An operation panel setting determines whether the original exits the upper exit [A]
or rear exit [B]. When the upper exit is selected, the solenoid stays off, and the
original exits at the upper exit. This is the default setting.
When the rear exit key is selected, the solenoid switches on when the registration
sensor detects the leading edge of the original, and the original exits at the rear [B].
