Inverting Automatic Document Feeder - Panasonic DP-8032 Service Manual

mark on the front of the original after the document is successfully transmitted or stored. It consists of
the Stamp Head (1636) and Stamp Solenoid (1635). The Exit Roller (1751) feeds and ejects the
original out of the ADF. If there are additional originals on the ADF, the next one is fed into the feeder.
5. Final Operation
After ejecting the last original on the ADF, the Clutch reverses the direction of rotation raising the
Document Stopper to its standby position.

Inverting Automatic Document Feeder

The i-ADF automatically inverts two-sided original(s) for faxing or copying of the second side. This feature
enables machines with a duplexer mounted to perform duplex copying.
An i-ADF (Inverting Automatic Document Feeder) functions in a similar manner as the ADF (Automatic
Document Feeder), with the main exception being the document eject path after scanning. The following is
the description of the main differences.

1. Switching from the ADF mode to the i-ADF mode
After passing through the Read Point Sensor (1045), the path of the original is switched over by the
Duplex 2 Guide (1857), to the Exit Roller (1751) or to the Inverting Feed Roller (1853).For single-side
scanning, the Duplex 2 Guide is rotated clockwise by the Solenoid (1770) guiding the original to the
Exit 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, in
the direction according to whether a single or double-side scanning is selected (Copier or Fax) before
the Start button is pressed.
It will remain in this position until a different operation is performed (i.e. if the last operation was 2-sided
scanning, a single-side scanning is performed).
2. Scanning the Front and the Back Side of an Original
The scanning of the Front and Back side of a 2-sided original is accomplished by means of the Duplex
2 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 is
carried 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 the
Duplex 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 ADF
Motor (1801) pulls the original back around the Feed 2 Roller (1753) and proceeds to scan the Back
