Abstract

PURPOSE:To stabilize the ink jet by a method wherein the impressed voltage of an electromagnetic valve is kept high for a certain period of time and thereby the temperature of the valve is maintained at the saturated level in an ink jet printer of a type of device wherein the ink supplied to a nozzle is controlled by the electromagnetic valve. CONSTITUTION:An electromagnetic valve 5, controlling the supply of ink to an ink jet nozzle 6, interrupts the flow route of ink by a plunger 11 until the pressure of ink from an air chamber 4 reaches a fixed level. When the rated voltage is impressed continuously on the electromagnetic valve 5, the temperature of the valve 5 rises as shown by B and, the property of ink is changed, and a displacement occurs in printing dots. However, when the voltage Emax near the maximum rated voltage is impressed on the valve 5 to raise the temperature of the valve 5 forcibly and promptly up to the saturated level as shown by B' and, after that, the voltage is returned to the rated or the holding voltage E, the temperature of the electromagnetic valve 5 is kept thereafter at a fixed level, thereby the influence on a printed picture within a sheet of copy is eliminated.
