[3] M719 (folding knife) Control

MAIN BODY
M719 (folding knife) drives the folding knife. This
knife is used when the mode is folding, stitch-
and-fold, or three-folding.
The FNS CB (FNS control board) controls the
operation of M719.
The related signals are PS722 (folding knife HP),
PS725 (folding paper exit), and PS726 (folding
passage).
1. Operation
PS726 (folding passage) detects the paper and
the booklet stopper stops at the folding position.
After a predefined time period has elapsed since
then, M719 (folding knife) is activated, letting the
folding knife protrude toward the paper.
The operation of PS726 ends when the folding
knife returns and the signal from PS722 (folding
knife HP) changes from H to L.
