The pen should make a mark at the center of the cross of the plotter plate
fixture. If this mark is not exactly on center, adjust the Horizontal and Vertical
values until the mark is centered on the crosshairs. (Note: 1 plotter unit = 25
µm = 0.001 inches)
11. Press “Plot Reference Point” to verify calibration
12. Select “Accept” to close the plotter plate calibration window after
calibration
13. Press “Accept” to accept the plotter settings. Verify that all settings are

but adjust the calibration point such that it is off-center of the crosshairs to an extent
to compensate for the off-center dimension.
15. Once the X plot at the center of the 4 corner markers, the system is
calibrated and you are ready to plot on markers.
