2. Explanation of each section

The 3-tray finisher consists of (1)an upper paper transfer 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.

5) Trays 1 (10) and 2 (7) paper discharge operation

When paper is delivered to the trays 1 (10) and 2 (7) at a high-speed in the 3 tray finisher, the trays 1 and 2 deceleration clutch (13) is operated at paper delivery timing to decelerate the paper discharge rollers 1 and 2 in order to align the paper to the trays 1 (10) and 2 (7) with high accuracy.

6) 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.

A. Upper paper transfer section

1) Paper transfer

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

The transfer speed is switched over between the copier speed mode and the high-speed mode according to the paper discharge mode and paper size.

2) Paper entry gate (4)

The paper entry gate (4) is operated by the paper entry solenoid(INGSL) to select the upper transfer (outside route) and reversion/short path according to the mode.

3) 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 (10) and transport to the tray 2 (7)/staple tray.

4) Paper discharge gate 2 (8)

The paper discharge gate 2 (8) is operated by the paper discharge gate 2 solenoid (OG2SL) to select between the routes for paper discharge to the tray 2 (7) and transport to the staple tray.

B. Reversion unit

1) Reversion motor (RVM)

The reversion motor is connected to the reversion roller (4). The paper is pulled into the reversion path by the reversion motor

rotating in forward, and fed into the upper transfer route by the motor rotating in reverse. When the paper is discharged through the shortpath, its transfer is performed by the reversion roller (4) until the paper enters the staple tray.

2) Reversion pressure release roller

The reversion pressure release roller (3) is pressure released or pressurized through ON/OFF control of the reversion roller pressure release solenoid, to achieve the reversion of the paper at a high speed without reducing JOB efficiency.

(1st sheet is reversed and discharged.)

(1)

5) Short path switching gate (1)

The short path switching gate (1) is operated by the short path switching solenoid (SPSL), to select the short path to feed paper to the reversion path and stable tray.

6) 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.

7) 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.

8) Tray 3 deceleration clutch (8) Tray 3 paper exit roller clutch (2)

The paper discharge rollers 3 and 4 are speed changed to improve the stackability of stapled paper being discharged to the off-set tray.

C. 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 sidewise edge of the paper.

2) Puddler (11)

The puddler clutch (PDCL) is turned ON when the paper is fed into the staple tray, to give the puddler 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.

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

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.

5) After the job, the stapler unit is returned to the home position.

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 sidewise 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 braked to a stop by the off-set home position sensor (2) turning ON.

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.

3) Upper limit sensor solenoid (T3UPSL)

When the paper is discharged from the off-set tray, the upper limit sensor solenoid is turned on to pull in the actuator so that the sheet discharged does not ride on the actuator of the upper limit sensor (7).
