34 Finisher unit explanation ENWW
1 Operation
a Staple mode (for papers whose length
in the feeding direction is larger than
B5R)
The finisher operation signal from the
MFP 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 tri-folding
modes
The ON signal from the MFP's START
button lets M708 (paper exit opening)
rotate, causing the paper exit opening to
be opened.
When PS725 (folding paper exit) or
PS729 (folding 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. When PS712 (paper exit
opening HP) detects the position
closed, M708 stops.

M721 (upper-tray paper exit)
control
M721 (upper-tray paper exit), controlled by
the finisher CB (finisher control board),
drives the upper-tray paper exit roller.
The related signals are PS701 (upper-tray
paper exit), PS704 (finisher entrance), and
PS719 (upper-tray full).
1 Operation
a M721 (upper-tray paper exit) control
M721 (upper-tray paper exit) starts its
high-speed rotation when PS701
(upper-tray paper exit) detects the
leading edge of the paper.
When PS704 (finisher entrance) has
detected the trailing edge of the paper
and a predefined time period has
elapsed since then, the rotation of M721
changes to low.
When PS701 detects the trailing edge
of the paper and a predefined time
period has elapsed, M721 stops.
