MX-FN17  OPERATIONAL DESCRIPTIONS  6 – 13

2)

After transporting paper by a certain amount, the paper align-
ment motor F (FPAM_F) and the paper alignment motor R
(FPAM_R) are driven to shift the alignment plate to the home
position.

3)

After the paper rear edge passes the staple tray paper detec-
tor (FSTPD), the paper level detector solenoid (FPLDS) is
turned OFF and the bundle exit roller speed is decelerated at
the same time to decelerate paper exit of the paper bundle. At
the same time, the delivery roller lift motor (FDRLM) is driven
in the lifting direction to decrease the pressure of the bundle
roller. In addition, the tray lift motor (FTLM) is driven to lower
the load tray by 5mm.

4)

Immediately after the paper rear edge passes the bundle exit
roller, the paddle solenoid (FPS) is turned ON to scrape roller
falling onto the tray.

5)

When the paddle rotates one turn, the paper delivery motor
(FPDM) is stopped.

6)

After the paddle rotates one turn, the paper level detector sole-
noid (FPLDS) is turned ON for 100msec and then OFF. Then it
is turned ON after 400msec. At that time, if the paper surface
level is lower than the reference level, the tray lift motor
(FTLM) is driven to lift the load tray to the reference level.

7)

If there is next paper, the operation is repeated from "A-1)."

8)

If there is no next paper, the actuators are turned OFF and the
finisher operation status command is set to READY state, and
the transport operation is terminated.

When the operation mode command is received from the copier,
the finisher makes the finisher operation status command the JOB
and starts the transport operation.

1)

The paper transport motor (FPTM) is driven at the machine
paper discharge speed to receive paper discharged from the
machine. When the paper length is 216mm or less, the second
and later sheets in the same bundle are discharged from the
machine at the high speed. When the paper length exceeds
216mm, the sheets are discharges at the same speed as the
process speed.

1)

When the paper rear edge passes the paper rear edge sensor,
the paper transport motor (FPTM) is stopped and paper trans-
port is stopped.

2)

When the paper is stopped, the punch motor (FPM) is driven to
punch at the paper rear edge.

1)

After completion of punching, the paper transport motor
(FPTM) and the paper delivery motor (FPDM) are driven to
transport paper and the specified after-process is executed.
The motor speed is 480mm/sec.
