Correction
Sensor
First, the feed motor rotates forwards: The feed belt feeds the
original, but the skew correction roller does not turn.
The leading edge of the original hits the skew correction roller, and
this removes any skew in the original.
Then, soon after the skew correction sensor detects the original,
the feed motor stops.
Then, the feed motor turns in reverse: The feed belt and skew
correction roller both turn. The feed belt stops when the feed
clutch turns off.
Slide 271
The one-way clutches in the ADF mechanism allow the feed motor to have
different effects when rotating forwards and in reverse.
