233DP-8032/80252008Ver. 1.2mark on the front of the original after the document is successfully transmitted or stored. It consists ofthe Stamp Head (1636) and Stamp Solenoid (1635). The Exit Roller (1751) feeds and ejects theoriginal out of the ADF. If there are additional originals on the ADF, the next one is fed into the feeder.5. Final OperationAfter ejecting the last original on the ADF, the Clutch reverses the direction of rotation raising theDocument Stopper to its standby position.6.5.2. Inverting Automatic Document FeederThe i-ADF automatically inverts two-sided original(s) for faxing or copying of the second side. This featureenables machines with a duplexer mounted to perform duplex copying.An i-ADF (Inverting Automatic Document Feeder) functions in a similar manner as the ADF (AutomaticDocument Feeder), with the main exception being the document eject path after scanning. The following isthe description of the main differences.1. Switching from the ADF mode to the i-ADF modeAfter passing through the Read Point Sensor (1045), the path of the original is switched over by theDuplex 2 Guide (1857), to the Exit Roller (1751) or to the Inverting Feed Roller (1853).For single-sidescanning, the Duplex 2 Guide is rotated clockwise by the Solenoid (1770) guiding the original to theExit Roller. For double-side scanning, the Duplex 2 Guide is rotated counter-clockwise by the Solenoid(1770) guiding the original to the Inverting Feed Roller (1853).The Duplex 2 Guide moves only once, inthe direction according to whether a single or double-side scanning is selected (Copier or Fax) beforethe Start button is pressed.It will remain in this position until a different operation is performed (i.e. if the last operation was 2-sidedscanning, a single-side scanning is performed).2. Scanning the Front and the Back Side of an OriginalThe scanning of the Front and Back side of a 2-sided original is accomplished by means of the Duplex2 Guide (1857) and Inverting 1 Guide (1858).After the Front side of the original is scanned, the original is transported through the Duplex 2 Guide,through the Inverting 1 Guide (1858) that was rotated counter-clockwise by the Solenoid (1762) and iscarried beyond the Inverting Feed Roller (1853) and upper Pinch Rollers (1838) into the Sub Tray(1617).The original is carried for a specified period of time after the trailing edge of the original triggers theDuplex Eject Sensor (1045) and stops within 10 to 20 mm from exiting the rollers.Then, the Inverting 1 Guide is rotated clockwise by the Solenoid and the reverse rotation of the ADFMotor (1801) pulls the original back around the Feed 2 Roller (1753) and proceeds to scan the BackInverting Automatic Document FeederSeparationRoller(1740)ADF Roller(1728)Pre-Feed Roller(1731)Original Detection Sensor (1045)Release LeverPlate (1735)38DocumentStopper(1737)Exit Roller (1751)Inverting Feed Roller (1853)Pinch Roller (1627)Pinch Roller (1627)Duplex 2 Guide (1857)Inverting 1 Guide (1858)Stamp Head (1636)Sub Tray (1617)Reversing 1 Guide (1752)Read PointPinch Roller (1838)(Reverse Registration or Feed Skew Adjustment)Pinch Roller(1838)(Feed Skew Adjustment)Pinch Roller(1838)(Registration Adjustment)Feed 2 Roller(1753)Drive Roller(1872)Eject Sensor(1045)Duplex EjectSensor (1045)Read PointSensor (1045)210 (A5)215.9 (INVOICE)257 (B5-R)297 (A4-R)330.2 (FLS1.2)364 (B4)420 (A3)431.8 (Ledger)
