摘要： A liquid supply apparatus includes: a liquid container; branch paths branching from a path connected to the liquid container, the branch paths being connected to tanks arranged at height positions different from one another and lower than the liquid container; supply valves arranged in the branch paths respectively; and a controller configured to control the supply valves to supply a liquid from the liquid container to each of the tanks. The controller is configured to control the supply valves to temporally separately perform supply of the liquid to tanks of the tanks having a height difference equal to or more than a prescribed value therebetween.

摘要： A liquid discharging apparatus includes: a head having a plurality of nozzles; and a controller. The controller executes: a discharging processing of discharging liquid, from each of the nozzles toward a recording medium, in a liquid droplet amount which is selected for each of pixels from at least three kinds of liquid droplet amounts; and a total discharge amount calculating processing of calculating a total discharge amount of the liquid to be discharged from the nozzles in the discharging processing, based on the liquid droplet amount selected for each of the pixels and a discharge duty which is density of the liquid droplet per a unit area of the recording medium.

摘要： An example printing device includes a plurality of printing agent reservoirs and a printing assembly that is to emit printing agent onto print media. In addition, the printing device includes a pumping assembly fluidly coupled between the plurality of printing agent reservoirs and the printing assembly. The pumping assembly includes a motor and is to transport the printing agent from the plurality of printing agent reservoirs to the printing assembly. Further, the printing device includes a controller coupled to the motor. The controller is to: receive a work parameter of the motor; receive printing agent usage data; and determine that a first printing agent reservoir of the plurality of printing agent reservoirs is empty based on the work parameter and the printing agent usage data.

摘要： In a head body, a head controller inputs individual signals to multiple recording elements that form dots. The individual signals each include a non-waveform signal and a driving waveform signal. The non-waveform signal is input to the recording element during non-driving and the potential thereof is held at a standby potential. The driving waveform signal is input to the recording element during driving, and the potential thereof transitions from the standby potential to one or more displacement potentials. The standby potential of the non-waveform signal input to at least one of the multiple recording elements is different from the standby potential of the non-waveform signal input to at least another one of the multiple recording elements.

摘要： A liquid ejection head in the present disclosure includes a first channel member including a first surface, a plurality of ejection ports in the first surface, a plurality of pressurizing chambers individually communicated with the plurality of ejection ports, and a second surface on the opposite side to the first surface; with a pressurizing member on the second surface; and with a second channel member including a third surface, a fourth surface on the opposite side to the third surface, a raised part which protrudes from the fourth surface, and a first through hole in the raised part. The second channel member is provided on a region in the second surface of the first channel member, in which the pressurizing member is not arranged. When viewed on a plane, an outer circumference of the raised part is located on inner side from an outer circumference of the fourth surface.

摘要： A liquid discharge apparatus includes a conveyance path, a conveyor, and a liquid discharger. The conveyor conveys a medium in a conveyance direction along the conveyance path. The liquid discharger is disposed above the conveyance path to discharge a liquid toward the medium conveyed by the conveyor. The liquid discharger includes a discharge head, a housing, an airflow generator, and slit. The discharge head has a nozzle from which the liquid is discharged. The housing accommodates the discharge head. The housing has a lower face from which the nozzle of the discharge head is exposed and a slit adjacent to the discharge head in the lower face of the housing. The airflow generator generates an airflow flowing through the housing and discharged from the slit toward the conveyance path.

摘要： A liquid ejecting apparatus includes: a liquid ejecting head including an ejecting surface configured to eject a liquid; a tank that reserves the liquid to be supplied to the liquid ejecting head; a circulating mechanism that executes a circulating operation to circulate the liquid between the liquid ejecting head and the tank; and a control unit that controls the circulating mechanism. The control unit executes a recording operation by the liquid ejecting head in a first posture in which the ejecting surface crosses a horizontal plane and executes the circulating operation in a second posture in which an angle made by the ejecting surface and the horizontal plane is smaller than the angle in the first posture.
