4. Document stopper (MP730 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 roller (MP730 only)
The document pickup roller is used to pick up a document and feed it to the separation
roller.
6. Separation guide (MP730 only)
Separates the documents to prevent double-feeding.
7. Separation roller (MP730 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 release lever (MP730 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 (MP730 only)
The U-turn roller is used to feed a document to the document feeder roller.
10. Document edge sensor (MP730 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 SPCNT board.
11. Document feed roller (MP730 only)
This roller feeds documents to the contact sensor after they are separated by separation
roller.
12. Document retainer (MP730 only)
This retainer prevents a document from its floating while scanning.
13. Document eject roller (MP730 only)
This roller ejects documents fed from the document feed roller.
14. Flatbed motor
The flatbed motor is used to drive the contact sensor.
15. Contact sensor drive belt
The contact sensor drive belt is used to covey the driving force of the flatbed motor to the
contact sensor.
16. Contact sensor shaft
The contact sensor shaft is used to keep the direction of the driving force of the contact
sensor.
17. Color contact sensor
The color contact sensor scans the image data from the document, converts it to Red, Green
and Blue serial data, and transmits it to the SPCNT board as electrical signals.
