2.6.1 Basic Operation

After stream reading on the document glass, the document is delivered to the document delivery unit as discussed below.
a. Document feed/delivery
After moving past the reading position, the document is fed by the delivery reversal roller driven by the feed motor (M1) turning in the forward direction. The
deliver reversal motor is normally pressurized; the roller release solenoid turns on only when the document is reversed for duplex printing.
