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 damper unit includes a damper chamber which has a wall partially composed of a flexible membrane with a rubber elasticity and which is configured to store a liquid; a gas chamber partitioned from the damper chamber by the flexible membrane; a communication portion provided for the gas chamber so that the gas chamber is in communication with an outside of the damper unit; and a one-way valve provided in the communication portion to allow a gas to flow into the gas chamber from the outside of the damper unit and to restrict a gas to flow from the gas chamber to an outside thereof.

Damper unit and liquid ejecting apparatus

An ink jet recording method includes ejecting an ultraviolet-ray curable ink of which a viscosity at 28&#xb0; C. is 8 mPa&#xb7;s or more from a head to a recording medium, and curing the ultraviolet-ray curable ink attached to the recording medium, wherein, in the ejecting of the ultraviolet-ray curable ink, the ultraviolet-ray curable ink is heated such that a temperature of the ejected ultraviolet-ray curable ink becomes 28&#xb0; C. to 40&#xb0; C., and a viscosity of the ultraviolet-ray curable ink at the temperature is 15 mPa&#xb7;s or less.

Ink jet recording method, ultraviolet-ray curable ink, and ink jet recording apparatus

A liquid ejecting apparatus includes: a liquid supply path coupled to a liquid ejection portion to supply a liquid thereto; a liquid discharge path coupled to the liquid ejection portion to discharge the liquid to be supplied thereto; an upstream damper portion which is provided as a part of the liquid supply path and which includes an upstream damper chamber having a wall partially composed of a flexible membrane with a rubber elasticity; and a downstream damper portion which is provided as at least one of a part of the liquid supply path between the upstream damper portion and the liquid ejection portion and a part of the liquid discharge path and which has a flexible wall composed of a resin film.

Liquid ejecting apparatus

A liquid ejecting apparatus includes: a pump which is provided for a liquid supply path to supply a liquid stored in a liquid storage portion to a liquid ejection portion; a filter portion which is provided between the pump and the liquid ejection portion as a part of the liquid supply path and which includes a filter and a filter chamber defined by the filter into an upstream filter chamber and a downstream filter chamber; a return path coupled to the upstream filter chamber and the liquid storage portion; and a discharge valve located at the return path. While the pump is driven in a non-communication state between the upstream filter chamber and the liquid storage portion, the non-communication state is switched to a communication state therebetween through the return path using the discharge valve.

Liquid ejecting apparatus and maintenance method thereof

Provided is a liquid injecting apparatus equipped with a liquid injecting head, which is mounted on a carriage and moved reciprocally in a widthwise direction of a target, and a valve unit, which is mounted on the carriage to be supplied with liquid via a supply passage from a liquid retainer and to supply liquid to the liquid injecting head. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve.

A liquid ejecting apparatus includes: a hollow housing with an aperture; a liquid ejecting head; and a supply mechanism. The liquid ejecting head has a nozzle through which liquid is to be discharged. The liquid ejecting head is supported in the housing with the nozzle exposed through the aperture. A gap is reserved between the liquid ejecting head and an inner circumferential surface of the aperture. The supply mechanism supplies dry gas to an inner space of the housing.

Liquid ejecting apparatus and method of operating liquid ejecting apparatus

A printing apparatus includes: a head including a nozzle disposed on a nozzle surface and configured to discharge ultraviolet-curable ink onto a recording medium; first and second irradiation units as an ultraviolet irradiation unit configured to irradiate the ultraviolet-curable ink discharged onto the recording medium with an ultraviolet ray; and a smoke supply unit configured to supply smoke to a part of an advancing path from the first and second irradiation units to the nozzle surface of an ultraviolet ray irradiated from the first and second irradiation units and entering the nozzle surface.

Printing apparatus and printing method

Valve unit and liquid ejecting apparatus

An ink jet apparatus includes a head, a circuit substrate, a cover frame, a heat sink, a fan, and a wall section. The cover frame supports the circuit substrate that has a drive circuit that drives the head inside of the cover frame and has a through hole. The heat sink that dissipates heat generated in the circuit substrate is disposed inside of the cover frame and has a part that is in direct or indirect contact with the circuit substrate. The fan generates air flow and is arranged such that the fan and the heat sink face to each other via the through hole. The wall section is disposed inside of the cover frame such that the air flow is not directly blown against the drive circuit and the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.

Ink jet apparatus

A printing apparatus includes: an ejection head that prints an image on a recording medium supported by a support member by ejecting liquid from a nozzle formed in a portion facing the support member; and an irradiation section that includes a housing which is open toward the support member, and a light emitting section housed in the housing and emitting light to cure the liquid, the irradiation section being configured such that light emitted from the light emitting section is irradiated onto the recording medium supported by the support member via the opening, wherein the housing includes an inclined section which extends from the opening toward the ejection head such that a distance from the inclined section to the support member decreases toward the ejection head, and the inclined section is provided so that &#x3b8;is established.
