Duplex document
For duplex document sheets, feed is performed in the following sequence:
1. The first document sheet is fed to the ADF transport roll assembly.
2. The document is fed to the ADF registration roll assembly, and then fed to the scan feed reference
position.
3. The document sheet is fed at the feed speed corresponding to the selected magnification, and the image
on it is scanned with the exposure lamp at the scan position.
4. As the image is scanned on both sides, the document sheet is fed and ejected by the ADF feed-out roll
assembly and ADF exit roll assembly that are driven by the ADF transport motor.
