[4] M712 (gate drive) Control
MAIN BODY
M712 (gate drive) performs the paper convey-
ance path switching between the sub-tray, main
tray or stacker section. The FNS CB (FNS con-
trol board) controls the operation of M712.
The related signal is PS716 (gate HP).
1. Operation
M712 (gate drive) is activated by the FNS oper-
ation signal from the main body, selecting one of
the three positions depending on the paper exit
destinations: the sub-tray (home position), main
tray or stacker. However, when the current paper
exit destination is the sub-tray, M712 is not acti-
vated (it is already in the home position).
After the operation, M712 returns to its home
position based on PS716 (gate HP).

[5] SD705 (by-pass gate) Control
MAIN BODY
SD705 (by-pass gate) only operates for small
size papers (A4, B5 or 8.5 x 11). The FNS CB
(FNS control board) controls SD705.
The related signal is PS704 (FNS entrance).
1. Operation
(1) First set:
While the sheets of the first set are being pro-
cessed, SD705 (by-pass gate) does not operate.
(2) Second set:
The stapling operation for the first set is acti-
vated, and, after a predefined time, SD705 (by-
pass gate) is activated to pull the first sheet of the
second set toward the by-pass.
SD705 stops it operation when a predefined time
has elapsed since PS704 (FNS entrance)
detected the rear end of the first sheet of the sec-
ond set.
SD705 does not operate when the second and
subsequent sheets of the second set are pro-
cessed.
(3) Third and subsequent sets:
PS704 (FNS entrance) detects the rear end of
the last sheet of the second set. Then, after a
predefined time, SD705 (by-pass gate) is acti-
vated to pull the first sheet of the third set toward
the by-pass.
SD705 stops it operation when a predefined time
has elapsed since PS704 (FNS entrance)
detected the rear end of the first sheet of the third
set.
SD705 does not operate when the second and
subsequent sheets of the third and subsequent
sets are processed.
