2.2.4 SKEW CORRECTION
When an original is fed into the feeder, the feed motor [B] rotates forwards. At this time, the
feed belt turns but the skew correction roller [C] does not. Because of this, when the
leading edge of the paper gets to the skew correction roller, skew in the original is removed.
A short time after the leading edge of the original turns on the skew correction sensor [A],
the feed motor [B] turns off for 40 ms and rotates in reverse. At this time, the skew
correction roller [C] and the feed belt both turn, and original feed continues.
The original is fed by the skew correction roller after the feed clutch [D] has turned off.
