■ Read Control

When the edge of an original reaches the reading position, stream reading is started by
sending the image leading edge signal to the host machine. Stream reading is a mode to
move an original on the host machine's fixed scanner glass by the Feed Roller and scan it.
The read original is stored in the machine's memory.

● Basic operation
There are 2 types for the reverse operation of original: From the front side to the back side,
and from the back side to the front side.
Here, the reverse operation from the front side to the back side is explained as the above 2
types of reverse operation are basically the same.
● Pickup of front side
1) The drive (clockwise rotation) of the ADF Motor (M02) rotates the Feed Roller, and reads
the front side of an original.
2) When reading is completed, the Delivery Roller rotates to feed the original to the ejection
area.
3) When the original has been fed for a certain distance, the ADF Motor (M02) stops.
