6 MECHANICAL FUNCTION

6.1. Paper Feed Mechanism-1 (Auto)
1. When documents are set on the Hopper, and the scanning command is issued from PC, the Hopper rises and the documents
will be brought into contact with Paper Feed Roller.
2. The Conveyor Motor is driven to rotate the 3 Drive Rollers, 3 Conveyor Rollers, and Exit Roller.
3. When the Paper Feed Motor starts, the Paper Feed Roller and the Separation Roller turn in feed direction.
The Retard Roller is supported by a shaft fixed via a torque limiter, and it is pushed against the Separation Roller. When the
document enters into the separation section, the Retard Roller exerts a manipulation force onto the documents, which depends
on the set torque. In case of continuous paper feed, the documents are separated by this manipulation force, and so only a
document is fed to the scanning section.
4. When the leading edge of the document advances at about 5 mm from the Waiting Sensor after passing through the separation
section and Waiting Sensor, the Paper Feed Motor stops and the Paper Feed Roller and the Separation Roller turn together.
5. When the leading edge of the document passes through the Starting Sensor, scanning the image starts after the defined period.
(Time to be required to conveyor the document from the Starting Sensor to the scanning start point.)
6. When the heeling edge of the document come to the defined position from the Waiting Sensor, the Paper Feed Motor is driven
again to feed the 2
7. Repeat the above 3 to 6.
8. After finishing all scanning process, Hopper goes down to the original position and the series of scanning sequence ends.
Note:
When the scanner's buffer becomes full of data, scanner will stop until securing the buffer free area that allows the
scanner transfer the data to PC in order to prevent the buffer from overflowing.
