F-8-48
2. The inside delivery sensor (PS35) goes on and the paper moves over a specific distance; then, the reversal motor (M14) goes on to stop the trailing edge of paper
at the point of reversal, timed to coincide with the activation of the reversal sensor 1 (PS37).

3. The reversal motor (M14) starts to rotate once again, and the trailing edge of paper is moved in the direction of delivery.

4. When the trailing edge of paper moves past the reversing roller coinciding with the activation of the outside delivery sensor (PS36), the reversal motor (M14)
stops. The delivery motor (M13) starts to rotate to move the paper to the outside delivery roller, which discharges the paper to the outside of the machine.
