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.
A666-6
10 January 1997DETAILED DESCRIPTIO NS
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.

[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.

[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.

2.5 FEED OUT MECHANISM
[C]
[B]
[A]
[D]
A666D505.wmf
After the copies have been stapled, the feed-out motor [A] turns on to drive
the feed out belt. The stack stopper [B] on the feed-out belt transports the set
of stapled copies up,(its speed is 450 mm/s) and feeds it towards the shift
tray. Approximately 500 ms after the feed-out motor turns on, it stops for 500
ms. At this moment, the exit roller [C] catches the stapled copies to feed them
out to the shift tray. Then, the feed-out motor turns on again until the stack
stopper actuates the feed-out belt home position sensor [D].
The transport motor drives the brush roller and the exit roller [C] (speed 500
mm/s). The transport motor turns on when the feed-out motor turns on at the
start of feed-out to drive brush roller. This prevents the brush roller from
disturbing the smooth upward passage of the leading edge of the copy set at
the start of paper feed. After 200 ms, the transport motor turns off and on
again in reverse to feed out the set of staple copies.

[F]
[E]
[G]

[A]

[C]
[D]
A666D506.wmf
The shift tray lift motor [A] controls the vertical position of the shift tray [B]
through the gears [C,D]. When the main switch is turned on, the tray is
initialized at the upper position. The trays upper position is detected when the
shift tray pushes up actuator feeler[E] until the actuator turns on the stack
height sensor [F]. Then the shift tray lift motor turns in reverse until the stack
height sensor turns off.
During copying, the actuator feeler [E] gradually rises as the copy stack
grows. When the stack height sensor [F] turns on, the shift tray lift motor
lowers the shift tray [B] until the sensor is off.
When the actuator [G] turns off the lower limit sensor [H], copying stops. After
copying ends and machine is stopped and the copies are removed, the shift
tray rises until the stack height sensor [F] is on. Then the shift tray lift motor
turns in reverse until the stack height sensor turns off.

[E]
[C]
[A]
[F]
[B]
[D]
[B][F]
A666D507.wmf
The horizontal position of the shift tray is controlled by the shift motor [A] and
the shift motor disk [B]. After one set of originals is copied and delivered to
the shift tray [C], the shift motor turns on, driving the shift motor disk and the
lever [D]. The shift tray base plate [E] is positioned by the lever, creating the
side-to-side movement required to stagger the copies.
When the shift motor disk [B]has rotated 180 degrees (when the shift tray is
fully shifted across), the cut-out in the shift motor disk turns on the shift
position sensor [F] and the shift motor [A] stops. The next set of copies is
then delivered. The motor turns on, repeating the same process and moving
the tray back to the previous position.
