A liquid ejecting apparatus includes a liquid ejecting head which ejects a liquid from a plurality of nozzles disposed on a nozzle surface; an absorbing member which makes contact with the nozzle surface and can absorb a liquid which is adhered to the nozzle surface; and a pressing member which causes the ink absorbing member to contact the nozzle surface by pressing the absorbing member from a side which opposes a side which contacts the nozzle surface. In the liquid ejecting apparatus, a pressure applied to a nozzle peripheral region within the nozzle surface due to the absorbing member which is pressed by the pressing member making contact with the nozzle surface is smaller than a pressure applied to a region other than the nozzle peripheral region within the nozzle surface.

Liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid from a plurality of nozzles disposed in a nozzle surface, a wiping member that wipes the nozzle surface, and a wiping member moving mechanism that moves the wiping member between a wiping position where the nozzle surface is wiped and a retracted position. The wiping member moving mechanism has a wiping member holding mechanism that holds the wiping member and a holding state releasing mechanism that releases a holding state of the wiping member holding mechanism in a case where a load that is equal to or higher than a set value is received.

Liquid ejecting apparatus and maintenance device

A liquid ejecting apparatus includes a liquid ejector that ejects a liquid, a liquid supply flow path that connects a liquid supply source and the liquid ejector, a plurality of branch flow paths provided in the liquid supply flow path, filters that are disposed separately in each of the branch flow paths, and a flow path opening/closing mechanism that opens and closes the branch flow paths.

Method of discharging fluid in a liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid container containing section, and a pressurizing section that pressurizes inside of the liquid container containing section. The liquid container containing section has a casing that contains a liquid container, a mounting member that is mounted with the liquid container, and a cover that covers an opening that is formed in the casing, the mounting member is arranged inside the casing on the opening side, the cover is arranged outside the casing on the opening side, and the mounting member is fixed to the cover.

Liquid ejecting apparatus and liquid supplying apparatus

A liquid container is configured to be placeable in a containing vessel having a pressurized space and a vessel-side liquid supply structure that is connected with a liquid consuming device. The liquid container comprises a liquid container body; a liquid supply structure that is configured to supply a liquid contained in the liquid container body to the vessel-side liquid supply structure; a container body holding assembly that is configured to hold the liquid container body; and a substrate holding structure that is provided in the container body holding assembly. The container body holding assembly is positioned relative to the containing vessel such that the liquid container body and the liquid supply structure are placed inside of the pressurized space and the substrate holding structure is placed outside of the pressurized space.

Liquid container

A maintenance unit mounted in a removable manner in a liquid ejector that ejects liquid. The maintenance unit includes an elongated maintenance member, which is used to perform maintenance on the liquid ejector, and a memory, which is configured to store information related to the maintenance member.

Maintenance unit and liquid ejection device

A liquid container is configured to be detachably attached to a liquid container containing section in a liquid ejecting apparatus that includes the liquid container containing section, a supply flow path that supplies liquid from a liquid supply section that is provided in the liquid container containing section to a liquid ejecting section, and an opening and closing section that opens and closes the supply flow path. The liquid container includes an operation section configured to switch an opening and closing state of the opening and closing section by working together with an attaching and detaching operation with regard to the liquid container containing section.

Liquid container, adapter, and liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting portion provided with a nozzle opening area in which a plurality of nozzles ejecting liquid onto a medium are open; and a wiping portion that wipes the nozzle opening area in a first direction and a second direction opposite to the first direction, in which the nozzle opening area includes a first wiping target area and a second wiping target area which are at different positions in a direction intersecting with the first direction, and the wiping portion wipes the first wiping target area in the first direction, and wipes the second wiping target area in the second direction.

A liquid supply system includes a common mounting portion into which a first liquid storage body capable of storing a liquid and a substitute mounting body which is connected to a second liquid storage body capable of storing a liquid can be exchangeably mounted, a mounting target detection unit capable of detecting whether or not the first liquid storage body and the substitute mounting body are mounted to the common mounting portion, a pressurization supply unit which supplies the liquid which is stored in the second liquid storage body to the substitute mounting body under pressure, and a control unit which drives the pressure supply unit when a plurality of control conditions are satisfied.

Liquid supply system, liquid ejecting apparatus, and liquid supply method

A liquid container is configured to be detachably attached to a liquid container storage section arranged at an incline such that a liquid supply section is a lower side in a direction of gravity. The liquid container includes a liquid container-side positioning section with which a mounting member-side engagement section provided to the liquid container storage section is engageable, and a liquid lead-out section to which the liquid supply section is connected. The liquid container-side positioning section and the mounting member-side engagement section are engaged before the liquid lead-out section and the liquid supply section are connected when the liquid container is mounted onto the liquid container storage section.

A liquid container is configured to be detachably attached to a liquid container storage section having a liquid supply section, and a damping section including a movement section that seals off one end of a recess space and is movable in a direction of compression in which air of the recess space is compressed, and an urging section that urges the movement section in a direction opposite to the direction of compression. The liquid container includes a liquid lead-out section configured to be connected to the liquid supply section, and an abutment section arranged on a same side as a side section to which the liquid lead-out section is provided, and abuttable against the movement section in a direction of mounting that matches the direction of compression when the liquid container moves in the direction of mounting with respect to the liquid container storage section.

Liquid container, adapter, and liquid ejection apparatus

A wiper cassette includes a long wiping member which wipes a liquid adhered to a liquid ejecting head which ejects the liquid; a feed roller around which an end of the wiping member is wound in a longitudinal direction; and a winding roller around which other end of the wiping member is wound in the longitudinal direction, and the wiper cassette is mounted so as to be freely detachable and attachable into a wiper holder. Furthermore, the wiper cassette further includes a winding gear supported by the winding roller; and a power point acting portion on which a load acts in a removal direction when the wiper cassette is removed from the wiper holder, in which the power point acting portion is positioned closer to the removal direction side than the winding gear in a mounted state in which the wiper cassette is mounted into the wiper holder.
