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,

49
 2. Detailed Descriptions

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.

7 Shift roller

Shift eject mechanism

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.

50
 Internal Finisher SR3130 (D690)

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.

No. Description No. Description

1 Shift roller 3 Shift motor

2 Shift roller 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.

51
 2. Detailed Descriptions

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.
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

52
 Internal Finisher SR3130 (D690)

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

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.

No. Description No. Description

1 Stapler Home Position sensor 3 Stapler retreat motor

2 Stapler

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.

54
 Internal Finisher SR3130 (D690)

[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.
