Names and function of parts
1. Paper Guide (SmartBase MPC600F only)
When properly adjusted to the width of the documents, the guide will hold documents in the
horizontal direction to prevent them from skewing when fed.
2. Document feed motor (SmartBase MPC600F only)
This motor drives all the rollers in the scanner sections.
3. Document Sensor (DS, SmartBase MPC600F only)
This sensor uses an actuator to detect the presence of documents to be scanned, and sends that
information to the SCNT board by the way of the ADF board.
4. Document stopper (SmartBase MPC600F only)
This stopper is located to the side of the separation rollers, and prevents documents from
entering too far inside the scanning section. This stopper is located here to improve document
loading and prevent double feeding or non-feeding due to defective loading of documents.
5. Document pickup rollor (SmartBase MPC600F only)
The document pickup roller is used to pick up a document and feed it to the
separation roller.
6. Separation guide (SmartBase MPC600F only)
Separates the documents to prevent double-feeding.
7. Separation roller (SmartBase MPC600F only)
This roller uses difference in the coefficients of friction of the separation guide, document and
separation roller to separate each of the sheets in a multiple-page document.
8. Document feed lever (SmartBase MPC600F only)
This lever switches between automatic document feed and manual document feed. Damage to
the document caused by the separation roller can be minimized by switching to the manual
document feed position when sending single sheets such as thick-stock paper or photographs.
9. U-Turn roller (SmartBase MPC600F only)
The U-turn roller is used to feed a document to the document feeder roller.
10. Document edge sensor (DES, SmartBase MPC600F only)
Using an actuator, the DES detects the edge of a document just before it reaches the contact
sensor, and sends this information to the SCNT board.
11. Document feed roller (SmartBase MPC600F only)
This roller feeds documents to the color contact sensor after they are separated by separation
roller.
12. White sheet
This white sheet is used as a whiteness reference when pre-scanning documents.
13. Contact sensor drive motor
The flatbed motor is used to drive the contact sensor.
14. Contact sensor drive belt
The CS belt is used to covey the driving force of the flatbed motor to the contact
sensor.
15. CS shaft
The CS shaft is used to keep the direction of the driving force of the contact sensor.
16. Color contact sensor
The color contact sensor scans the image data from the document, converts it to serial data, and
transmits it to the SCNT board as electrical signals. The color contact sensor has a scanning
resolution of the 600dpi and outputs Red, Green and Blue analog image data.
17. Paper eject roller (SmartBase MPC600F only)
This roller ejects documents fed from the document feed roller.
