4. Then, the leading edge of the document advances to the Drive Roller 1 position, and then passes through the Slip Detect Sensor.
At this time, if the document does not advance within a defined period, the pressure applied to the Separation Roller from the
Double-feed Prevention Roller is strengthened to prevent the document from slipping.
(For the pressure mechanism, see Fig. 6.1.2.)
When the leading edge of the document reaches the Slip Detect Sensor, the Paper Feed Motor will stop.

5. When the leading edge of the document passes through the Starting Sensor, image scanning starts after a defined period.
(i.e., the time required for the document to advance from the Starting Sensor to the scanning start point)

6. The document passes through the Exit Sensor and exits from the scanner.
7. When the trailing edge of the document passes through the Waiting Sensor, the Paper Feed Motor is driven again to feed
the 2nd document.

8. 2 to 7 above are repeated.
Note:
When the scanner’s buffer becomes full, the scanner stops to prevent buffer overflow, while continuing
to allow data to be transferred to the PC.

Paper Feed Mechanism (Manual)
When scanning multipart paper with the Manual Feed Selector set to “AUTO”, the Double-feed Prevention Roller is
pressed against the Separation Roller, and this results in a separating force being applied to the document, which will separate
the layers, resulting in damage to the document.
This problem can be avoided by scanning multipart paper with the Manual Feed Selector set to "Manual".
With “MANUAL” set, the Double-feed Prevention Roller's gear is released from the Paper Feed Pitch Roller, and so multipart paper
can be fed and scanned as if it were a single sheet of paper.
(In this case, the Double-feed Prevention Roller operates as a free roller.)

Paper Feed Operation
1. When the Paper Feed Motor rotates the Paper Feed Motor in the paper feed direction, Paper Feed Roller will go down
until the roller is in contact with, and then rotate in the paper feed direction. (Arrows 1
