[4] OPERATIONAL DESCRIPTIONS

1. Transport route

The 3-tray finisher’s transport routes are as follows. a) Tray 1 face-down paper discharge

c) Tray 3 outside turn face-down paper discharge

b) Tray 2 face-down paper discharge

2. Explanation of each section

The 3-tray finisher consists of (1) an upper paper transport section, (2) a reversion section, (3) a staple tray, (4) an offset tray, and (5) an elevator section.

It has the following functions: Paper discharge to a selected tray, paper reversion, stapling for paper delivered to the offset tray (3 positions), offset, and elevation. Each function is performed according to the mode instructed by the copier.

8/19/1999 4 – 1

AR-FN3

A. Upper paper transport section

1) Paper transport

By rotating the main driving motor (FM), the transport rollers in the finisher are driven.

2) Paper discharge gate 1 (1)

The paper discharge gate 1 (1) is operated by the paper discharge gate 1 solenoid (OG1SL), to select between the routes for paper discharge to the tray 1 (8) and transport to the tray 2 (5)/staple tray.

3) Paper discharge gate 2 (6)

The paper discharge gate 2 (6) is operated by the paper discharge gate 2 solenoid (OG2SL) to select between the routes for paper discharge to the tray 2 (5) and transport to the staple tray.

4) Trays 1 (8) and 2 (5) paper discharge operation

When paper is discharged to tray 1 (8) and tray 2 (5), tray 12 reduction clutch (11) is operated at the paper discharging timing to reduce the speed of paper discharge rollers 1 and 2, improving the accuracy of paper alignment in tray 1 (8) and tray 2 (5).

5) Trays 1 (10) and 2 (7) paper full detection

Whether the trays 1 (10) and 2 (7) are filled with paper is detected by the tray 1 and 2 paper full sensor.

B. Staple tray

1) Jogger motor (JGM)

The jogger motor is driven when the paper is fed into the staple tray, to operate the jog plates F and R so as to align the sideways edge of the paper.

2) Paddler (11)

The paddler clutch (PDCL) is turned ON when the paper is fed into the staple tray, to give the paddler a full turn so as to drop the paper downward (pusher), thus achieving alignment in the vertical direction.

3) Pusher motor (PSM)

With the pusher motor rotating, the paper stored inside the staple tray is lowered from the home position (discharge position) to the stapling position; after stapling, the paper inside the staple tray is elevated from the stapling position to the home position.

4) Staple unit movement motor (STUM)

The staple unit is moved to the stapling positions (front, far end, 2 centers) by the staple unit motor.

5) Staple tray paper discharge

When the paper delivery roller pressure release clutch (STORCL) is turned ON, the paper delivery pressure release roller (4) is pressurized through the cam to discharge the paper from the stable tray.

6) Paper discharge gate 3 (5)

The paper discharge gate 3 (5) is operated by the paper discharge gate 3 solenoid (OG3SL) to switch over the routes of paper inside the staple tray between the paper discharge side and the staple side of the off-set tray.

7) Tray 3 paper discharge motor

The tray paper discharge motor (12) is rotated to drive the paper discharge rollers 3 and 4 to discharge paper to the tray 3.

Jog plate F

Jogging in lateral direction

1) The jog plates are moved to the stand-by position before the paper is fed to the staple tray.

2) Immediately after the paper is fed into the staple tray, the jog plate is moved to the paper size position to ensure the alignment of the paper.

Stapler unit movement at the time of stapling (2-point stapling action is added.)

1) The pusher is elevated to the position which makes it possible for the staple unit to move.

2) The staple unit is moved to the staple position where the 2nd staple is driven.

3) The pusher (sheets to be stapled) is lowered to the stapling position.

4) Sheets are stapled.

5) The staple unit is returned to the 1st staple position. (After the job is finished, the staple unit is returned to the home position.)

D. Off-set tray

1) Off-set motor (3)

When the off-set motor (3) is driven, the tray is shifted sideways against the direction in which the sheets are delivered, so that the sheets discharged into the off-set tray (1) are sorted by the specified number of sheets. The rotation is unidirectional and controlled by the crank. The motor is stopped by the off-set home position sensor (2) turning ON.

3) The paper is stapled ... (in the case of 2-point stapling, the action that is described on the following page is added.)

4) The pusher (the sheets stapled) is elevated to the paper discharge position.

E. Elevator

1) Elevator motor (3)

When the elevator motor (3) is driven, the winding pulley (5) is rotated in both forward and reverse to wind up the wire (6) stretching vertically so that the tray 3 (off-set tray) is moved up and down. This allows the discharge of paper at a fixed position according to the number of sheets to be loaded on the off-set tray.

2) Off-set tray full and load detection

When the power is turned ON, the off-set tray lowers to the lower limit sensor (4) position. Then it elevates until the upper limit sensor (7) turns ON, while counting the encoder pulses of the elevator motor (3).

The volume of paper loaded on the off-set tray is calculated (0 100%) by counting the number of pulses from the elevator encoder (1).

The off-set tray is judged to be full when both the lower and upper limit sensors (4), (7) are turned ON.

ing to the simulation 3-6: Adjusting Finisher Jogger Position.

Sim. 3-6: Adjusting Finisher Jogger Position

The screen above is displayed after the sub number of the simulation is entered.

1) Adjust the value with the numeric keypad.

2) The joggers in the finisher are operated by pressing the [EXECUTE] key. The [EXECUTE] key is displayed in reverse video during loading operation. When the [EXECUTE] key in this state is pressed, loading operation can be canceled.

Condition Adjusting procedure

1 When the

deviation in the direction A) exceeds 1 mm.

Note: The width between joggers can be visually checked by observ-

ing the label inside the staple tray.

Decrease the simulation value. (Decreasing the simulation by 1 narrows the width between the joggers by 0.63 mm.)

Increase the simulation value. (Increasing the simulation value by 1 wi dens the w idth between the joggers by 0.63 mm)

The spacing between labels is 0.5 mm.
