Document feed path from the ADF

Shown below is the document feed path from the ADF.
Simplex and duplex document feed
For two simplex 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, 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.
5. When the trail edge of the first document sheet has passed through the sensor (sheet through),
the feed of the second document sheet starts.
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.
