  • Patent number: 10449768
    Abstract: A method for driving a liquid ejecting apparatus is provided. The apparatus includes a liquid ejecting head having nozzles in a nozzle surface and being configured to eject a liquid from the nozzles, a wiper being used for wiping the nozzle surface, and a maintenance liquid supply mechanism being configured to supply a maintenance liquid with which it is possible to suppress deterioration of recovery performance of, among the nozzles, a defective nozzle from which the liquid is not ejected properly. The method includes: a first liquid ejection of performing liquid ejecting operation to eject the liquid from the nozzles toward a medium; a wiping of performing wiping operation to wipe the nozzle surface by means of the wiper, with the liquid ejecting operation suspended, and put the maintenance liquid into the nozzles; and a second liquid ejection of resuming the liquid ejecting operation after the wiping.

  • Patent number: 9950510
    Abstract: A liquid ejecting apparatus includes a recording head including a plurality of nozzles from which liquid is ejected, a plurality of pressure chambers which communicate with each nozzle, respectively, a piezoelectric element which causes liquid to be ejected from the nozzle by causing a pressure fluctuation in the liquid in the pressure chamber, and a printer controller which is connected to the piezoelectric element through an individual signal line, and supplies a driving signal which drives the piezoelectric element through the individual signal line. The individual signal line is provided as many as n times (here, n is natural number of 2 or more) or more of the number of pressure chambers.
