Patent ID: 10618276

Abstract:
A liquid ejecting apparatus includes a plurality of nozzles, a plurality of pressure chambers, a plurality of pressure-generation-elements, a plurality of inflow channels, a first-channel-resistance-changing-section, and a control-unit. 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 channel resistance of the inflow channels and a second state in which the control-unit controls the first-channel-resistance-changing-section to collectively decrease the channel resistance of the inflow channels. The control-unit, with respect to a pressure-generation-element corresponding to an ejection nozzle, performs ejection control including extrusion control to reduce the volume of the pressure chamber in the first state, and with respect to a pressure-generation-element corresponding to a non-ejection nozzle, the control-unit performs non-ejection control including intake and exhaust control in which the volume of the pressure chamber is expanded in the first state and is reduced in the second state.
