2. Document Detection
The document sensor [A] detects when a document is placed in the ADF.
The B4 width sensor [B] detects when the width of a document is over A4 or
LT. The scan line sensor [C] detects the leading edge of the document at the
scan line.
3. Prefeeding and Separation
The plate [A] aligns the leading edges of the pages of the document. When
the document sensor detects a document in the ADF, the machine starts pre-
feeding the document. The ADF roller [A] feeds the bottom sheet of the
document. Then, the R1 roller [C] feeds the sheet into the scanner.
The separation rubber plate [D] prevents the ADF roller from feeding more
than one sheet at a time.
