Adjusting the current value (grayscale value)
1. Remove the jigs. Press the lower button to display the current and grayscale values.
2. Rotate the R-axis by hand to find the positions where the grayscale values (GR and
GL) are maximized and minimized. Check that the minimum and maximum grayscale
values are within the tolerance of 95~250. Also check that the current value is 24 mA
or less.
3. If the grayscale values are not within the target values, adjust them as shown below.
4. Press the lower button to display “CURRENT UP”. If the grayscale value is lower than
the target value of 120, press the lower button to raise it. If the current value is higher
than 20 mA, press the upper button to display “CURRENT DOWN”. Press the lower
button until the current value is within tolerance.
5. Rotate the R-axis through one full rotation and confirm that there is no position where
the variation in the grayscale values (GR and GL) is extreme. Pay particular attention
to the variation in grayscale values at the position where the fluorescent seal is joined.
If the variation is large, clean the fluorescent sticker and replace it if necessary.
