(4) Paper reversing and paper multi-feeding
1. TRemoving the first eject roller at the rear part of paper and set the solenoid as ON for a while, then the
planet gear starts to move, the second eject roller starts inverse rotating (Counterclockwise rotation).
2. By the inverse rotation of the second eject roller the paper is inversely rotated and conveyed to Duplex.
3. Paper is conveyed by Duplex conveying roller.
4. After setting the entrance sensor lever as ON, paper bumps into the stopped resist roller, still a certain
more amount of paper is conveyed. (This corrects the skew of paper.).
5. If set the Resist clutch as ON, paper is conveyed by Resist roller.
