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

registration is not appropriate. This is because the IIT Lead Edge Registration
affects the precision of the document size detection, etc..
Before performing this procedure, make sure that the IOT Lead Edge Registration is
correct. [Refer to ADJ1. 1. 9 IOT Side/Lead Edge Registration.]
