Section II Operation

2.1 Outline

This finisher receives commands from the copier and discharges into the tray the

papers sent from the copier in normal mode, shift mode or staple mode.

If the command to discharge into interruption copy bin is sent from the copier, it will

operate accordingly.

There are four paper exit modes.

2.1.3Exit route

There are three normal exit routes. The route that is used depends on the paper size and discharge mode.

(1)Route for small size

When small size paper is loaded normally, the paper passes under the buffer roller.

Buffer roller

Paper exit roller

Fig. 2-09

(2)Route for large size

When large size paper is loaded or the paper is loaded in R direction, the paper passes above the buffer roller.

This has an effect of expanding the distance between papers.

(3)Buffer route

Paper takes this route when small size paper is used in the job offset or staple mode.

Offset paper or the first and the second sheet of paper which follows the final paper to be stapled takes this route.

a) The first sheet of paper is transported toward the buffer roller.

2.2 Mechanism

2.2.1Job offset

The job offset operation, the first or last copy of each job is shifted forward, and the other copies of that job are exited in the normal position.

Papers are moved by the tamper.

Tamper home position detecting sensor (PI6) checks whether or not the tamper is on the home position.

When the switch is turned on, the finisher controller P.C.B. drives the tamper motor to return the tamper to the home position.

Finisher controller P.C.B. stops paper exit motor (M3) at the moment the rear end of the paper comes out of the transport roller 2.

Then the finisher controller P.C.B. reverses the rotation of paper exit motor, and the paper exit motor gear is shifted to drive position.

In response, the drive of paper exit motor is transmitted to swing guide, pushing up the guide.

When the swing guide open detecting sensor (PI18) detects the swing guide, paper exit motor stops, and swing guide stays elevated.

When swing guide is shifted up, papers are transported to the staple tray by rollet belt attached to the transport roller.

Papers transported to the staple tray are detected by staple tray paper detecting sensor (PI4).

The finisher controller P.C.B. drives tamper motor (M3) and adjusts the position of tamper to the point approximately 7mm from the rear end of the paper. When the paper is received by the staple tray, guide plate shunting solenoid (SL6) shunts the guide plate and places under the staple tray.

Then the tamper motor shifts papers forward by 30mm.

After shifting the paper, finisher controller P.C.B. reverses the rotation of tamper motor, and shifts the tamper to the position 7mm from the rear end of papers. Then the finisher controller P.C.B. reverses the rotation of paper exit motor again, and lowers swing guide.

When the swing guide is lowered and swing guide open/close detecting switch 2 (MS6) is turned on, paper exit motor rotates normally, causing normal rotation of the paper exit roller, and consequent discharge of papers into the tray.

After the paper is discharged, the guide plate returns to the elevated position.

2.2.2 Stapling

(1)Outline

Copies can be stapled by the stapler unit when staple mode is selected. The stapling position is decided by the selected staple mode and paper size. The stapler shifting/home-position sensor (PI7) detects whether or not the stapler unit is in the home position.

When the switch is turned on, the finisher driver P.C.B. drives the stapler shifting motor (M4) to return the stapler unit to the home position.

If the stapler unit is in the home position, it will stay there.

When the swing guide opens, the paper is transported by the rollet belt, (attached
to transport roller 2) to staple tray.
The paper is detected by the staple tray paper detecting sensor (PI4).
After the staple tray paper detecting sensor detects paper, the finisher controller
P.C.B. drives the tamper shifting motor (M3) to tap the paper.
The tamper is positioned 10mm from the end of paper.
The swing guide stays elevated until the last paper is loaded on the staple tray.

(3)The second and the proceeding papers

When the tail edge of the second and the proceeding paper roll out of transport roller 2, the finisher controller P.C.B. turns the paddle solenoid (SL5) on. Then the transport motor's (M1) drive rotates the paddle.

Papers pushed by the paddle are transported to staple tray.

Paddle operates twice for each B4, A3, LDR and LGL, and once for the other sizes.

When paper is loaded into the staple tray, the finisher controller drives the tamper shifting motor (M3) and taps the paper.

(5)Stapler unit shift control

The stapler unit is moved by the stapler shift motor (M4).

Home position is detected by the stapler shift/home position sensor (PI7). When the signal is sent from the copier, the stapler moves to the center of its shift range.

This movement occurs in every mode, because the selected mode is not yet been detected.

When the first sheet of paper reaches the registration sensor of the copier, the staple mode is signalled from the copier and the unit moves to the appropriate position depending on stapling point and paper size.

	When the staple movement home position detecting sensor is OFF, the finisher
	controller P.C.B. revolves staple motor in reversed direction until the sensor is
	turned ON, returning staple cam to the initial condition.
	The staples inside staple cartridge are detected by staple switch (MS9).
	Finisher controller P.C.B. drives staple motor (M6) only when swing guide close
	detecting switch 2 (MS6) is ON (swing guide is closed).
	This is to ensure safety in case fingers are put inside the stapler.

2.2.3 Tray Operation

(1)Outline

There are three paper exit trays used for normal feed.

Vertical movement of trays is carried out by the drive of the vertical shift motor (M5). Clock pulses from the tray vertical movement motor clock sensors 1 and 2 (PI19/PI9) detect the tray position after the home position detecting sensor (PI8) is activated.

Tray shift motor thermo switch (TP1) is attached to the tray vertical shift motor

(M5).

When the sensor temperature reaches approximately 73.5°C after continued movement of the motor, the sensor is turned ON and the finisher controller

P.C.B. shuts off the load to the motor.

When the sensor temperature cools down to approximately 40°C, the sensor is turned OFF and the finisher controller P.C.B. resumes, the loading on the motor.

When the power supply switch is turned on, the tray is returned to home position by the tray vertical shift motor (M5) which is driven by the finisher controller P.C.B.

When the tray is in home position, it will stay there.

The finisher controller P.C.B. moves the trays up and down to place the selected tray in the paper exit position.

The upper limit of the tray is detected by the tray upper limit detecting switch (MS5).

When the tray upper limit detecting switch is ON, the finisher controller P.C.B. stops the drive of the tray shift motor (M5).

The height of papers discharged into the tray is detected by height sensor (PS1). The sensor measures the distance between the upper half of the paper stack and the paper exit. If the distance becomes less the prescribed value, the tray is lowered.

When the safety area detecting switch (MS3) is turned ON while the shutter or swing guide is open, the finisher controller P.C.B. stops movement of finisher by shutting off the +24V power supplied to tray shift motor (M5).

(2)Shutter Operation

Before changing, by tray shift motor (M5) operation, the trays for receiving papers, the finisher controller P.C.B. closes the shutter on paper exit.

This prevents jamming of papers loaded on tray at paper exit.

The shutter moves upward (closes) when the transport motor 1 or 2 rotates in reverse, and stays in that position when the motor stops.

Next time the motor rotates in reverse, the shutter moves downward (opens, paper exit possible).

When the shutter stays in the elevated position, claws extended from the swing guide engage with the back face of shutter.

This prevents the swing guide from opening due to friction between loaded paper and swing guide at the time of tray shifting.

The claws are withdrawn and disengaged when the shutter is lowered. Upward movement of the shutter is detected by the shutter open sensor (PI5). Downward movement of the shutter is detected by the close detecting sensor (MS4).

The process is shown below:

a)Transport motor 1 or 2 rotates in reverse and the shutter moves upward.

(3) Detection of tray-loaded paper amount

	The amount of copies made in the sort mode (stapling or offset number) and
	discharged into tray, are memorized by the finisher controller P.C.B..
	The height of the paper stack is detected by the height sensor (PS1).
	The maximum loading amount in each tray is shown in table 2-01.
	When the tray is loading amount shown in table 2-01, the finisher controller						Operation
	P.C.B. stops operation and sends the signal to the copier that the tray is fully
	loaded.
