to remove the skew. (For details of pickup operation, see 2.4 "Picking Up/Separating

2) The registration roller and the feeding belt are rotated to move the original.
When the trailing edge of the 1st original moves past the point of contact [1] of the
pickup roller, the 2nd original is started.

movement of the original starts in step 4.)
