 Before starting PG adjustment, completely wipe drops of
ink around the Print Head. Remaining drops of ink will
stick to the continuity measurement portion of the
Adjustment Gauge, and generate continuity before the
continuity measurement portion makes contact with the
metal frame around the Print Head, interrupting accurate
PG Adjustment.
 As the ink in the Print Head may stick fast and damage
the Print Head during PG Adjustment, make the
continuity time detected with a tester as short as
possible. (Maximum 3 minutes)
