Inverting Automatic Document Feeder (i-ADF)The i-ADF (Inverting Automatic Document Feeder) automatically feeds documents into the unit, oneoriginal at a time. When duplex mode is selected, this feature enables two-sided faxing or copying ofthe original(s).Its main features are:1. Place originals Face-Up2. Correct Order Stacking (Collation Mode)3. Paper Feed Mechanism with Pre-Feed RollerThe following is the ADF / i-ADF Mechanical operation description.6.4.1. Automatic Document Feeder Operation1. InitializationThe ADF begins its operation by turning on the Feed Motor for a specified time, lowering the PickupRoller to re-set the Original Stopper 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 Original Stopper(513).Adjust the Original Guides (403, 406) to center the original on the ADF. The Original Stopper (513)prevents originals from skewing and multiple feeding. The Original Detection Sensor (401) detects thepresence of documents on the ADF when the original(s) actuate Original Sensor Actuator (521) on theADF Cover. The two Sensors mounted on the SNS PC Board which is installed in the Original Tray areactuated by the Original Guides (403, 406), their position determines the original's width and theOriginal Length Sensor 1 (401) and Length Sensor 2 (401) detect the length of the original.3. Feeding and SeparationWhen the Start button is pressed, the ADF Motor 1 (925) starts to rotate and drive the Pickup Roller(511). The 1st original is fed into the Paper Feed Roller (508) and the Separation Roller (610) with theTorque Limiter Assembly preventing multiple feeding.4. Transmission and EjectionThe original is fed into the Registration Roller 1 (817) and when the original actuates the RegistrationSensor 2 (401), the Paper Feed Roller (508) stops rotating. The Registration Sensor 2 (401) detectsthe scanning position and the Registration Roller 2 (818) and Transport Roller (816) transport theoriginal while scanning. The Stamp Head (724) stamps an [X] mark on the front of the original after thedocument is successfully transmitted or stored. It consists of the Stamp Head (724) and StampSolenoid (726). The Exit Roller (814) feeds and ejects the original out of the ADF. If there are additionaloriginals on the ADF, the next one is fed into the feeder.5. Final OperationAfter ejecting the last original from the ADF, the Clutch reverses the direction of rotation raising theOriginal Stopper (513) to its standby position.6.4.2. i-ADF OperationThe i-ADF automatically inverts 2-sided original(s) for faxing or copying of the second side. Thisfeature enables your machine to perform duplex faxing or copying.An i-ADF (Inverting Automatic Document Feeder) functions like the ADF with the main exception beingthe original eject path after scanning. The following is the description of the main differences.1. Switching from the ADF Mode to the i-ADF ModeAfter passing through the Read Point, the path of the original is switched over by the Selection Guide 1(815), to the Exit Roller (814) or to the Inverting Roller (809). For single-sided scanning, the Selection
