3. Paper exit of a stapled bundle

In the case of A3, WL

a. When paper is discharged from t he machine, the finisher raises

the direction switch gate right to pass the paper to the alignment tray. When the read edge of paper passes the paper entry sensor, the operation is triggered. That is, when the rear edge of paper passes the direction switch gate right, the gate i s lowered to store the rear edge of paper completely in the alignment tray.

2. Operational descriptions

1. Paper exit to the top tray

When paper is discharged from the machine, the finisher lowers the direction switch gate right to pass the paper to the upper transport path (escape transport section) and lowers the direction switch gate left to discharge the paper to the top tray. The direction switch gate right is triggered by the finisher paper entry sensor and operated only when the paper lead edge passes through it.

2. Paper exit to the offset tray

When paper is discharged from the machine, the finisher lowers the direction switch gate right to pass the paper to the upper transport path, and lowers the direction switch gate left to discharge the paper to the offset tray. The direction switch gate right is triggered by the finisher paper entry sensor and operated only when the paper lead edge passes through it.

b. The rear edge plate and the side guide plate are moved in the

paper alignment direction to lower the upper alignment plate, performing alignment. After alignment, stapling is performed by the staple unit.

c. After alignment and stapling, the side guide plate is loosened and

the shutter is lowered to discharge paper to the paper exit roller by the rear edge plate. The bundle of paper is discharged to the offset tray by the paper exit roller.

· In the case of small size

a. The rear edge plate is moved to the center and the direction switch

gate right is raises to pass the paper to the alignment tray. When the read edge of paper passes the paper entry sensor, the operation is triggered. That is, when the rear edge of paper passes the direction switch gate right, the gate is lowered to store the rear edge of paper completely in the alignment tray.

b. When the second last paper is passed, the rear edge plate (1) is

lowered and passed under the paper bundle (2) to the rear edge of the paper bundle (3). Then the rear edge plate is raised. (HP position)

e. The rear edge plate and the side guide plate are moved in the

paper guiding direction and the upper guide plate is lowered to perform the last alignment. Then stapling is performed by the staple unit.

f. After alignment and stapling by the stapler unit, the side guide

plate is loosened and the shutter is lowered. The paper is moved to the paper exit roller by the rear edge plate, and discharged to the offset tray by the paper exit roller.

c. When the last paper from the machine passes the direction switch

gate right, it lowers the gate.

d. The paper bundle is moved in the paper exit direction by the rear

edge plate.

3. Descriptions on each section

This machine is composed of the paper exit unit and the alignment unit. The paper exit unit includes the paper exit tray 1 and 2. The paper exit tray 2 is provided with the offset function and the lift-up function.

The alignment unit includes the paper transport section used f or the non-staple mode, the paper alignment section for the staple mode, and the staple unit.

a. Paper exit unit section

(1) Paper transport (Main motor)

By rotating the main drive motor, the paper exit unit and the all transport rollers of the alignment unit are driven.

(2) Tray 1 full detection

The top of paper bundle on the tray is detected by t he combination of the lever and the photo sensor to judge paper full on Tray 1.

(3) Lift-up section

· Lift-up motor

In order to discharge paper always at a fixed posi tion regardl ess of paper load on the tray 2, the lift-up motor is driven, the pulley is rotated normally or in reverse, and the timing belt is driven to move the tray 2 up and down.

· Full detection

Paper full on the tray 2 is detected in combination between the lower limit sensor ON and detection of the top of paper bundle on the tray by the paper exit actuator.

(4) Offset tray section

· Offset motor

The offset motor moves the offset tray vertically to the paper exit direction so that each bundle of paper discharged to the offset tray is separately grouped.

· Paper exit clutch

This clutch is turned on when a stapled bundle of paper is discharged so that the bundle of paper is warped by the difference between the speeds of the upper and the lower paper exit rollers, preventing the bundle from being caught by the preceding bundle’s staple.

b. Alignment unit section

(1) Transport switch gate right (gate right solenoid)

Selection between the transport section and the alignment section in the alignment unit is made by the transport switch gate right. This gate drops the rear edge of paper entering the alignment section so that the rear edge is completely transported.

(2) Rear edge plate uni t

· Rear edge plate motor

The motor is turned on at the timing when paper enters the alignment tray to drive the rear edge plate unit. Paper of A3 or WLT is aligned to the shutter, and paper of a smaller size is aligned to the right side of the alignment tray in the transport direction.

· Rear edge plate solenoid

After provisional alignment of small size paper, this solenoid puts down the rear edge plate of the rear edge unit to pass it under the aligned paper. After returning to the home position, it is turned off and the rear edge plate is put back and paper is transported to the shutter.

(3) Side guide plate (Guide plate motor)

When paper enters the alignment tray, this plate is driven to align paper vertically to the paper transport direction toward the fixed wall of the alignment tray front side.

(4) Shutter (Shutter soleno id )

The shutter solenoid drives the shutter which stops the lead edge of paper for alignment. After stapling, the shutter is put down to transport paper to the paper exit roller.

(5) Transport switch gate left (Gate left solenoid)

Paper passed through the escape transport path is sent to the tray 1 or to the tray 2.

· Reciprocating operations in the above shift quantity are per-

formed. At the last page, the plate stops at a position about 2mm from the edge. ® Staple process

The last return is made by the pushing quantity (2).

· For provisonal alignment paper (B4 or less), the rear edge plate

passes under a bundle of paper to reach the home position, and stands by at a position slightly wider than the paper width (about 2mm) until the final alignment is performed toward the shutter. After completion of the final alignment, the plate stops at a position about 2mm from the edge similarly to the above, and stapling is performed.

5. Paper exit operation

· When a bundle of paper is discharged after stapling, the side

guide plate moves to a position so as not to interfere discharging and to prevent against skew feeding of the bundle.

Paper width 12pulse (about 2.3mm)

6. Next job

· The rear edge plate pushes paper by specified distance, and

returns to the home position. The above procedures are repeated for the next job.

· The pulse number is rounded at the first digit below the decimal

point.

4. Alignment operation

· A3, WLT

Reciprocating alignment operation in the above shift quantity is performed toward the shutter. At the last page, the plate stops at a position about 2mm from the edge. ® Stapling process

· B4 or less

Reciprocating alignment operation in the above shift quantity is performed toward the provisional alignment reference wall. After the last page is aligned, the rear edge is put down, and t he unit returns to the home position. After detection of the home position, the rear edge plate is raised and the bundle of paper is transported to the shutter. After completion of the final page alignment, the plate stops at the paper edge. ® Stapling process

5. Paper exit operation

The stapled bundle of paper is lifted up by the rear edge plate and pushed to the paper exit roller.

6. Next job

· The pushing distance of a paper bundle is a little bit greater than

the distance (71.6mm) between the shutter and the paper exit roller. After pushing, moves toward the home position without putting down the rear edge plate. The next job paper which is in stand-by in front of PS is fed, and the above procedures are repeated. If the operation is completed with one job, the paper bundle is
