Liquid container

A liquid supply device includes a connection body which includes a liquid introduction portion which is capable of connecting to a liquid outlet portion of a liquid container which includes the liquid outlet portion which contains the liquid which is supplied to the liquid ejecting unit which ejects the liquid and is capable of guiding out the liquid, a liquid container support portion which is capable of supporting the liquid container in a state in which the liquid introduction portion is capable of being connected to the liquid outlet portion to be capable of being freely attached and detached, and a connection body holding portion which holds the connection body in a state in which a connection of the liquid introduction portion with the liquid outlet portion is released.

Liquid supply device and liquid ejecting apparatus

A liquid ejecting apparatus includes a medium support portion that has a medium support surface for supporting a medium, a liquid ejecting unit that ejects liquid onto the medium supported on the medium support surface through a plurality of nozzles arranged in a nozzle surface, a first cleaning member that wipes the nozzle surface by moving relative to the liquid ejecting unit in a direction along the nozzle surface in a first maintenance operation of discharging the liquid through the nozzles for maintenance of the liquid ejecting unit, and a second cleaning member that removes foreign matters which have adhered to the nozzle surface by moving relative to the liquid ejecting unit in the direction along the nozzle surface in a second maintenance operation of removing the foreign matters.

Liquid ejecting apparatus and liquid ejecting apparatus maintenance method

There are provided a head ejecting a liquid, a retaining section retaining the liquid, a degassing section with a degassing unit, a first supply flow path flowing the liquid from the retaining section to the degassing section, and a second supply flow path flowing the liquid degassed in the degassing section to the head. The degassing section further includes a degassing flow path having the degassing unit to flow the liquid while reducing pressure, a bypass flow path flowing the liquid without reducing the pressure, a branching section dividing the liquid flowing in the first supply flow path into the degassing flow path and the bypass flow path, and a joining section joining the liquid flowing in the degassing flow path and the liquid flowing in the bypass flow path to flow in the second supply flow path.

Liquid ejecting apparatus and liquid supply method

A liquid ejecting apparatus includes a plurality of nozzles which eject liquid; a common liquid chamber which supplies liquid to the plurality of nozzles; a liquid flow path for supplying liquid which is accommodated in a liquid accommodation unit to the common liquid chamber; a deaeration unit which deaerates liquid in the liquid flow path; a liquid flow unit which causes liquid in the liquid flow path to flow; a return flow path which connects the common liquid chamber and the liquid accommodation unit; and an on-off valve which closes the return flow path by being in a closed state.

Liquid ejecting apparatus

A liquid discharge apparatus includes a head configured and arranged to discharge a liquid including a sedimentary substance, and a liquid supply path configured and arranged to supply the liquid from a liquid tank where the liquid is retained to the head. The liquid supply path has a region with differences in elevation of a predetermined length or more in a vertical direction. The liquid supply path has at least one convex section formed by folding at each of one side and another side in a direction which intersects the vertical direction in the region.

Liquid discharge apparatus

A liquid discharge apparatus includes a head configured and arranged to discharge a liquid including a sedimentary substance, and a liquid supply path for supplying the liquid from a liquid tank where the liquid is retained to the head. The liquid supply path has differences in elevation of a predetermined length or more in a vertical direction. The liquid supply path has a portion formed into a stepped shape and an angle formed by a width portion and a height portion in the portion formed into the stepped shape is 45 degrees or more and 90 degrees or less.

A liquid discharging apparatus, which discharges liquid from a nozzle of a liquid discharging head on the basis of data, includes a controller and a member. When the controller is in a standby state where the liquid is not discharged from the nozzle on the basis of the data or after the controller has received a power OFF instruction, the controller performs a drawing operation in which the liquid is drawn to a side opposite to a discharge direction in which the liquid is discharged so as to at least form a space at a distal end portion of the nozzle. After the controller has performed the drawing operation, the member covers an opening of the nozzle.

Liquid discharging apparatus and method of discharging liquid

An ink jet recording apparatus includes an ejection head which ejects an aqueous ink composition containing a resin component, a water-soluble organic solvent having a boiling point of 250&#xb0; C. or less, a surfactant, and water; a first cap device which covers and moisturizes the ejection head; and a first maintenance liquid supply device which supplies a maintenance liquid to the first cap device. The maintenance liquid contains water and at least one water-soluble organic solvent of alkanediols having a boiling point of 250&#xb0; C. or less and alkylene glycol monoether derivatives having a boiling point of 250&#xb0; C. or less.

Ink jet recording apparatus and maintenance liquid for ink jet recording apparatus

An electrical circuit substrate, a first holding member holding the electrical circuit substrate, a head configured to discharge liquid, a flow path member having a flow path in which flows the liquid supplied to the head, and a second holding member holding the head and the flow path member are provided. The first holding member and the second holding member are detachably attached with each other.

Head unit having electrical circuit substrate and image recording device including head unit

A liquid discharge apparatus includes an ink tank configured and arranged to retain a plurality of types of ink including sedimentary ink, a head configured and arranged to discharges the ink, and an ink supply path section configured and arranged to supply the ink from the ink tank to the head.
