Print Head Alignment

If lines are misaligned or print results are grainy,
perform Print Head Alignment.
The print head fires ink when moving to the left and to
the right while printing. Since there is a short distance
(gap) between the paper surface and the print head, a
print misalignment may occur due to the paper
thickness, changes in temperature or humidity, and
internal inertia while the print head moves.
Select from Uni-D Alignment or Bi-D Alignment.
