  • Patent number: 10906314
    Abstract: A liquid ejecting apparatus includes: a liquid ejecting head including a plurality of nozzles for discharging liquid and a supply passage through which the liquid to be supplied to the plurality of nozzles flows. The nozzles are arranged in a line; one of the nozzles at a first end of the line being a first end nozzle, whereas one of the nozzles at a second end of the line being a second end nozzle. A height of the first end nozzle is set to be greater than a height of the second end nozzle. The liquid flows through the supply passage in a direction from the first end nozzle to the second end nozzle.

  • Patent number: 10618289
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head provided with a nozzle and a cap that executes capping for forming a first space to which the nozzle is open, in a surrounding manner. The cap includes a capping member that is provided with a suction hole and an atmosphere communicating hole which is configured to allow an inside of the cap to communicate with an outside, a liquid absorber that is disposed inside the capping member, and a reception member that is disposed inside the capping member so as to form a second space between the liquid absorber and the reception member. The second space is positioned closer to a side of the liquid ejecting head than to the liquid absorber in a posture of capping, and the atmosphere communicating hole is open to the second space.
