5.1.1.5 Head Height Adjustment

Head height adjustment is to align the horizontal line of #1 nozzle for each
color in the right head based on the #1 nozzle position for each color in the
left head. Therefore, when either head or both heads are removed or
replaced, it is necessary to perform this adjustment. If this adjustment is
done correctly, color overlapping or white/color line appear.

WARNING
Before starting the head height adjustment,
loosen a screw, which is fixing the right head(for
light colors). Failing to do so does not change
the head position, even though the lever for
head height adjustment is changed.

Please be careful not to forget to loosen the
screw, which is securing the right head. Since it
might be forgotten to do so, especially after the
only left head angular adjustment is performed
in the previous section.

Reason/Background
When replacing the either or both
heads, the nozzle line for horizontal
direction between both heads
becomes incorrect. Therefore, this
head height adjustment is
necessary whenever the heads are
replaced or removed.
The position of head height
adjustment lever is changed by
mistake.
Step1. If the head angular adjustment for right head(for light colors)
is not performed in the previous section 5.1.1.4 "Head
Angular Adjustment", loosen the screw, which is fixing the
right head. (Refer to figure below)
