METHOD FOR DRIVING LIQUID JET HEAD, AND DRIVING SIGNAL GENERATOR FOR LIQUID JET HEAD

摘要

PROBLEM TO BE SOLVED: To make a jetted liquid minute when jetting the liquid that contains a polymer.;SOLUTION: This method for driving a liquid jet head for jetting the liquid that contains the polymer by applying voltage to the liquid jet head includes building up the voltage from a first voltage to a second voltage, building up the voltage from the second voltage to a third voltage at a gradient steeper than a gradient when building up the voltage from the first voltage to the second voltage, holding the third voltage, dropping the voltage from the third voltage to a fourth voltage, holding the fourth voltage, building up the voltage from the fourth voltage to a fifth voltage, holding the fifth voltage, dropping the voltage from the fifth voltage to a sixth voltage, holding the sixth voltage, and building up the voltage from the sixth voltage to a seventh voltage, wherein a gradient when building up the voltage from the fourth voltage to the fifth voltage is gentler than the gradient when building up the voltage from the second voltage to the third voltage.;COPYRIGHT: (C)2013,JPO&INPIT
