SD706 (tri-folding gate) control
SD706 (tri-folding gate) operates the
tri-folding gate, which provides the
appropriate paper passage for either one of
the three operations: folding, stitch-and-fold,
or tri-folding.
The finisher CB (finisher control board)
controls the operation of SD706.
The related signal is PS725 (folding exit).
1 Operation
When the booklet stopper stops at the
tri-folding position, SD706 (tri-folding gate)
is activated. This operates the tri-folding
gate, providing the paper passage that
leads to the tri-folding stopper.
When PS725 (folding exit) has detected
the trailing edge of the paper and a
predefined time period has elapsed since
then, SD706 is deactivated.
