Paper Feed Mechanism (Auto)
(Fig. 6.1.1)
1. When the documents are set on the Hopper and the scanning command is issued from PC, the Hopper rises until hopper
position sensor detects the documents.
position sensor detects the documents.
2. Then conveyor Motor will be driven to rotate the three Drive Rollers (Drive Roller 1 to 3) and Exit Roller, and the Paper
Feed Motor will be driven to rotate the Paper Feed Roller and the Separation Roller in the feed direction.
At this time, the Paper Feed Roller will move down until the roller is in contact with the documents, which enables
the roller to feed the documents.
The Double-feed Prevention Roller is supported by shaft fixed via a torque limiter, and it is pushed against the Separation Roller.
3. When documents enter the separation section, the Double-feed Prevention Roller exerts a manipulation force onto them,
which depends on a set torque. In the case of continuous paper feed, the documents are separated by this manipulation force,
so only one sheet of the documents is fed to the scanning section.
When the document passes through the Waiting Sensor, the Paper Feed Motor will be driven to rotate the Double-feed
Prevention Roller in the reverse direction to ensure separation of the first document from the following documents. At this time,
the Paper Feed Roller rises to separate from the documents.
