2. DESCRIPTION OF OPERATION
(4) Paper reversing and paper multi-feeding
1. In a certain period of time after the paper rear end passes the eject sensor
lever, the eject motor runs backward (clockwise) and then the eject roller
rotates in the reverse direction (clockwise).
2. By the inverse rotation of the 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.

(3) Fuser unit and paper ejecting
1. The fuser unit is driven by the DC motor. After the DC motor starts running
(clockwise), the heat roller starts rotating.
2. Simultaneously the eject motor starts running (counterclockwise), and then
the eject roller starts rotating and ejects paper.
