When AXIS has been selected for the registration mark mode, axis adjustment is performed manually. If 2, 3,
or 4 points are specified on the X and Y axes, adjustment is performed for the angle of the coordinate axes
(X-axis and Y-axis tilt) and the distance (line segment length).

Axis adjustment origin point: This is the center point of axial eccentricity. The X and Y axes are tilted from this point.
Point 1: This the reference point used for axis adjustment. For 3-point and 4-point reading, position this point at the
intersection of the X and Y axes of points 2 and 3.
Point 2: Using point 1 as a reference, position this point on the X or Y axis.
Point 3: Using point 1 as a reference, position this point on the X or Y axis.
Point 4: Position this point diagonally opposite point 1, at the intersection of the X and Y axes of points 2 and 3.
