Scanning The Front And The Back Side Of An Original; Eject By Reverse Rotation; Sub Tray - Panasonic DP-C305 Service Manual

It will remain in this position until a different operation is performed (i.e. if the last operation was
2-Sided scanning, a Single-Sided 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
Selection Guide 1, and Selection Guide 2.
After the Front side of the original is scanned, the original is transported through the Selection Guide 1,
through the Selection Guide 2 that was rotated counter-clockwise by the Selection Solenoid, and is
carried beyond the Inverting Roller and upper Pinch Rollers into the Sub Tray. The original is carried for
a specified period of time after the trailing edge of the original triggers the Selection Sensor, and stops
within 10 to 20 mm from exiting the rollers. Then, the Selection Guide 2 is rotated clockwise by the
Pinch Roller Solenoid Assembly, and the reverse rotation of the ADF Motor 1 pulls the original back
around the Registration Roller 1, and proceeds to scan the Back side of the original.

3. Eject by Reverse Rotation

After the Back is scanned, the original is transported through the Selection Guide 1, through the
Selection Guide 2, and is carried beyond the Inverting Roller and lower Pinch Rollers, into the Sub
Tray, again stopping 10 to 20 mm from exiting the rollers.
The Selection Guide 2 is rotated clockwise by the Pinch Roller Solenoid Assembly, and the reverse
rotation of the ADF Motor 1 pulls the original back around the Registration Roller 1, however, this time
the original is routed to the Exit Roller, and exits into the ADF Base.

4. Sub Tray

The Inverting ADF system includes a Sub Tray, which supports the originals during the ejection mode
of the 2-Sided scanning operation.
