Usually, reversing a shredder is independant of the paper sensor. The paper
sensor only detects whether paper is inserted for shredding and the motor always
goes forward automatically. Only on paper jams does the motor need to reverse,
and that is accomplished by a manually operated reversing switch. That's how it
works on my old Fordigraph 100 Auto anyway.
