5.3.6 Head Angular Adjustment
During production, slight variations are created in the printhead and
carriage (which is used as a printhead base). If these differences are not
adjusted, they would adversely influence the printhead angle, resulting in
poor print quality.
Head angular adjustment adjusts the head angle against the horizontal
direction by the adjustment lever, and after adjustment is made, you
check the adjustment value by printing the special pattern print. The
following is the adjustment procedure.
1. Select “Head angular adjustment” on the Adjustment menu. The
following screen appears.
Figure 5-8. Head Angular Adjustment
2. Select “Print the head angular adjustment pattern” and click OK. The
following pattern will be printed, but the paper is ejected only far enough
for you to see the pattern.

3. Check the printed pattern. If the series of magenta lines are not printed
directly in the center between the series of black liines, select “Move the
carriage to the adjustment position” and click OK. The carriage moves to
the center so you can manually adjust the head angle.
