5.6 Adjusting the current value (grayscale value)
1. 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 shown below.
R: 90~170 Target: 100
L: 110~130 Target: 100
3. Also check that the current value is 26 mA or less, and the edge of a 0.3 mm nozzle
can be seen clearly.
4. 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 sticker is
joined. If the variation is large, clean the fluorescent sticker and replace it if necessary.
