Abstract

PURPOSE:To prevent a nozzle from being clogged with an ink by a method wherein the pressure at which the ink is supplied to the nozzle is set to be higher at the starting of a jetting operation than in normal supplying condition, and the pressure is changed over to a normal supplying pressure when the jetting operation is finished. CONSTITUTION:Normally, the ink contained in an ink tank is fed to an ink chamber 2 through a filter 6, an accumulator 5 and a filter 4 by an ink feed pump 7 and is jetted from the nozzle 1 by the function of a piezoelectric element 3. Thereafter, when restarting the jetting operation, a high-pressure pump 9 is operated with a change-over cock 10 suitably changed over to apply a high pressure to the ink, and the ink is jetted together with the solid portion adhered to the tip part of the nozzle 1. Then, the cock 10 is returned to its original position and the operation of the high-pressure pump 9 is replaced by the normal operation of the ink feed pump 7.
