A liquid reservoir includes: an inflow portion configured to have a liquid flow therethrough; a storage portion configured to store the liquid flowing in through the inflow portion; an outflow portion configured to have the liquid in the storage portion flow out therethrough; a first channel having one end coupled to the outflow portion and the other end opening into the storage portion; a second channel having one end coupled to the outflow portion and the other end opening into the storage portion; and an opening/closing portion configured to open and close the first channel, in which the other end of the first channel opens at a position higher than the other end of the second channel.

Liquid reservoir, liquid ejecting apparatus, and method for controlling liquid ejecting apparatus

A liquid discharge apparatus includes a liquid discharge head, a supply path that supplies a liquid from a liquid supply source to the liquid discharge head, a pump configured to suck and exhaust air, an air suction path in communication with an air suction side of the pump, an air exhaust path in communication with an air exhaust side of the pump, a first storage portion having a portion formed of a flexible wall that is flexible, a first air chamber provided on a side opposite to the first storage portion across the flexible wall and having at least a portion facing the flexible wall and configured to be displaced, and a first switching portion configured to switch a path coupled to the first air chamber between the air suction path and the air exhaust path.

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 filter unit which is detachably mounted on a liquid ejecting apparatus including a liquid ejecting section which ejects liquid, the filter unit including a filter which filters the liquid; and a storage medium which stores information on the filter.

Filter unit and liquid ejecting apparatus

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 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 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.

An ink-jet recording apparatus includes a recording head having a plurality of nozzles through which an ink composition containing an inorganic pigment is ejected, a nozzle surface having nozzle orifices, and a liquid-repellent film disposed on the nozzle surface; an absorbing member that absorbs the ink composition from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member and the nozzle surface relative to each other with a force of 50 to 500 gf. The actuating mechanism moves at least one of the absorbing member and the recording head relative to the other to perform a cleaning operation in which the ink composition is removed from the nozzle surface with the absorbing member. The absorbing member contains an impregnation liquid during the cleaning operation.
