Purpose
To adjust the IIT scan timing in the Slow Scan direction and to cor-
rect the copy position.

when the actual IIT Regi is not appropriate. This is because the IIT
Lead Edge Registration affects the precision of the document size
detection, etc.

Lead Edge Registration is appropriate. (Refer to
Side/Lead Edge Registration.)
