 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)
Place the printer on a level, warp-free table. Normal PG 
Adjustment cannot be performed on a warped table.
