ORIGINAL CONVEYANCE PROCESS

RADF

The RADF consists of a original feed section, conveyance section, reversal section, original exit reversal section, original exit tray (large), and original exit tray (small).

Original feed section

Original exit tray

Conveyance section

Reversal section

Slit glass (Read section)

The original placed faced up on the original feed tray is fed from the topmost original. The fed original is not conveyed to the original glass. Instead, it is read when it passes the slit glass placed in the conveyance path. The RADF operation consists of (a) single side original copy mode, (b) double side original copy mode, (c) mixed original copy mode and Z fold mode. Each has a different conveyance path. The conveyance path also depends on the original size.

)

[1] Single side original copy mode (latge)

(single side to single side copy, single side to double side copy) The original set in the original feed tray is fed by the original feed roller and separation roller until PS306 (original registration detection) turns on.

1. Original registration detection PS (PS306

2. Separation roller

3. Original feed roller

4. Registration roller

When PS306 turns on, the registration roller prefeeds the original and original is rapidly conveyed to the conveyance roller. The speed of the conveyance roller changes to scan speed at predefined interval after PS306 turns ON and feeds the original over the slit glass. At this point, if the next original is present, it is pre-fed as soon as PS306 detects its leading edge.

4. Slit glass

The original is read when it passes over the slit glass. The original that has been read is conveyed along the circumference of the conveyance roller by the opening of the flapper, goes through original exit roller 1, and is exited to the original exit tray (large).

[2] Single side original copy mode (small)

(single side to single side copy, single side to double side copy) The original feed and conveyance actions up to scanning are performed in the same manner as for single side original copy mode (large). The original that has been scanned is fed to the original reversal unit by the reversal roller because the flapper is closed and the paper exit path is blocked. The original fed to the reversal unit passes through the original exit roller 2 and is exited to the original exit tray (small) since the original exit gate is closed.

[3] Double side original copy mode (large)

(double side to single side copy, double side to double side copy) The original conveyance action up to the start of scanning of the front side of the first double side original is the same as for single side original copy mode (large). The original that has been scanned and read on the front side is fed by the reversal roller to the reversal unit since the flapper is closed and the original exit path is blocked. The original fed to the reversal unit does not fit in the reversal unit so the original exit gate opens to feed it to the original exit reversal section.

1. Original exit reversal roller

2. Original exit gate

When the original reversal detection PS (PS309) detects the trailing edge of the original and turns off, the reversal roller changes direction and feeds the original in the reversal section to the conveyance roller. Since the original is passed over the surface of the flapper, it is sent to the conveyance roller with sides reversed. The original reaching the conveyance roller does not exit the reversal roller so the pressure roller is released. The conveyance roller feeds this original over the slit glass for scanning.

3. Reversal roller

4. Flapper

The original that has completed scanning of the back side is fed inside the reversal unit once again since the flapper is closed. When PS309 detects the trailing edge of the original and turns off, the reversal roller changes direction and feeds the original in the reversal unit to the conveyance roller. Since the flapper is now opened, the original is fed along the flapper, passes through original exit roller 1, and is exited to the original exit tray (large).

[4] Double side original copy mode (small)

(double side to single side copy, double side to double side copy) The original conveyance action up to the start of scanning of the back side is the same as double side original copy mode (large). The original that has been scanned and read on the back side is fed by the reversal roller to the reversal section since the flapper is closed and the original exit path is blocked. Then the original exit gate opens and the original is fed to the original exit reversal section.

1. Original exit reverse detection PS (PS313)

2. Original exit reversal roller

When PS313 (original exit reverse detection) detects the trailing edge of the original and turns off, the original exit reversal roller changes direction and feeds the original to the original exit gate. Since the original exit gate is closed, the original passes over the original exit gate and is exited from the original exit roller 2 to the original exit section (small) with sides reversed.

[5] Mixed original copy mode

The mixed original copy mode supports both the same series originals and different series originals. However, since the size of the original in the conveyance direction is determined by the ON interval of PS306, size detection is performed prior to scanning.

The subsequent operations are the same as other copy modes.

riginal feed is performed by the original feed roller and separation roller driven by M302 (original feed). Original conveyance is performed by the original conveyance roller driven by M301 (original conveyance). M301 and M302 are controlled by DFCB (RADF control board).

1. Operation

a. Sensor activation at power ON

When SW1 (main) is ON, a sensitivity adjustment for PS306 (original registration detection), PS308 (original conveyance detection), PS311 (original skew detection 1) and PS312 (original skew detection 2) are performed. However, automatic adjustment is not performed when the RADF jam access cover is opened and MS301 (cover open/close MS) is OFF or when there is original inside the RADF.

b. Pressing original against roller

(1) First original

When a control signal is received from the main body, M303 (tray up/down drive) turns forward to raise the original feed tray. By this moment, the original is raised and pressed against the original feed roller. After PS315 (tray upper limit detection) turns ON, M303 stops after a predefined interval and leaves the original feed tray raised in standby state. After M302 feeds the first original, M303 rotates backward after a predefined time has elapsed since it stopped, lowering the original feed tray, and the pressure on the originals is released. M303 continues to rotate backward for a predefined interval and then stops and remains in standby state. At this point the original feed tray waits without lowering to the bottom.

(2) Second and subsequent originals

When PS308 (original conveyance detection) detects the leading edge of the first original and turns ON, M303 that was in standby turns forward to raise the original feed tray and presses the original against the original feed roller. Subsequent operations are the same as for the first original.

c. Original feed

M302 drives the original feed roller and separation roller. When a control signal from the main body is received, M302 rotates forward at low speed, stops, and goes into standby. When the original feed tray is raised and PS315 turns ON, M302 turns backward after a predefined interval to start original feed operation. Then, when PS306 (original registration detection) detects the leading edge of the original and turns ON, M302 switches to high speed forward after a predefined interval to complete the original feed operation. After completing original feed at high speed forward, M302 returns to low speed forward and stops and goes into standby when PS308 (original conveyance detection) turns ON.

d. Original conveyance operation

When feeding the first original, M302 transports the original to the conveyance roller by continuing to rotate at high and low speed. During this time, M301 (original conveyance) starts rotating forward at low speed at predefined time after PS306 turns ON. The original reached to the conveyance roller is then conveyed to the scan position. After starting conveyance of the first original, M301 continues to rotate forward at low speed until the last original is scanned.

e. Scan operation

The original is passed over the slit glass of the optics unit by the low speed forward rotation of M301 and read (scanned). While the original is being scanned, original feed and conveyance operations continue, triggered by the turning ON of PS308.

f. Original mis-centering detection control

PS311 (original skew detection 1) and PS312 (original skew detection 2) are provided to detect the inclined leading edge of the original during conveyance. PS311 and PS312 are placed at the front and back of the pre-scan conveyance path and determine the inclination of the original by measuring the difference in interval at which the leading edge of the original turns these switches ON. A skewed image caused by original inclination is corrected through image processing so that the

image on the original is copied to a copy paper as it is on the original.

g. SDF (Single Document Feeder) control

When SDF mode is selected, SD304 (SDF switching SD) cut the drive force to the double feed prevention roller to facilitate original feeding.

MAIN BODY

In two side copy mode, an original that has been scanned on the front side is conveyed to the original reversal section to be reversed and then rescanned. At entrance to the original reversal section, there is a flapper to switch the original conveyance path. The flapper is driven by SD301 (flapper drive). The reversal roller, which reverses and conveys front-side-scanned original to the original reversal section and feeds that original to the scan section again, is driven by M304 (original exit 1). The original reversal roller which conveys original to the original reversal section is driven by M305 (original exit 2). When reversing and feeding large originals, the pressure roller is released by SD302 (pressure roller release). M304, M305, SD301, and SD302 are controlled by DFCB (RADF control board).

MS) is OFF or when there is original inside the RADF.

b. Original conveyance path switching/reversal

and original feed operation

(1) Small size original

SD301 is always OFF and the flapper is closed. Therefore, the scanned original, whether it is single side or double side, is conveyed to the reversal section by M304 rotating at low speed forward. When copying the back side of a double-side original, at predefined interval after PS309 (original reversal detection) detects the trailing edge of original and turns OFF, M304 rotates backward at low speed and then at high speed to reverse and feed the original. The reversed original is conveyed through the flapper and the guides to the conveyance roller.

RADF

1. Operation

a. Sensor activation during power ON

When SW1 (main) is turned ON, a sensitivity adjustment for PS309 (original reversal detection) and PS313 (original exit reverse detection) are performed. However, automatic adjustment is not performed when the RADF jam access cover is opened and MS301 (cover open/close

2-7

EDH-5

RADF

(2) Large size original

The scanned-single side original is conveyed to the original exit tray (large) by the original conveyance roller since SD301 is ON and the flapper is opened. In the case of large double-side original, the original is conveyed to the reversal section when SD301 turns OFF after scanning the front side of a double-side original . The original reaching the reversal section does not fit in the reversal section so it is fed to the large-size original exit tray side by the large original reversal roller, which is driven by M305 (original exit 2). During this time, SD303 (original exit gate) turns ON and the original exit gate is closed. The original conveyed to the reversal section is reversed and fed to the scan section again in the same manner as small originals. Since the original reaching the conveyance roller does not exit the reversal roller, SD302 is turned ON at predefined interval after high speed backward rotation of M304 to release the pressure roller for the reversal roller. This enables original conveyance using the conveyance roller. SD302 turns OFF when it detects an image scan complete signal from the main unit.

c. Two side original next original feed operation

(1) Small size original

During front-side scanning of two-side original, the original feed of the next one is started by the rotation of M302 (original feed) when PS306 (original registration detection) detects the trailing edge of the previous original and turns OFF. The next original stops and waits in standby at predefined interval after the turning ON of PS306 by its own leading edge. When the back side of the first original is scanned and PS308 (original conveyance detection) turns ON, M302 turns ON after a predefined interval to resume original feed to scan the front side of the next original. Thereafter, the same operation is repeated.

(2) Large size original

During front-side scanning of double-side original, the original feed of the next original is started when PS306 (original registration detection) detects the trailing edge of the previous original and turns OFF. The next original stops and waits in standby at predefined interval after the turning ON of PS306 by its own leading edge.

During ejection of previous original by reverse and exit operation, when PS309 (original reversal detection) detects the trailing edge of the previous original and turns OFF, M302 turns ON after a predefined interval to resume original feeding to scan the front side of the next original. Thereafter, the same operation is repeated.

The ejection destination of the original that has been scanned depends on the size of original. The original exit roller 1 which conveys the original to the original exit tray (large) is driven by M304 (original exit 1). The original exit roller 2 which conveys the original to the original exit section (small) is driven by M305 (original exit 2). The flapper which switches the original exit path and the original exit gate are driven by SD301 (flapper drive) and SD303 (original exit gate) respectively. M304, M305, SD301, and SD303 are controlled by DFCB (RADF control board).

1. Operation

a. Small size original exit operation

(1) Single-side original

Scanned original is conveyed to the reversal section since SD301 is OFF and the flapper is closed. Original conveyed to the reversal section is conveyed to the original exit gate by the reversal roller which is driven by M304. During this time, M304 drives the conveyance roller with low speed forward rotation. The original is conveyed to the original exit roller 2 since SD303 is OFF and the original exit gate is opened. M305 drives the original exit roller 2 with low speed forward rotation and ejects the

original to the original exit section (small) with the original surface facing down.

(2) Two-side original

A original that has been scanned on the back side is conveyed to the original exit gate in the same manner as single-side original. During this time, SD303 is ON and the original exit gate is closed. Therefore, the original is passed through the original exit reversal roller, which is driven by the low speed forward rotation of M305, and conveyed to the original exit reversal section. M305 turns OFF when PS313 ( original exit reverse detection) is turned OFF by the conveyed original. When SD303 turns OFF and the original exit gate opens, M305 starts high speed backward rotation after a predefined interval and reverses the direction of the conveyed original. Since the original exit gate is opened, the original is conveyed to the original exit section (small) rather than returning to the reversal section. As a result, the two-side original is ejected with the front side facing down.

b. Large size original ejection operation

(1) Single-side original

The scanned original is conveyed to the original exit roller 1 by the conveyance roller since SD301 is ON and the flapper is opened. The original exit roller 1 is driven by the low speed forward rotation of M304 and the original is ejected to the original exit tray (large) with the copy surface facing down.

(2) Two-side original

The original that has been scanned on the back side is conveyed to the reversal section since SD301 is OFF and the flapper is closed. When PS309 (original reversal detection) detects the trailing edge of conveyed original, SD301 (flapper drive SD) is turned ON and the flapper is opened. Then, M304 (original exit 1) rotates backward and the original is ejected to the original exit tray (large size original) since the flapper is open.

MAIN BODY

The size of the original placed in the original feed tray is detected by PS302 (original size detection

1), PS303 (original size detection 2), and VR301 (original size detection). PS302, PS303, and VR301 are controlled by DFCB (RADF control board) through PTBD (tray drive board). DFCB contains a non-volatile memory for storing data such as timing data and original size detection threshold.

1. Operation

a. Normal copy mode

DFCB detects the original size from the combination of the following signals:

(1) Drum axis direction size detection

A guide plate is connected to VR301 and the resistance vary with the position of the guide plate. This is used to determined the vertical dimension of the original.

(2) Original feed direction size detection

The horizontal dimension of the original is detected with the ON/OFF combination of PS302 and PS303.

(3) Original feed direction size detection

When the original is fed, M301 (original conveyance) turns forward and conveys the original to the original exit tray (large). M301 continues to rotate forward until PS306 detects the trailing edge of the original and turns OFF. At this point, the ON interval of PS306 is used to detect the size of original in the feed direction.

1. Registration roller

2. PS 306 (Originalregistration detection)

3. Original conveyance roller

4. PS308 (Original conveyance detection)

After a predefined interval since PS306 turns OFF, M301 changes direction and returns the leading edge of the original conveyed to the original exit section to the scan wait position. The trailing edge of the returned original is conveyed to the original exit tray (large) due to the shape of the conveyance guide plate. The backward rotation of M301 stops at predefined interval after PS308 (original conveyance detection) detects the leading edge of the original and turns OFF.

MAIN BODY

When the top cover opens or closes, M100 (LT up/down motor) rotates forward or backward to move the up/down plate up or down. The up/ down plate descends by 120 mm each time SW100 (LT tray down drive) is pressed while the top cover is opened. The related signals are PS100 (LT top cover open/close detection), PS101 (LT lower limit detection), and PS109 (LT upper limit detection).

1. Operation

a. Up/down plate descend timing

(1) ON timing

When the top cover is opened and PS100 (LT top cover open/close detection) is turned OFF, M100 rotates backward to lower the up/down plate. When SW100 (LT tray down drive) turns ON by pressing, M100 rotates backward to move the up/down plate down.

(2) OFF timing

M100 turns OFF at predefined interval after PS100 turns OFF or SW100 turns ON. This in turn lowers the up/down plate by 120 mm.

Paper Conveyance

Paper conveyance is carried out by conveyance

rollers (A), (B), (C), and (D); the intermediate

conveyance roller; the conveyance slide shaft;

and sub-tray paper exit rollers (A), (B), and (C).

These components are driven by the FNS con-

veyance motor (M1) by means of a timing belt.

Stacking is implemented by the stacker entrance

roller and the swivel roller. These rollers are

driven by the stacker entrance motor (M13) by

means of a timing belt.

Ejection to the main tray (following staple pro-

cessing) is implemented by the stacker paper

exit belt arm and the paper exit roller. These com-

ponents are driven by the paper exit motor (M7).

Ejection to the booklet tray is implemented by the

folding conveyance roller, the folding convey-

ance belt, the folding knife, folding rollers A and

B, and pressure rollers A and B. The folding knife

is driven by the folding knife motor (M19). The

conveyance belt, folding rollers, and pressure

rollers are driven by the folding conveyance

motor (M20) by means of a timing belt.

pling))

Sheets conveyed into the stacker are aligned by the oscillation of the (front and rear) alignment plates/upper. The alignment plates/upper are driven by the alignment plate/upper motor (M5).

b. Paper Alignment (Booklet Mode (FN-7 only))

Sheets conveyed into the stacker are aligned by the movement of the (front and rear) alignment plates/upper and the (front and rear) alignment plates/lower. The alignment plates/upper are driven by the alignment plate motor/upper (M5); the alignment plates/lower are driven by the alignment plate motor/lower (M15). The staplingand-folding stopper is moved by the staplingand-folding stopper motor (M14) and is released by the stapling-and-folding stopper release motor (M17).

c. Paper Exiting to the main tray

Stapled paper is sent to the paper exit by the paper exit arm. The paper exit belt is driven by the paper exit-roller motor (M7).

d. Feeding to the Folding Unit (FN-7 only)

The stapling-and-folding stopper release motor (M17) releases the stapling-and-folding stopper and feeds the paper into the folding unit.

*5 Paper Exit Opening Unit

Because the rotational speed of the paper exit roller is slower than that of the conveyance roller, the nip is in the released position except during the paper exit action. When a sheet of paper reaches the paper exit opening, the paper exit opening solenoid (SD704) activates the nip roller. The roller nips the sheet to deliver to the main tray.

2. Paper exit opening

3. Paper exit opening solenoid (SD4)

4. Paper exit opening motor (M8)

a. Staple Mode and Booklet Mode Operation for

Paper Sizes A4R and Above

Because paper of this size juts out from the stacker, the paper exit opening is held open from the start of copying until the completion of stapling.

b. Paper Exit of the Staple Mode (Flat Stapling)

Upon completion of stapling, the paperr exit closes, and the paper is grasped and ejected to the main tray. The opening and closing of the paper exit is controlled by the paper exit opening motor (M8).

c. Pressure of the Paper Exit Roller

The paper exit roller turns more slowly than the conveyance rollers (A, B, C, and D), and remains unengaged by the nip roller except during ejection. When paper reaches the paper exit opening, the paper exit roller is engaged by the nip roller and the paper is ejected to the main tray. Engagement and release is controlled by the paper exit opening solenoid (SD4).

Exit paper is conveyed to the sub-tray via the sub-tray paper exit rollers (A), (B) and (C) during the sub-tray mode. In this mode, the deceleration roller lowers when the sub-tray deceleration solenoid (SD6) turns ON; then the paper is nipped between the sub-tray deceleration solenoid and the sub-tray paper exit roller (C) rotating at a low speed, and the conveyance speed of the exiting paper decelerates.

*7 Folding by the Folding Unit (FN-7 only)

Paper is conveyed to the folding stopper by the action of the folding conveyance roller and the folding conveyance belts, and is then folded by the action of the folding knife and the folding rollers. The folding conveyance roller, the folding conveyance belts, the folding rollers, and the pressure roller are driven by the folding conveyance motor (M20). The folding stopper motor (M18) drives the folding stopper. The folding knife motor (M19) drives the folding knife.

FNS CB

M1 (FNS conveyance) drives paper conveyance (if main-tray exit) and paper exit (if sub-tray exit) by means of conveyance rollers (A), (B), (C), (D), conveyance slide shaft and the sub-tray paper paper exit roller (A), (B), (C). M1 is controlled by the FNS CB (FNS control board).

1. Operation

a. Interlock control

FNS paper-conveyance drive control is initiated by the ON signal from the main body START button. If MS1 (interlock) is OFF at this time, however, the finisher transmits an error signal to the main body CB and does not begin control.

b. PS207 (paper exit cover open/close detec-

tion) control

As mentioned above, FNS paper-conveyance drive control is initiated by the ON signal from the main body START button. But if PS207 (paper exit cover open/close detector) is [H] at this time (paper exit cover is open), the FNS transmits an error signal to the main body CB and does not begin control.

c. M1 (FNS conveyance) control

(1) Main tray paper exit operation

M1 is set ON by the ON signal of the START button and goes OFF a preset time interval after PS4 (FIN entrance passage) detects the trailing edge of the final copy paper.

(2) Sub-tray paper exit operation

SD6 (sub-tray deceleration) turns ON a predefined time after PS4 detects the trailing edge of the paper, and the deceleration roller is stuck

with pressure to the sub-tray exit roller (C). Thus the speed of ejecting paper is reduced. SD6 then turns OFF a predefined time after PS1 (sub-tray paper exit) detects the trailing edge of the paper.

8. M13 (Stacker entrance)

a. Conveyance to the stacker (sizes other than

A4 or B5)

(1) M13 (stacker entrance) ON timing

M13 is turned ON by the START button ON signal, and begins with high speed rotation. M13 then switches to low speed rotation a preset time period after PS5 (stacker conveyance passage) detects the trailing edge of the paper. M13 then returns to high speed rotation a preset period after PS5 detects the trailing edge of the paper. This action is repeated as necessary to transport all papers to be stacked into the stacker.

(2) M13 OFF timing

M13 goes OFF a preset time period after PS5 detects the trailing edge of the final paper set.

b. Conveyance to the stacker (A4 and B5 sizes)

(1) First set

Paper for the first set to be stapled is conveyed in the same way as other paper sizes.

(2) First paper of second and subsequent sets

M13 turns OFF a preset time period after PS4 (FNS entrance passage) detects the trailing edge of the first paper for the second or subsequent set, and the paper moves into the by-pass.

This prevents paper from moving into the stacker while stapling of the previous set is still in progress.

(3) Second and subsequent papers of second and

subsequent sets M13 resumes low speed rotation a preset time period after PS4 detects the trailing edge of the second paper of the set. This causes the first and second papers to move together (one atop the other) into the stacker. M13 switches to rapid rotation a preset time period after PS5 detects the trailing edge of the first and second papers, so that it is ready to handle the third paper of the set when it arrives from the main body. Third and subsequent papers for the set are then conveyed in the same way as the papers in the first set.

c. Paper alignment (trailing-edge alignment)

For operation in staple mode: The swivel roller adjusts the position of each paper (one paper at a time) within the stacker. For operation in booklet mode (FN-7 only): The stapling & folding stopper is moved and set into appropriate position. The swivel roller adjusts the position of each paper (one paper at a time).

When running in Sort or Group mode, the FNS carries out shifting of paper. Shifting is driven by M2 (roller shift), which is controlled by the FNS CB (FNS control board).

1. Operation

If operation is in sort or group mode, M2 (roller shift) turns ON a predetermined time period after PS4 (FNS entrance passage) detects the trailing edge of a paper that needs to be shifted. Rotation of M2 starts shifting of the conveyance slide shaft, while rotation of M1 (FNS conveyance) causes the shaft to turn, so that shifting and conveyance occur simultaneously. PS18 (roller-shift HP) turns ON when the conveyance slide shaft has been fully shifted, causing M2 to turn OFF. A specified time period after PS4 turns OFF, M2 turns ON and returns the conveyance slide shaft to its original position. PS18 turns OFF when the conveyance slide shaft has returned all the way, causing M2 to turn OFF again. This operation is repeated as necessary to shift paper as it moves toward the exit roller.

Return of the staple paper-end stopper to home position resets the flat-stapling stopper.

*3 Stapling Operation a. FN-115

The stapler motor/F (M24) and stapler motor/R (M22) in the stapler (F and R) run to inject a staple in order to bend it into the shape of the clincher. Rotation control of the motors M24 and M22 are exerted by the stapler HP PS/F (PS34) and stapler HP PS/R (PS31). The cartridge detection PS/F (PS36) and cartridge PS/R (PS39) detect presence and improper loading of a cartridge. Staple detection PS/F (PS37) and staple detection PS/R (PS40) detect presence of staples in the cartridge. After staples are charged, M24 and M22 run until the stapler ready PS/F (PS38) and stapler ready PS/R (PS41) are turned ON by staples, thus preventing blank stapling.
