4.11 Axis Adjustment
When AXIS has been selected for the registration mark mode, axis adjustment is performed manually. If 2, 3,
or4pointsarespecied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.
(1) Select AXIS as the registration mark mode, and then select the number of points for reading. (See Section 4.2,
"Setting the Registration Mark Mode".)
(2) With the plotter in Ready status, press the

Use the [ ] [ ] [ ] [ ] keys to move the pen carriage (the tip of the tool or pen selected by the current
setting) to the position for setting point 1, and then press the
[ENTER] key. If 2-axis adjustment has been performed
previously, the pen carriage will move automatically to the previously set reference point. In this case, use the
[ ] [ ]

(3) The prompts for setting point 2, point 3 and point 4 will be displayed in succession. Make the settings in the same
way as for point 1.
