2.3.4 Auto phase gain adjustment
● The gain of the auto phase detection voltage is automatically adjusted.
● Perform this adjustment after confirmation that the periphery of a gutter part within the nozzle
head is not made dirty with ink or the like and the printing head cover is correctly fixed.
● Be sure to perform this adjustment in the case of replacing the boards (EZJ126, 125, 128) or the
nozzle (including the print head) or changing the ink type.
● Perform this adjustment before “Excitation voltage setting”. After setting the optimum
excitation voltage, repeat this adjustment.
● This adjustment is performed when the IJ printer is in a “Drop adjust” or “Standby” state.
