1 Operation
M712 (gate drive) is activated by the finisher
operation signal from the MFP, 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 activated (it is already
in the home position).
After the operation, M712 returns to its home
position based on PS716 (gate HP).
