rotating the alignment motor /L (M716) in the normal or reverse

direction. The home position of the alignment plate /L is detected by the alignment HP PS/L (PS724).

A. Alignment /L control

In the folding, stitch-and-fold and three-folding modes, an FNS operation signal from the main body starts

to rotate the alignment motor /L (M716) in the direction in which the alignment plate /L closes. And the

motor stops at the stand-by position in which the alignment plate /L opens a little wider than the paper

width.

A specified period of time after the stacker entrance sensor (PS705) detects the trailing edge of paper,

FN-9/FN-120 Ver.1.0 Sep. 2003 STACKER

A. Stopper operation

The booklet stopper and the flat-stapling stopper are interlocked by the link mechanism. When the booklet

stopper goes down, the flat-stapling stopper is released.

The stopper motor (M718) moves the booklet stopper, and its home position is detected by the stopper HP

sensor (PS723).

When the booklet stopper [1] is at the home position, the flat-stapling stopper [2] is set by the pressure of

the spring [3]. In the staple mode (flat stapling), stapling is made in this condition.

When the booklet stopper [1] goes down, the spring [4] in the link mechanism releases the flat-stapling

stopper with paper arranged properly by the booklet stopper.

3.2.4 Stacker entrance conveyance control

The stacker entrance motor (M713) drives the stacker entrance roller and the swing belt to convey paper to

the stacker, arrange properly the trailing edge of paper, and adjust the stand-by timing for stapling.

A. Stacker entrance operation

A stacking method with a tilt angle of approx. 70 degrees is employed to realize a compact equipment. A

corrugation roller is employed for the stacker entrance roller [1] to support the paper exit to the stacker. The

proper arrangement of paper in the stacker is made by the paper's own weight and the swing belt [2].

To support the proper arrangement of the trailing edge of paper when curled, for stacking more than ten

sheets of paper, the stacking assist roller [3] is not only rotated and driven by the stacking assist motor

(M722) but also pressed by the stacking assist solenoid (SD702).

B. Paper exit arm control

(1) Staple mode (When the vertical length is shorter than B5R)

When the stapling operation is completed, the paper exit roller motor (M707) rotates to drive the paper exit

belt of the stacker section. This causes the paper exit arm to hook the paper to raise it up to the paper exit

roller. And then, the paper exit roller discharges the paper to the main tray. When the paper exit belt HP

sensor (PS709) detects the change from off to on, M707 stops.

(2) Staple mode (Other than the above)

When the paper size is other than the above, the paper exit opening is open.

When the stapling is completed, the paper exit opening motor (M708) operates. When the paper exit open-

ing HP sensor (PS712) detects a fact that the paper exit opening is fully closed, the paper exit roller motor

(M707) rotates to drive the paper exit arm of the stacker section. This causes the paper exit arm to hook

the paper to raise it up to the paper exit roller. And then the paper exit roller discharges the paper to the

main tray.

When the paper exit belt HP sensor (PS709) detects the change from off to on, M707 stops.

B. Stapler rotational movement operation

Because of one corner stapling at rear, the stapler /R and the clincher /R rotate 45°.

The rotational movement of the stapler /R is made by the stapler rotation motor (M706) and the rotational

movement of the clincher /R made by the clincher rotation motor (M704).

The stapler is securely locked by the ball [1] and spring [2] of the ball lock mechanism at the angle of rota-

tion of 0°and 45°. Fig. [3] shows the locked condition, and Fig. [4] shows the unlocked condition.

4.2.2 Staple control

Stapling is made by the stapler motors /R and /F (M709 and M714) and the clincher motors /R and /F

(M710 and M715).

A. Stapling operation

In the stapling operation, the cam mechanism allows the stapler motors /R and /F (M709 and M714) within

the staplers /R and /F [1] to push out the paper presser [3] to the clincher side [4] to press the paper [5],

and then push out the staples [6]. After that, the clincher motors /R and /F (M710 and M715) in the clinch-

ers /R and /F bend the staples [6].

B. Staple control

(1) Staple

After completion of the alignment operation of the alignment plate, the stapler motors /R and /F (M709 and

M714) start the stapling operation. After a specified period of time, the clincher motors /R and /F (M710

and M715) start the clinching operation.

When the clincher HP sensors /R and /F (PS732 and PS733) and the stapler HP sensors /R and /F

(PS730 and PS731) detect the home position (OFF to ON), the stapling operation is completed.

(2) Detection of staple-jamming

While in the stapling operation, if the stapler HP sensor /R and /F (PS730 and PS731) and the clincher HP

sensors /R and /F (PS732 and PS733) do not turn on within a specified period of time after they turn off, it

seems that staples have been jammed. Rotate reversely the stapler motors /R and /F (M709 and M714)

and the clincher motors /R and /F (M710 and M715) and return them to the home position.

(3) Cartridge detection

The presence of a cartridge and its proper setting are detected by the cartridge switches /R and /F

(SW701 and SW703) within the stapler.

If no cartridge is found or if a cartridge is improperly set, an error message is shown on the main body

LCD.

(4) Staple detection control

When staples run out, the stapler SW /R and /F (SW702 and SW704) turn on with an error message

shown on the main body LCD.

5.2.3 Three-folding gate control

The three-folding gate switches between the folding/stitch-and-fold path and the three-folding path. The

three-folding gate is driven by the three-folding gate solenoid (SD706).

A. Second folding operation of the three-folding

The three-folding gate solenoid (SD706) drives the three-folding gate [1] to switch the paper path to the

three-folding path and guide the paper [3] discharged from the folding roller [2] to the three-folding stopper

[4].

A sheet of paper that runs up against the three-folding stopper is made into a loop [5] which is drawn in

between the folding roller and the three-folding roller [6]. This loop of paper, which is being pressed by the

folding roller and the three-folding roller, is folded to make the second folding and then discharged to the

booklet tray [7].

The folding position of the second folding depends on the position of the three-folding stopper.
