Reading at ADF
1) When the ADF paper sensor (SR718) detects the document on the document tray, the ADF pickup motor (M13) works and the ADF pickup roller descends to
the surface of the document.
2) A document set on the document ray is transported to the ADF separation roller by the ADF pickup roller while being pressed by the slide guide so that it does
not skew.
3) Only one sheet of document is separated by the ADF separation roller and the ADF separation pad.
4) The document is transported to the reading glass surface by the ADF feed roller.
The ADF paper trailing edge sensor (SR719) detects the leading edge of the document.
5) While being transported by the ADF feed roller, the document is read by the CCD unit.
6) The document is delivered on the ADF delivery tray by the ADF delivery roller.
A 2-sided original with its first side read is delivered to the reading position again with the reversal path.
