MAIN BODY
M701 (FNS conveyance) operation is performed
by the 24V DC motor and controlled by the FNS
CB (FNS Control Board).
The related signals is PS704 (FNS Entrance).
1. Operation
a.
Interlock control
FNS paper conveyance drive control is initiated
by the ON signal from the main body's START
button. If MS701 (interlock) is OFF at this time,
however, the finisher transmits an error signal to
the main body's PRCB and does not begin this
control.
b. M701 (FNS conveyance) control
When the position of the START button is ON,
and the paper exit speed is high, ON from PS37
(main body paper exit) sets the speed to low, and
ON from PS704 (FNS entrance) sets the speed
to high after a predefined time period. For the
main tray paper exit operation, PS704 detects
the end of the paper, and, after a predefined time
period, the speed mode switches to medium to
match the paper exit speed of the FNS. Then,
after a predefined time, the mode returns to the
high speed to prepare for the next conveyance of
paper.

2. Signals
a.
Input signals
(1) SRXD (Main body to FNS CB)
Serial data line; transmits the operating status of
the main body's CB to the FNS CB.
(2) SCTS (Main body to FNS CB)
Acknowledgment signal, sent from the main
body to the FNS, allowing the FNS to send data
to the main body.
(3) 24V-IN (MS701 to FNS CB)
Interlock signal:
[H]: Front cover is closed.
[L]: Front cover is open.
(4) PS704 IN (PS704 to FNS CB)
Signal indicating whether the paper passes
through the entrance. The front and rear ends of
the paper are detected.
[H]: Paper does not exists.
[L]: Paper exist.
b. Output signals
(1) SRTS (FNS CB to Main body)
Acknowledgment signal, sent from the FNS to
the main body, allowing the main body to send
data to the FNS.
(2) STXD (FNS CB to Main body)
Serial data line; transmits the operating status of
the FNS to the main body's CB.
(3) M701 DRV A, A(FNS CB to M701)
Pulse signal to drive/control the Phase A of M701
(4) M701 DRV B, B(FNS CB to M701)
Pulse signal to drive/control the Phase B of M701
