2. DETAILED DESCRIPTIONS

2.1 JUNCTION GATE MECHANISM

[B]

[A]

[B]

[A]

A666D500.wmf

When the entrance sensor is activated in face-up mode, the junction gate
solenoid [A] turns on and the junction gate [B] is closed. Then, the paper is
transported directly to the shift tray and its maximum speed is 180 mm/s.

When the entrance sensor is activated in face-down or staple mode, the
junction gate solenoid [A] stays off and the junction gate [B] is open. Then the
paper is transported to the jogger unit.

2.2 PAPER REVERSING MECHANISM

[A]

A666D501.wmf

The paper is sent to the staple unit when face-down mode is selected. The
paper is transported to the staple unit at 180 mm/s until the trailing edge of
the paper turns off the copier exit sensor. After the exit sensor is turned off,
the paper transport speed is changed to 500 mm/s.

When the trailing edge of the paper passes through the inverter sensor [A],
the transport motor turns off. Then, the transport motor turns on in reverse
and the paper is transported to the shift tray.

2.3 JOGGER UNIT PAPER POSITIONING MECHANISM

[A]

[B]

A666D503.wmf

[C]

[D]

A666D502.wmf

In staple mode, each sheet of copy paper is vertically and horizontally
aligned when it arrives in the jogger unit.

For the horizontal alignment, the jogger motor [A] moves the front jogger
fence [B] to align the copies.

For the vertical alignment, the brush roller [C] pushes the trailing edge of the
paper against the stack stopper [D]. The position of the stack stopper
depends on the paper size (LT or A4), and is changed by the feed-out motor.

A666D508.wmf

[E] [H]

[F]

[I]

A666D504.wmf

The staple hammer [A] is driven by the stapler motor [B] via gears, a
eccentric cam [C].

When the aligned copies are brought to the stapling position by the brush
roller and jogger fence, the stapler motor [B] turns on. When the cam [C]
completes one rotation, the staple hammer home position sensor [D] turns
off, detecting the end of the stapling operation. The staple motor then turns
off.

The feed gear [E] drives staple feed roller [F] to feed a sheet of staples. The
feed gear is driven by the long hook [G] when the hammer moves up and by
the short hook [H] when the hammer moves down.

When there is only one sheet of staples left in the cartridge, the actuator [I]
moves up and the staple end sensor is activated.

When jammed staples are left in the staple unit, release and move up the
staple guide [J] to remove the jammed staples.
