Skew Correction Mechanism
After the original feeds, the skew correction sensor detects its leading edge, and stops the rotation of the feed motor for a prescribed number of pulses.
The leading edge hits and straightens against the stationary roller to correct skew.
If the original is small (B6, A5, B5, HLT) (or when duplex scanning regardless of paper size), when the interval sensor [E] detects the leading edge of the original, it stops the pre-scanning roller [D] for a prescribed number of pulses, long enough for the original to buckle against the stationary roller and correct skew.

You can turn on SP6020-001 (ADF Contact Mode In/Out) to enable skew correction at both the entrance roller above as well as the pre-scanning roller below for all paper sizes but this may slow down the speed of original feeding.
