The sheet through-type ADF feeds the document from the top of the document
stack.
The pick-up roller [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 [H] rollers feed the document through the scanner.
During scanning, the scanner [I] moves to the scanning position under the
exposure glass [G]. The shading plate [F] secures the document at the scan line,
ensuring that the document is within the image sensor's range of focus.
After scanning, the ADF feeds the document onto the platen cover, and the
scanner moves back to its home position.
