7.1.
Paper Feed Mechanism
1. When the document is set on the Feed Tray, and is detected by the Paper Sensor, the scanning command from the PC will
start the Conveyor Motor, which will move down the Document Stage and open the Gate, and rotate the Paper Feed Roller,
Conveyor Roller, and Exit Roller in the direction of the arrows.
Conveyor Roller, and Exit Roller in the direction of the arrows.
2. When the document enters the separation section inside the paper feed section, the Double Feed Prevention Roller
(supported by a shaft fixed via a torque limiter) exerts force onto the document, which depends on the set torque.
When the paper is fed continuously, the 1st document is separated from the 2nd or more documents by this force, and is fed
to the scanning section.
If a Double Feed occurs when Double Feed detection mode has been set in the scanning software, the scanner will stop the
scanning process.

If a Double Feed occurs when Double Feed detection mode has been set in the scanning software, the scanner will stop the
scanning process.
3. When the leading edge of the document advances to the Conveyor Roller position, the document is fed at a speed that is 2.3
times as fast as the speed of the Paper Feed position.
4. When the leading edge of the document is detected by the Starting Sensor, scanning will start after a certain period of time

determined by the scanner.
5. When the trailing edge of the document passes through the separation section, the continuous rotation of the Paper Feed
Roller during scanning, enables the next document to be fed.
(A difference in the rotation speeds of the Conveyor Roller and Paper Feed Roller creates a distance between the1st
document and the 2nd.)

7. When the Paper Sensor detects no further documents, and the Starting Sensor detects the trailing edge of the document, the
Conveyor Motor will stop rotating after a certain period of time determined by the scanner to end the scanning sequence.
8. After the conveyor motor stopped, by opposite rotation of the Conveyor Motor, the Document Stage is moved up and the
Gates are closed.
Note:
When the scanner’s buffer becomes full, the scanner stops to prevent buffer overflow, while allowing the data to be
transferred to the PC continuously. When enough free buffer space is secured again, the scanner resumes the
scanning process.

scanning process.

Flatbed Mechanism
1. When paper is set on the Flatbed Glass, and the scanning command is issued from the PC, the controller in the CONTROL
Board confirms its default position, and then the Carriage Motor rotates to drive the Scanning Unit.
2. After the Scanning Unit moves to the specified area according to scanning instructions sent from the PC, the Carriage
Motor will rotate in reverse so that the Scanning Unit returns to its home position.
