2. Outline of the transport path
The outline of the transport path is described below.
3. Non-sort mode
When the operation mode command is received from the copier,
the finisher starts the transport operation.
the finisher starts the transport operation.
A. Reception of paper discharged from the main
unit
1)
The rear edge take-up roller solenoid (FARLS) is turned ON,
and the rear edge take-up roller is lifted.
and the rear edge take-up roller is lifted.
2)
The paper transport motor (FPTM) is driven at the same speed
as the paper delivery speed of the main unit to receive deliv-
ered paper from the main unit.
as the paper delivery speed of the main unit to receive deliv-
ered paper from the main unit.
3)
When the paper rear edge passes the delivery roller of the
main unit, the paper transport motor (FPTM) is accelerated to
500mm/sec. At the same time, the paper alignment motor F
(FPAM-F) and the paper alignment motor R (FPAM-R) are
driven to put the paper alignment plate in the standby mode
outside of the paper width. In addition, the rear edge take-up
roller solenoid (FARLS) is turned OFF to lower the rear edge
take-up roller.

B. Paper alignment
1)
After the paper rear edge passes the paper pass roller, the
paper delivery motor (FPDM) is driven in the alignment direc-
tion at 500mm/sec, and the take-up roller is rotated and low-
ered to take up the paper rear edge to the rear edge plate.

2)
When the paper rear edge detector F (FPRD-F) is turned ON,
the paper delivery motor (FPDM) is driven in the paper delivery
direction at 500mm/sec, and the take-up roller is lifted and the
paper delivery roller is rotated. At the same time, the delivery
roller lift motor (FDRLM) is driven downward to lower the paper
delivery roller to the standby position.
