To Manually Adjust the Plotter Calibration
Note: Manual adjustment should only be made if plotting is consistently
shifted in the same direction for all 6 base plate locations. If, for example,
plotting is high in position 1 but low in position 2, manual adjustment will not
help. In this case the plotter bed, or the base plate, is out of tolerance, and
must be corrected.
1. Make a test plot from positions 1, 2, 5, and 6. Type “MMM” in the
markers at each corner of each half of a marker card. There are 8 such
markers on each marker card.
2. Identify each marker card with its base plate position, i.e., 1, 2, 5, 6.
3. Ensure visually that plotting is shifted in the same direction for all base
plate positions.
4. Measure in the X and Y directions from the edge of the marker to the
edge of the printing to determine fow far the plotting is from center.
Use millimeters since this is the units of the calibration function.
5. Click on Plotter under the Options heading, then click on Calibrate.
6. When the Base Plate Calibration Menu appears, select the
appropriate base plate and click on Calibrate.
7. When the Calibrate Origin Menu appears, click on Point 1 to set the
first calibration point.
8. Click the movement arrows to move the pen the amount you calculated
in step 4. You may have to move in the X and Y directions.
Note: Clicking on one of the Step Size boxes will allow you to move the pen in
smaller increments.
9. Once the first point has been manually adjusted, repeat for the second
point by clicking on Point 2.
10. Click the movement arrow to move the pen the amount you calculated
in Step 4. You may have to move in the X and Y directions.
Note: Clicking on one of the Step Size boxes will allow you to move
the pen in smaller increments.
11. Once both points have been manually adjusted, click OK.
12. Repeat Step 1. If marking is centered on the marker, you have
successfully adjusted the calibration. If marking is not centered,
continue with steps 2 through 12.
