An inkjet printer includes an inkjet head configured to discharge ink and an ink tank including a plurality of ink storage portions in which the ink is stored to supply the ink to the inkjet head via a connected tube, and replenishing ports via which the plurality of ink storage portions is replenished with ink, wherein the ink tank has an outer wall facing an outer side of the ink tank and having a thickness greater than a thickness of a partition wall arranged between the plurality of ink storage portions.

Inkjet printer

A liquid replenishing system includes a liquid tank and a liquid storage bottle for storing liquid to be replenished to the liquid tank. The liquid tank includes a tank body, a cylindrical adapter, and a needle penetrating into the tank body inside the cylindrical adapter. One end of the needle is located outside the tank body and another end of the needle is located inside the tank body. The liquid storage bottle includes a bottle body, a nozzle having an ejection port for ejecting a liquid stored in the bottle body, and includes a slit valve provided at the ejection port. In a case where the nozzle of the liquid storage bottle and the cylindrical adapter of the liquid tank are fitted to each other, one end of the needle is inserted into the slit valve so that the liquid storage bottle is secured to the liquid tank.

Liquid replenishing system

To provide a liquid storage container equipped with a plug member that can prevent leakage of a liquid from the liquid storage container and can be opened without causing scatter of the liquid, and a liquid ejection apparatus equipped with the liquid storage container. For the purpose, at least one of a connection part of the convex part with the cover part and an apical part of the convex part most apart from the connection part is provided offset from the centroid of the cover part, seen from a direction orthogonal to an opening surface of a supply port in a state that the plug member is mounted on a supply port of the liquid storage container.

Liquid storage container and liquid ejection apparatus

A printer system connects a plurality of printers and a terminal via a network. First, the system inputs data for a new print from the terminal. Next, based on the inputted data, the system uses a learned model that has learned to select one printer among the plurality of printers based on data that was used in previous printing by the plurality of printers, to infer a printer suited to the new print from the plurality of printers. As a result of the inference, the system conveys the obtained printer to the terminal.

Print system including a learned model to select a printer

A liquid ejection apparatus includes: a liquid ejection unit; a liquid storage container including a replenishment port through which to replenish the liquid storage container with a liquid and an opening-closing member which closes and opens the replenishment port; and a notification unit configured to notify a user of information to be recognized by the user; and a control unit configured to control the notification unit. In a case where the time elapsed since the previous liquid ejection by the liquid ejection unit is a predetermined time or longer, the control unit causes the notification unit to notify the user of information on replenishment of the liquid storage container with a liquid.

Liquid ejection apparatus and method of controlling liquid ejection apparatus

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

Liquid container unit and recording apparatus

There are provided a liquid container including a plug member which prevents leakage of a liquid from the liquid container and can be opened without scattering the liquid and a liquid ejection apparatus including the liquid container. For that purpose, a projecting portion in the plug member is provided below a center part of the plug member in a gravity direction in an attitude at the time of use of the liquid ejection apparatus.

Liquid container and liquid ejection apparatus

A liquid supplying mechanism includes: a tank including a liquid storage section configured to store a liquid, and a liquid injection port configured to inject the liquid into the liquid storage section; and a bottle configured to replenish the liquid into the tank. The bottle includes: a bottle section configured to store the liquid; and a protruding section, which protrudes from the bottle section, and is insertable into the liquid injection port so as to inject, into the liquid storage section, the liquid stored in the bottle section. The liquid injection port includes: a protruding section insertion portion into which the protruding section of the bottle is insertable; and a protruding section fixing portion, which is engageable with the protruding section of the bottle, to thereby be capable of fixing the bottle to the tank.

Liquid supplying mechanism, and liquid ejection apparatus

An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.
