1. When the documents are set on the Feed Tray and the scanning command is issued from PC, the Conveyor Motor will run in 

reverse to open the gate and then run in forward to rotate the three Drive Rollers (Drive Roller 1 to 3) and Exit Roller.

2. Then, 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 DFP 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 DFP Roller exerts a manipulation force onto them, which depends on a set 

torque.  In the case of the Auto mode, the documents are separated by this manipulation force, so only one sheet of the doc-
uments is fed to the scanning section.

4. When the document passes through the Waiting Sensor, the Paper Feed Motor will be driven to rotate the DFP 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.

5. Then, the leading edge of the document advances to the Drive Roller 1 position and when it reaches the Starting Sensor, the 

Paper Feed Motor will stop.

6. 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 Sensor to the scanning start point).

7. Then, the leading edge of the document passes through the Jam (Imprinter Starting) Sensor. If an optional Imprinter is 

installed, the printing starts after a defined period (i.e., the time required for the document to advance from the sensor to the 
printing start point).

8. The document passes through the Exit Sensor and exits from the scanner.
