The scan document enters the ADF from the ADF tray through the pick roller and the separator roller. It moves
to the paper feed 1 roller for document skew correction. It passes by the paper feed 2 roller and then moves
to the scan area for scanning.
After scanning, the scan document exits to the ADF bin through the exit roller if the scan job is a one-sided job.
For a two-sided scan job, the scan document reenters the ADF through the exit roller. It returns to the paper
feed 1 roller for document skew correction again. It passes by the paper feed 2 roller and then moves to the
scan area for scanning the opposite side. After scanning, the scan document exits to the ADF bin through the
exit roller.
