MX-FN13  OPERATIONAL DESCRIPTIONS  6 – 3

1)

When the rear edge of paper passes the paper pass roller, the
paper delivery motor (FPDM) is driven in the scraping direction
at 400mm/sec, descending and rotating the take-up roller to
pull the paper rear edge to the rear edge plate.

2)

After a lapse of time from detecting ON of the paper rear edge
detector (FPRD), the paper delivery motor (FPDM) is driven in
the paper delivery direction at 400mm/sec, lifting the take-up
roller and rotating the paper delivery roller.

3)

After a lapse of a certain time from detecting ON of the paper
rear edge detector (FPRD), the paper alignment motor F
(FPAM-F) or the paper alignment motor R (FPAM-R) is driven
by a certain level depending on the paper to be aligned to align
paper to the staple position.

4)

After completion of alignment, the alignment roller lift solenoid
(FARLS) is turned OFF to descend the rear edge take-up
roller. If two or more sheets of paper are aligned, the alignment
motor operated in procedure 3) to shift the paper alignment
plate to the home position. The operations from [A-2] are
repeated for the specified number of sheets. After completion
of alignment of the specified number of sheets, the staple
motor (FSM) is driven to perform stapling.

1)

After stapling, the paper alignment motor R (FPAM-R) and the
paper alignment motor F (FPAM-F) are driven to separate the
paper alignment plate 3mm away from paper. At the same
time, the delivery roller lift motor (FDRLM) is driven downward
by a certain level to shift the paper delivery roller to the paper
delivery position, discharging the paper bundle from the pro-
cess tray.

2)

After detecting OFF of the paper rear edge detector (FPRD),
the paddle solenoid (FPS) is turned ON to shift to the delivery
paddler to the save position.

3)

After a lapse of time from detecting OFF of the paper rear edge
detector (FPRD), the paper delivery motor (FPDM) is deceler-
ated to decelerate paper delivery. At the same time, the paper
alignment motor F (FPAM-F) and the paper alignment motor R
(FPAM-R) are driven to shift the paper alignment plate to the
home position.
The alignment roller lift solenoid (FARLS) is turned OFF to
descend the rear edge take-up roller.

4)

After the paper passes the paper delivery roller, the delivery
roller lift motor (FDRLM) is driven upward to lift the delivery
roller to the home position.

5)

After lifting the paper delivery roller, the paddle solenoid (FPS)
is turned OFF to rotate the paper delivery paddler one turn and
to press paper with the paper level actuator.

6)

When there is the next paper, repeat the procedures from "A-
2)".

7)

If there is no paper following, each actuator is turned OFF to
complete the transport operations.
