CHAPTER 2 OPERATION OVERVIEW

1. Drive gear rotates in the linkage with the rotation of the feed motor (M1). At this time, the reversing main gear, forward gear, and reversing gear do not rotate since the cam is fixed with the catch of the reversing solenoid.

2. When the inlet sensor (PI9) detects the trailing end of the paper, the reversing solenoid (SLI) is turned ON once and the solenoid catch releases the cam. At the same time, the reversing main gear reaches the drive gear under the spring force of the arm and starts rotating in the direction of the arrows. The forward gear rotates in the linkage with the reversing main gear. When the forward gear is engaged with the reversing relay gear, the driving force is transmitted to the reversing roller gear and the reversing roller rotates in the forward direction. 3. When the forward gear is disengaged from the reversing relay gear, the reversing relay gear and reversing roller gear stop rotating.

4. The reversing gear rotates in the linkage with the reversing main gear, the reversing gear is engaged with the reversing roller gear and the reversing roller reverses.
