ENWW Conveyance section 31
Finisher unit explanation
2 Signals
a Finisher CB input signals
1 PS718 IN (PS718 to finisher CB)
Signal relating to the shift position
[L] to [H]: Straight position
[H] to [L]: Shift position
b Finisher CB output signals
1 M702 DRV (finisher CB to M702)
Signal to drive/control M702.
[L]: M702 on
[H]: M702 off
M707 (paper exit roller) control
M707 (paper exit roller) drives the main tray
paper exit roller and the paper exit belt of the
stacker section.
The finisher CB (finisher control board)
controls M707.
The related signals are PS704 (finisher
entrance), PS706 (main tray paper exit),
PS709 (paper exit belt HP), and PS712
(paper exit opening HP).
1 Operation
a Straight, sort, and group modes
When PS704 (finisher entrance) detects
the leading edge of the paper, M707
starts to rotate at a high speed. When
PS704 has detected the trailing edge of
the paper and a predefined time period
has elapsed, the rotation of M707
changes to low. Then the paper delivery
action is performed.
When PS706 (main tray paper exit) has
detected the trailing edge of the paper
(preparation for the next paper
conveyance) and a predefined time
period has elapsed, the rotation speed
of M707 returns to high.
When PS704 has detected the last
paper and a predefined time period has
elapsed, M707 ceases to rotate.
b Staple mode (for papers whose length
in the feeding direction is smaller than
B5R)
The finisher operation signal from the
MFP lets M707 (paper exit roller) rotate.
When PS709 (paper exit belt HP) signal
has changed from off to on and a
predefined time period has elapsed,
M707 stops. The paper exit arm moves
to the staple mode HP.
When the stapling operation has been
completed, M707 rotates to drive the
paper exit belt of the stacker section.
This action allows the paper exit arm to
lift the paper to the level of the paper
exit roller, which delivers it to the main
tray.
When PS709 detects the change in
signal, from off to on, M707 stops.
