6.5. Automatic Document Feeder
The ADF (Automatic Document Feeder) automatically feeds paper into the unit, one original at a time. Its
main features are:
1. Place originals Face-Up
2. Correct Order Stacking (Collation Mode)
3. Paper Feed Mechanism with Pre-Feed Roller
4. Oversized Feed 2 Roller for stable scanning
The following is the ADF/i-ADF Mechanical operation description.
6.5.1. Automatic Document Feeder
1. Initialization
The ADF begins its operation with the Eject phase in order to feed and eject any documents stuck
inside 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 Document
Stopper to its standby position.
2. Original Setting and Size Sensors
Place 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 Stopper
prevents originals from skewing and multiple feeding. The Original Detection Sensor (1045) detects the
presence 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 Input
Tray (1604) are actuated by the Original Guides, their position determines the original's width and the
Original Length Sensor1 (1045) and Length Sensor2 (1045) detect the length of the original.
3. Feeding and Separation
When 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 few
seconds, the Clutch (1260) reverses the direction of rotation and the Pre-Feed Roller is raised upwards
along with the Document Stopper. The upper original is fed to the ADF Roller (1728), and the
Separation Roller (1740) with Torque Limiter prevents multiple feeding.
