Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a plurality of nozzles for ejecting a liquid;
• a plurality of pressure chambers communicating with the nozzles;
• a plurality of pressure generation elements provided on the plurality of pressure chambers and configured to change volumes of the pressure chambers;
• a plurality of inflow channels connected to the pressure chambers and configured to allow the liquid to enter the pressure chambers;
• a first channel resistance changing section to collectively change channel resistance of each of the inflow channels;
• a pressurizing unit configured to pressurize and supply the liquid to the inflow channels;
• and
• a control unit to control the first channel resistance changing section and the pressure generation elements,
• wherein the control unit repeats control of switching between a first state in which the control unit controls the first channel resistance changing section to collectively increase the channel resistance of the plurality of inflow channels and a second state in which the control unit controls the first channel resistance changing section to collectively make the channel resistance of the plurality of inflow channels smaller than the channel resistance of the plurality of inflow channels in the first state;
• and
• the control unit, with respect to an pressure generation element as the above-mentioned pressure generation element corresponding to an ejection nozzle to eject the liquid among the plurality of nozzles, performs ejection control including extrusion control in which the control unit controls the pressure generation element to reduce the volume of the pressure chamber in the first state, and with respect to a non-pressure generation element as the pressure generation element corresponding to a non-ejection nozzle not to eject the liquid among the plurality of nozzles, the control unit performs non-ejection control including intake and exhaust control in which the control unit controls the non-pressure generation element to expand the volume of the pressure chamber in the first state, and controls the non-pressure generation element to reduce the volume of the pressure chamber in the second state.
