motor (M2) slows down.

position, and scanning starts when the original reaches and stops at a specific position.

5. When scanning ends, the 2nd original is separated; the separation motor is stopped once 100
msec after the separation sensor has turned on.
When the reversal inlet sensor (SR5) detects the leading edge of the original (ON), the reversal
delivery motor (M3) starts to rotate clockwise.
The reversal delivery flapper remains closed while the reversal delivery motor is rotating
clockwise.
