2.2.4 SKEW CORRECTION
When an original is fed into the feeder, the feed motor [A] rotates forwards. At this time, the feed
belt turns but the skew correction roller [B] does not, because these rollers have a one-way gear.
(If the ADF feed motor rotates forward, the feed belt is moved. If the ADF feed motor rotates in
reverse, the skew correction roller is moved.) As a result, 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 [C], the feed
motor [A] turns off and rotates in reverse. At this time, the skew correction roller [B] and the feed
belt [D] both turn, and original feed continues.
The registration roller also has the same skew correction mechanism, but only for small size
originals (6, A5 or HLT). This function can be effective for all size paper with SP6-020-001.
