      2. MECHANISM

Straight paper ejection mechanism

Paper ejected from the printer unit is transported by a transport roller and eject roller via an entrance roller. These are driven by entrance motor, transport motor and eject motor which permit linear speed correspondence. The paper exit driven roller stands by at a certain distance from the paper exit roller, and its descent/ascent is performed by an eject guide plate movable motor depending on the detection timing of the sensors (motor operates CW/CCW).

The paper eject open/close guide plate descent/ascent timings are as follows:

• Descent: Paper rear edge passes entrance sensor

• Ascent: Paper rear edge passes transport sensor

  The eject guide plate is provided with a Home Position sensor which detects the home position during ascent.

  Shift eject mechanism

  INTERNAL FINISHER SR3130 (D690)

  As with straight eject, shift eject is also done by transporting the paper to a transport roller and an eject roller via an entrance roller.

  In shift operation, a shift roller is moved from front to back during transport by the driver of a shift motor.

  Shift roller operation timings are as follows:

• Shift operation: Paper rear edge passes entrance sensor

• Return to original position: Paper rear edge passes transport sensor The shift roller detects the home position by a Home Position sensor.

  The shift roller motor operates CW/CCW, and shifts the paper from front to back. The home position is located at the back of the displacement range, and is detected by a Home Position sensor.

  Staple eject mechanism

  Staple eject requires that transported paper is temporarily stored in a staple tray. After rear edge detection of the transported paper is performed by a transport sensor, a positioning roller unit descends and transports it to a staple tray.

  

  
  

  

  
  

  

  Positioning roller ascent/descent mechanism

  The positioning roller unit is made to ascend/descend by a positioning roller up/down drive motor (the motor operates CW/CCW), and its position is detected by a Home Position sensor. The positioning roller rotates in the opposite direction to the transport roller, and has the function of transporting paper to the back of the staple tray.

  INTERNAL FINISHER SR3130 (D690)

  Paper rear edge alignment mechanism

  The rear edge of paper transported by the positioning roller is made to project against a rear trailing edge fence by a reverse roller. It rotates continuously until the bundle of paper is ejected after it is stapled.

  The reverse roller is driven from a transport roller via a gear, and is always situated above the stapler tray. A driven roller is installed on the side of the stapler tray which reduces wear of the reverse roller.

  Paper detection on stapler tray

  The stapler tray is provided with the following sensors which detect paper status in the tray.

  • Paper jam in tray: tray jam sensor

  • Paper present/absent in tray: paper sensor

    Jogger mechanism (paper alignment)

    Paper transported to the stapler tray is aligned one sheet at a time by a jogger fence. The jogger fences are driven forwards and backwards independently, and align the paper with the tray center. Jogger fence drives are installed at the front and back. Home Position sensors are also installed at the front and back.

    When the paper alignment is performed, the jogger fences move from the home position, and stand by 7 mm away from the paper to be stapled. When the paper is then transported to the tray, the jogger fence (rear) moves according to the paper size and aligns the paper. The jogger fence (rear) stands by 7 mm away from the paper, and again moves 7 mm towards the paper in order to perform paper alignment, so it moves a total of 14 mm. During the paper alignment, the jogger fence (rear) repeats this movement.

    Stapler movement mechanism

    INTERNAL FINISHER SR3130 (D690)

    Stapler specification is as follows:

  • There are three stapling positions, i.e., one front parallel, one back parallel and two parallel.

  • 30 large sheets or 50 small sheets can be stapled.

To change the stapling position, a mechanism is provided which moves the stapler. The stapler is moved by a stapler motor, and the home position is detected by a Home Position sensor.

The stapler moves from the home position to the paper size to be stapled, and temporarily stands by. Next, the paper is transported, and after the jogger operation (paper alignment), stapling is performed.

The following picture shows the stapler standby position according to various stapling positions. From the left, there is front parallel one position, back parallel one position, and parallel two positions.

For parallel two positions, the first staple is inserted from the front, and it then moves to the back to perform stapling.

Stapling is performed back and forth, i.e., the second staple is back > front, the third staple is front > back, etc.

[A]: Front parallel, one position [B]: Back parallel, one position [C]: Parallel, two position

Paper eject (bundle eject)

After stapling, the eject paper open/close guide plate descends, and ejects the bundle of paper while gripping it with the eject roller.

Paper press mechanism

For ejected paper, a paper press unit is provided to immobilize the paper above the tray. It is driven by a paper press drive motor (motor operates CW/CCW)

The paper press unit is provided with a paper surface sensor which detects the upper part of the paper, and a Home Position sensor which detects the home position of the paper press unit. The paper surface sensor detects the number of sheets in the tray, and if the number is large, it descends the tray to a suitable position.

Tray drive mechanism

The eject tray has a mechanism which descends the tray to a suitable position. This is driven by a tray drive motor (motor operates CW/CCW). It operates when the paper surface sensor cannot detect paper in the tray, and descends the eject tray until detection is performed.

Tray full detection mechanism

When the eject tray descends to its maximum, a full detect sensor below is covered by the eject tray filler, and it is detected that the top of the tray is full. During full tray detection, paper transport is temporarily stopped. After the paper bundle is released, the tray is raised to a suitable position, and the eject operation is repeated.
