B. Paper alignment
1) When the rear edge of paper passes the paper pass roller, the
paper delivery motor (FPDM) is driven in the reversing direc-
tion 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. At the same time,
the delivery roller lift motor (FDRLM) is driven downward to
shift to the stand-by position of the paper delivery roller.
3) After the take-up roller is lifted, the paper alignment motor F
(FPAM-F) and the paper alignment motor R (FPAM-R) are
driven by a certain level to align paper to the front side or to the
rear side.
C. Paper delivery
1) After completion of alignment, the delivery roller lift motor
(FDRLM) is driven downward to lower the paper delivery roller
to the paper delivery position, discharging paper in the process
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
decelerated 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 paper deliv-
ery roller to the home position.

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.
When there is the next paper, repeat the procedures from "A-
2)". In the same bundle, however, the alignment direction of
the paper alignment plate is the same. When the bundle is
changed, the alignment position is changed to the opposite to
that of the previous bundle.
If there is no paper following, each actuator is turned OFF to
complete the transport operations.
unit
The paper delivery motor (FPDM) is driven in the paper deliv-
ery direction to lift the take-up roller. When a flapper solenoid
request (finisher paper pass) is received, the paper gate sole-
noid (FPGS) is turned ON to switch the paper pass gate to the
finisher side.
When paper enters the finisher, the paper transport motor
(FPTM) is driven at the machine paper delivery speed to
receive paper delivery from the machine.
When the rear edge of paper passes the paper delivery roller
of the machine, the paper transport motor (FPTM) is acceler-
ated to 400mm/sec. After a lapse of a certain time, the paper
alignment motor F (FPAM-F) and the paper alignment motor R
(FPAM-R) are driven to make the paper alignment plate stand
by outside of paper.
