The sheet through type ADF feeds the document from the top page of the document stack on the table. The pick-up [A] and feed roller [B] feed the original into the scanner, and the separation roller [C] helps to feed one sheet at a time. Then, the R0 [D], R1 [E], and R2 [F] rollers feed the document through the scanner. At the time of scanning the document, the scanner ([B] on the previous page) moves down to the scanning position under the exposure glass [G]. The shading plate [H] pushes the document to the exposure glass at the scan line, so that the document is within the image sensor�s range of focus. After scanning, the ADF feeds out the document onto the platen cover, and the scanner moves back to its home position at the right end of the scanner. Unlike a copier�s ADF, this ADF does not have a document length sensor. So, some of the copier features are not available when the ADF is used. Refer to �Original Detection - ADF� later in this chapter.
