Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting apparatus includes a forming section which forms an image on a medium, a transport section which transports the medium in a first direction, and a heating section which heats a transport path on which the medium is transported, in which the forming section includes a first forming section which forms a pre-treatment liquid layer that includes a thermosetting resin on the medium, a liquid ejecting head which forms an image layer on the medium by ejecting liquid, and a second forming section which forms a post-treatment liquid layer that includes a thermosetting resin and is different from the pre-treatment liquid layer on the medium, and B&#x3c;A and B&#x3c;C in a case where content of the thermosetting resin in the pre-treatment liquid is A, content of the thermosetting resin in the liquid is B, and content of the thermosetting resin in the post-treatment liquid is C.

Liquid ejecting apparatus

A liquid ejecting head includes a driving element for ejecting a liquid from a nozzle; a wiring electrically connected to the driving element; an accommodation space that accommodates at least a portion of the wiring; and dummy wirings which are arranged in the accommodation space and adsorb sulfur.

A liquid ejecting apparatus includes a liquid ejecting unit which can eject liquid from a nozzle; a supply flow path through which liquid is supplied to the nozzle; a pressure adjusting unit which includes a pressure chamber which can store liquid; a storage chamber at least a part of which is formed by a gas permeable unit, and which stores liquid; a connection flow path which connects a space including a flow path portion from the pressure chamber to the nozzle and the pressure chamber, and the storage chamber; an opening-closing valve which can switch a communicating state between the space and the storage chamber through the connection flow path; and a pressurizing unit which pressurizes the storage chamber when the opening-closing valve is in the closed state.

A liquid holding container includes a liquid accommodating chamber, a flow path, and a filter. The liquid accommodating chamber is configured and arranged to hold liquid. The flow path is communicated with the liquid accommodating chamber via a first through hole and a second through hole. The filter is disposed in the flow path. The first through hole and the second through hole are each communicated with the flow path.

Liquid holding container

A liquid ejecting apparatus includes: a liquid ejecting unit that ejects a liquid supplied through a liquid supply path from a nozzle; a maintenance unit that performs a maintenance operation of the liquid ejecting unit; and an ejection state detecting unit that is able to detect a state inside a pressure chamber communicating with the nozzle. The ejection state detecting unit detects a state inside the pressure chamber before the maintenance operation and at least one state inside the pressure chamber during the maintenance operation or after the maintenance operation, and is able to determine malfunction of at least one of the maintenance unit and function units arranged in the liquid supply path based on a change in a state inside the pressure chamber due to the maintenance operation.

Provided is an air jet emission method used in a recording apparatus. The recording apparatus performs predetermined printing by ejecting ink droplets from a recording head provided in an apparatus body onto a medium. The medium is fed into the apparatus body while being guided by a guide and is transported from an upstream side, which is one side with respect to the apparatus body, toward a downstream side, which is an opposite side with respect to the apparatus body. The air jet emission method comprises: emitting a jet of air onto a surface of the transported medium at a predetermined area over a heating device at the upstream side, thereby blowing dust off the surface of the transported medium. The heating device is provided in the guide so as to apply heat to the transported medium.

Air jet emission method used in liquid ejecting apparatus, and the apparatus

A liquid ejecting apparatus comprises: a supply passage through which liquid is supplied from a liquid supply source to a liquid ejecting unit; a filter housing portion provided in the supply passage, a first filter being provided inside the filter housing portion; a circulation passage forming portion, one end of which is connected to a space portion located closer to the liquid supply source than the first filter is, the other end of which is connected on the supply passage to a position closer to the liquid supply source than the first filter is, thereby forming a circulation passage; a foreign object separation unit that works with a flow pump, which is a pump for circulation of the liquid through the circulation passage, to cause a foreign object to come off from the first filter; and a second filter that is detachably provided on the circulation passage.

Provided is a maintenance unit that is detachably attached to a liquid ejecting apparatus including a liquid ejecting section for ejecting liquid, the maintenance unit including: a maintenance section that is used for maintenance of the liquid ejecting section; and a recording target section in which information related to the maintenance section is recorded by the liquid that is ejected by the liquid ejecting section in a visibly recognizable manner.

Maintenance unit and liquid ejecting apparatus

A liquid ejecting head includes a fixing plate which includes a bottom surface which is fixed onto the nozzle surface of each of a plurality of head units which are provided to line up in a state in which a first gap is formed along a first direction, and a first side surface which extends from an edge of the bottom surface which is positioned closer to an outside in the first direction than the lined-up head units to the head unit side. The fixing plate includes a second gap which is formed between the first side surface and the head units which are positioned at ends in the first direction among the head units. The liquid ejecting head also includes a second outer circumferential mold which fills at least a portion of the first gap, and a third outer circumferential mold which fills at least a portion of the second gap. The third outer circumferential mold fills the second gap at a position which is distanced further from the bottom surface than the second outer circumferential mold in a direction which is perpendicular to the bottom surface, and a hardness of the third outer circumferential mold is higher than a hardness of the second outer circumferential mold.

Liquid ejecting head

A liquid ejecting apparatus includes a head that ejects an ink from a nozzle opening; a moving unit that moves the head; and a heating unit that sets a temperature of a recording sheet onto which the ink is ejected from the head. Before the head ejects the ink onto the recording sheet, the moving unit is moved, and the head is moved to a position opposing a platen and an upper heater, which is a position to where heat radiated from the heating unit is transferred.

A liquid container capable of containing a liquid has a flow passage that is formed in the liquid container and through which the liquid flows, and a filterprovided in the middle of the flow passage. The filterinclines in a direction with respect to the horizontal direction.

Liquid container

A liquid ejecting head has a flow channel substrate, an actuator formed on the flow channel substrate and having at least one mount, and a flexible wiring substrate electrically connected to the mount to supply a drive signal to the actuator. The mount of the actuator and the wiring substrate are bonded together using an epoxy adhesive agent containing p-aminophenol epoxy resin, bisphenol A epoxy resin, and bisphenol F epoxy resin.
