Paper Feed Mechanism (Auto feeding Mode)
Fig. 7.1
1. When the Paper Sensor detects the document and the scan start command is received from the computer, the Conveyor Motor
will start to drive the Paper Feed Roller, Conveyor Roller, and Exit Roller in the direction of the arrows.
2. When the document enters the separation section, the DFP 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.
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.
3. When the leading edge of the document advances to the Conveyor Roller position, the document is fed at a speed that is 1.9
times as fast as the speed of the Paper Feed position.
4. When the leading edge of the document pushes down the Starting Sensor’s arm, the leading edge is detected, and scanning will
start after a certain period of time determined.
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
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.)
6. The steps 2 to 5 above are repeated.
7. When the Paper Sensor detects no further documents, and the Starting Sensor detects the trailing edge of the document, the
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.
