232DP-8032/80252008Ver.1.26.5. Automatic Document FeederThe ADF (Automatic Document Feeder) automatically feeds paper into the unit, one original at a time. Itsmain features are:1. Place originals Face-Up2. Correct Order Stacking (Collation Mode)3. Paper Feed Mechanism with Pre-Feed Roller4. Oversized Feed 2 Roller for stable scanningThe following is the ADF/i-ADF Mechanical operation description.6.5.1. Automatic Document Feeder1. InitializationThe ADF begins its operation with the Eject phase in order to feed and eject any documents stuckinside the ADF. The Clutch (1788) starts rotating and lowering the Original Stopper (1737) and the Pre-Feed Roller (1731), after a few seconds the Clutch reverses the rotation direction raising the DocumentStopper to its standby position.2. Original Setting and Size SensorsPlace the original(s) face up on the ADF until the leading edge stops against the Document Stopper.Adjust the Original Guides (1605 & 1606) to center the original on the ADF. The Document Stopperprevents originals from skewing and multiple feeding. The Original Detection Sensor (1045) detects thepresence of documents on the ADF when the original(s) actuate Actuator 1 (1836) on the ADF Cover(1831). The two Sensors mounted on the SNS PC Board (19116) which is installed in the ADF InputTray (1604) are actuated by the Original Guides, their position determines the original's width and theOriginal Length Sensor1 (1045) and Length Sensor2 (1045) detect the length of the original.3. Feeding and SeparationWhen the Start button is pressed, the Clutch (1260) starts to rotate and lowers the Document Stopper,causing the Pre-Feed Roller (1731) to apply a downwards pressure against the originals. After a fewseconds, the Clutch (1260) reverses the direction of rotation and the Pre-Feed Roller is raised upwardsalong with the Document Stopper. The upper original is fed to the ADF Roller (1728), and theSeparation Roller (1740) with Torque Limiter prevents multiple feeding.4. Transmission and EjectionThe original is fed into the Drive Roller (3205) and when the original actuates the Read Point Sensor(1045), the ADF Roller stops rotating. The Eject Sensor (1045) detects the scanning position and theFeed 2 Roller (1753) transports the original while scanning.
