[9] M708 (paper exit opening) Control

MAIN BODY
In the staple (when the length of the paper in the
feeding direction is larger than B5R), booklet, or
three-folding mode, M708 (paper exit opening)
drives the open/close operation of the paper exit
opening through the link mechanism.
The FNS CB (FNS control board) controls the
operation of M708.
The related signals are PS712 (paper exit open-
ing HP), PS725 (folding exit), and PS729 (folding
full PS).
1. Operation
a. Staple mode (for papers whose length in the
feeding direction is larger than B5R)
The FNS operation signal from the main body
lets M708 (paper exit opening) rotate, causing
the paper exit opening to be opened.
Upon completion of the stapling operation, M708
(paper exit opening) rotates again to start the
closing operation of the paper exit opening.
When PS712 (paper exit opening HP) detects
the closed position, M708 stops.
The steps above are repeated for each set of the
sheets that will be stapled.
b. Folding, stitch-and-fold, and three-folding
modes
The ON signal from the main body's START but-
ton lets M708 (paper exit opening) rotate, caus-
ing the paper exit opening to be opened.
When PS725 (folding paper exit) or PS729 (fold-
ing full PS) has detected the trailing edge of the
last sheet, and a predefined time period has
elapsed since then, M708 again rotates to start
the closing operation of the paper exit opening.
