6.3. 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.
For DP-2010E only.
1. Switching from the ADF mode to the i-ADF mode
After passing through the Read Point Sensor (604), the path of the original is switched over by the
Duplex 2 Guide (2138), to the Exit Roller or to the Inverting Feed Roller (2135).For single-side
scanning, the Duplex 2 Guide is rotated clockwise by the Solenoid guiding the original to the Exit
Roller. For double-side scanning, the Duplex 2 Guide is rotated counter-clockwise by the Solenoid
guiding the original to the Inverting Feed Roller (2135).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 (2138) and Inverting 1 Guide (2139).
After the Front side of the original is scanned, the original is transported through the Duplex 2 Guide,
through the Inverting 1 Guide (2139) that was rotated counter-clockwise by the Solenoid and is carried
beyond the Inverting Feed Roller (2135) and upper Pinch Rollers (653) into the Sub Tray (1910).
The original is carried for a specified period of time after the trailing edge of the original triggers the
Duplex Eject Sensor (604) 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 pulls the original back around the Feed 2 Roller (2034) and proceeds to scan the Back side of
the original.
After the Back side is scanned, the original is transported through the Duplex 2 Guide, through the
Inverting 1 Guide and is carried beyond the Inverting Feed Roller and lower Pinch Rollers (653) this
time, into the Sub Tray, again stopping 10 to 20 mm from exiting the rollers.
3. Eject by Reverse Rotation
For the originals to stack properly, the above process repeats one more time. The Inverting 1 Guide is
rotated clockwise by the Solenoid and the reverse rotation of the ADF Motor pulls the original back
around the Feed 2 Roller, however, this time the original is routed to the Exit Roller (2032) and exits
into the ADF Base.
4. Sub Tray
The Inverting ADF system includes a Sub Tray (1910), which supports the originals during the ejection
mode of the double-side scanning operation.
The Release Lever Plate grasps the originals and prevents them from being ejected into the Sub Tray.
