P O I N T
This adjustment should be done as follows.
1. Right end (Home side):
Align the head height on the right and left sides, and also adjust
PG.
2. Middle:
Adjust PG.
3. Left end (Full side):
Adjust PG.
Because the head height on the right and left sides is aligned at the
Home side first, for the adjustment in the middle and on the left
side it is OK to confirm and adjust PG either on the right or left
side of the Printhead.
