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 to lerance show n 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 c learly.
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 variat ion i s la r ge, c lea n t he fluoresce nt sticker and r eplace it if necessary.
