Provided is a management apparatus includes: an acquisition unit acquiring remaining-quantity information indicating a remaining quantity of a consumable included in the image forming apparatus; a database storing the remaining-quantity information and image forming apparatus identification information in association with each other, and storing user identification information and a usage history of the image forming apparatus by the user in association with each other; a calculation unit reading the usage history from the database based on externally-designated user identification information, calculating a predicted usage quantity of the consumable in an image forming apparatus having externally-designated apparatus identification information based on the read usage history, reading the remaining-quantity information from the database based on the externally-designated apparatus identification information, generating required information on the consumable based on the read remaining-quantity information and the calculated predicted usage quantity; and a notification unit notifying the required information generated by the calculation unit.

Management apparatus, method, and medium for deciding how many ink tanks a user should carry based on usage information

There are provided a liquid ejection apparatus with low costs, a liquid container, and a manufacturing method thereof. To this end, a rocking body is assembled to the liquid container to suppress the drop thereof by melting and swaging of a support shaft.

Liquid ejection apparatus, liquid container, and manufacturing method thereof

The liquid storage container of the present invention includes a liquid storage chamber, a support part, and a rocking body configured to rock with the support part as a fulcrum. The rocking body has, on one hand, a float part that moves in accordance with the height of the liquid surface of the liquid within the liquid storage chamber, and on the other hand, a detection target part that is used to detect the amount of the liquid within the liquid storage chamber, and the detection target part is coupled to the supported part via an arm part. The low end in the vertical direction of a connection part at which the arm part and the supported part are connected is located on the lower side in the vertical direction than the top end in the vertical direction of a rotating area of the supported part.

Liquid storage container and printing apparatus

There are provided a liquid ejecting device stably containing liquid inside a liquid containing unit, a head, and a liquid filling method. The liquid ejecting device includes a liquid container that can store liquid thereinside, a head including a liquid containing unit that has a holding member capable of holding liquid thereinside and a liquid ejecting unit that ejects liquid, and a flexible member that connects the liquid container to the liquid containing unit and supplies the liquid stored inside the liquid container to the liquid containing unit, and an internal space of the liquid containing unit has a rectangular parallelepiped shape, and a value obtained by dividing a length of a long side of a cross-section along a horizontal surface in the internal space by a length of the holding member along a gravity direction is 1.5 or more in a posture having the head provided on the carriage.

Liquid ejecting device, head, and liquid filling method

A liquid container can be mounted to an apparatus in which an optical sensor is installed. The liquid container has a reservoir storing a liquid, a detection chamber communicates with the reservoir and a displacement member displacing according to an amount of liquid stored in the reservoir. The displacement member has a light shielding part that moves in a first direction between a position where light of the optical sensor is shielded and a position where the light is not shielded and a regulating member regulating movement of the displacement member in a direction crossing the first direction. An inner wall of the detection chamber has a first area facing the light shielding part and transmitting the light of the optical sensor and a second area facing the regulating member. The first area and the second area are connected via a ridgeline having an inter-surface angle larger than 180 degrees.

Liquid container and liquid residue detection apparatus

An inkjet head includes a discharge element substrate including a base material provided with an energy generation element for generating energy to be used for discharging ink, a discharge port provided corresponding to the energy generation element, and an electrode pad electrically connected to the energy generation element, an electric contact substrate including an electric contact terminal for receiving an electric signal from an inkjet apparatus, and an electric wiring tape for electrically connecting the electric contact substrate and the discharge element substrate to each other, wherein a sealing member sealing a vicinity of an electric connection portion between the electric contact substrate and the electric wiring tape is a cured product of a composition including a silicone-modified resin, a boron trifluoride compound, and a mercaptosilane compound.
