This control reverses a printed sheet of paper for printing on the second side.
The DC controller monitors the fuser delivery paper sensor (PS7) and controls the delivery
motor (M2). The following is the sequence of reversing paper.

2. When the end of the paper is detected by the fuser delivery paper sensor (PS7), the
delivery motor (M2) rotates counterclockwise after a specified period.
