  • Page 59 Chapter 2   b. Reversing/Feeding the Original 1 The delivery reversal motor (M3) stops when the trailing edge of the original moves past the delivery reversal sensor (PI9); immediately thereafter, the delivery reversal motor (M3) starts to rotate in reverse so that the original will arch against the No. 2 registration roller. At the same time, the locking solenoid goes off to move the delivery reversing roller away.
  • Page 60: Sequence Of Operation

    Chapter 2 c. Reversing/Moving the Original 2 The machine rotates the feed motor in normal direction and the delivery reversal motor in reverse to move sheets at the same time. The machine stops the delivery reversal motor when the originals have moved a specific distance. The machine then drives the lock motor for a specific number of pulses to lock the platen upstream roller in place.
