Abstract: PROBLEM TO BE SOLVED: To efficiently carry out liquid discharging performance maintenance by reducing discharge defects of a liquid by a liquid discharging head in a liquid discharging performance maintenance method of a liquid discharging apparatus which discharges a liquid from liquid discharging nozzles of the liquid discharging head.
SOLUTION: An ink (predetermined liquid) (i) within a printing head 22 which is supplied from an ink tank 4 to be discharged from the ink discharging nozzle 40a is ejected out of an ink send pipe 159, and bubbles mixed in the ink (i) are removed, whereby the discharge defects of the ink are reduced in the liquid discharging performance maintenance method. A state of the ink (i) in the ink send pipe 159 which ejects the ink (i) within the printing head 22 is detected by a bubble sensor 202. The ink (i) in the printing head 22 is sucked on the basis of the state of the ink (i) by an electrically driven pump 201, whereby bubble removal in the ink (i) is carried out. Hence, the ink discharging performance maintenance is carried out efficiently.

Abstract: PROBLEM TO BE SOLVED: To prevent a liquid in a liquid ejecting nozzle from being dried, thickened and solidified, in a method for maintaining liquid ejection performance of a liquid ejector which ejects the liquid, supplied into a liquid ejecting head from a liquid vessel, from the liquid ejecting nozzle.
SOLUTION: In this method for maintaining the liquid ejection performance, the ink 16 in of the ink ejecting nozzle 10 of the printhead is prevented from being dried, thickened and solidified, in a state wherein ink 16 is supplied from an ink tank and wherein the ink 16 is prevented from spontaneously leaking from the nozzle 10 of a printhead for ejecting the ink 16 from the nozzle 10 formed on a nozzle surface. When the ink is not ejected from the nozzle 10, the pressure of the ink 16 in an ink chamber 14 is changed, and the ink near the nozzle 10 is fluidized. Thus, since the ink 16 near the nozzle 10 is agitated, the drying of the ink 16 can be prevented.
