A liquid ejecting apparatus includes a liquid ejector that ejects a liquid from a nozzle, a wiping mechanism that wipes a nozzle surface on which a plurality of nozzles is disposed with a wiping member, and a wiping-liquid supply mechanism that supplies a wiping liquid to the wiping member. The liquid ejecting apparatus is configured to perform wet-wiping of wiping the nozzle surface in a state where the wiping member has absorbed the wiping liquid and is configured to change a supply amount of the wiping liquid when the wiping member wipes the nozzle surface.

Liquid ejecting apparatus and maintenance method of liquid ejecting apparatus

A cap device is designed to form a space surrounding an opening of a nozzle of a liquid ejecting head when the cap device is in contact with the liquid ejecting head including the nozzle for ejecting a liquid, and includes a moisturizing chamber to which a moisturizing fluid for moisturizing the above space is supplied, and a partition wall having gas permeability and configured to partition the space and the moisturizing chamber, where part of the partition wall is formed of a flexible portion.

Cap device and liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head having nozzles for ejecting a liquid, and an attachment section to which a maintenance unit to be used for maintenance of the liquid ejecting head is to be detachably attached. If the maintenance unit having a maintenance mechanism for performing the maintenance by driving force transmitted from the attachment section is a first unit and the maintenance unit having no maintenance mechanism is a second unit, one of a plurality of the maintenance units including the first unit and the second unit and having different structure is interchangeably attached to the attachment section, and the attachment section includes an identification section configured to identify the structure of the attached maintenance unit and a driving-force transmission section configured to transmit the driving force to the attached first unit.

Liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head including a nozzle which ejects liquid, and an opening face to which the nozzle opens; a cap which forms a closed space between the cap and the opening face; and a holder which holds the cap so as to move in a tilting manner in a direction which goes along the opening face.

First, second, and third ink absorbing bodies are accommodated in a container of a recovery reservoir in this order from the side corresponding to a bottom surface of the container, so that an introduction chamber is defined in the middle of a recovery space. A lid having a shutter plate and a communication hole is located over the third ink absorbing body. The upper side of the introduction chamber is covered by the shutter plate to suppress volatilization of solvent element of waste ink introduced into the introduction chamber. In addition, the communication hole is located in a portion of the upper surface of the third ink absorbing body, so that solvent element of ink absorbed by the third ink absorption body volatilizes.

Liquid recovery containers and liquid ejection apparatus

A waste liquid container includes a fitted portion, in which a discharge unit is fittable in a removable manner, a container connection terminal, which contacts a device connection terminal, an insertion restriction portion, which contacts a device contact portion and restricts movement of the waste liquid container in the insertion direction, and an engaged portion, which includes a contacted portion that contacts a removal restriction unit and restricts movement of the waste liquid container in the removal direction. The engaged portion is located toward an inner side in the lateral direction from a side wall at a position lower than both of the container connection terminal and the insertion restriction portion. The removal restriction unit is receivable in a region located toward an outer side in the lateral direction from the engaged portion.

Waste liquid container, liquid ejection device, and waste liquid collection system

A waste liquid container that can be installed to a waste liquid discharging device main body. The waste liquid container includes an insertion hole into which a waste liquid discharging nozzle, which is included in the waste liquid discharging device main body, having a large diameter portion and a small diameter portion located on a front end side relative to the large diameter portion is inserted. When the waste liquid container is installed to the waste liquid discharging device main body, the insertion hole guides the small diameter portion by being brought into contact with an outer circumferential face of the small diameter portion in an inner face of the insertion hole and determines a position of the waste liquid container in a diameter direction of the large diameter portion with respect to the waste liquid discharging device main body by being fitted with the large diameter portion.

Waste liquid container and waste liquid discharging device

In a waste liquid container which is attachable and detachable to a recording portion including a liquid ejecting head which discharges a waste liquid and can store the waste liquid which is discharged from the liquid ejecting head in a state of being mounted on the recording portion, an engagement portion which protrudes from a side wall of the waste liquid container and is disposed lower in a vertical direction than a guide portion which is provided on the recording portion in the state of being mounted on the recording portion is provided.

Waste liquid container and liquid consumption apparatus

A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.

Liquid ejecting apparatus and maintenance method for a liquid ejecting apparatus

A liquid ejecting apparatus includes a recording head ejecting ink onto a paper; a tray which moves in a direction along a nozzle forming surface in a state where a plurality of units are displaceably supported in a direction approaching and separating from the nozzle forming surface of the recording head; and a cam which is disposed on a moving path of the tray and engages individually with at least two units while the tray moves in a direction along the nozzle forming surface, and makes the units engage individually to be displaced in the direction approaching and separating from the nozzle forming surface.

In a waste liquid container which is detachably mounted on a waste liquid container mounting portion including a device side connection terminal and a plate spring, the waste liquid container includes a waste liquid storing chamber which stores waste liquid, a first wall portion and a second wall portion which are disposed so as to face each other with the waste liquid storing chamber interposed therebetween, a container side connection terminal which is provided on an outer surface of the second wall portion and contacts the device side connection terminal at the time of being mounted on the waste liquid container mounting portion, and a positioning protrusion of the plate spring which is provided on the first wall portion so as to receive a biasing force which is applied from the first wall portion side toward the second wall portion side.
