A liquid ejecting apparatus includes a liquid ejecting head configured to eject liquid from a nozzle onto a medium to perform printing, a liquid accommodating unit configured to receive, via an opening, the liquid ejected by empty discharging that ejects the liquid from the liquid ejecting head separately from the printing, a cover movable to a closed position where the opening of the liquid accommodating unit is covered and an open position where the opening is opened, and a detection unit configured to detect the cover positioned at the closed position or the open position.

Additive manufacturing apparatuses, components of additive manufacturing apparatuses, and methods of using such manufacturing apparatuses and components are disclosed. An additive manufacturing apparatus may include a recoat head for distributing build material in a build area, a print head for depositing material in the build area, one or more actuators for moving the recoat head and the print head relative to the build area, and a cleaning station for cleaning the print head.

A liquid discharge head includes a nozzle member. The nozzle member includes a nozzle, a deformable laminar member, and an electromechanical transducer. The nozzle discharges liquid. The deformable laminar member has an opening forming the nozzle. The electromechanical transducer is disposed around the opening. The nozzle member is warped with respect to a discharge-side plane of the nozzle member in a surrounding area of the nozzle when no voltage is applied to the electromechanical transducer.

A supporting section is disposed to confront an ejection surface and supports a recording medium. A first tank is mounted on a first-tank mount section. A liquid conveying section conveys liquid to a liquid ejecting head. A receiving section receives liquid ejected from the liquid ejecting head. A waste-liquid conveying section conveys liquid to the waste-liquid tank. A first casing holds the liquid ejecting head, the first-tank mount section, and the liquid conveying section. A second casing holds the supporting section, the receiving section, the waste-liquid tank, and the waste-liquid conveying section. The first casing is connected with the second casing such that the first casing is movable relative to the second casing. The first casing takes a first position at which the ejection surface confronts the supporting section and a second position at which the ejection surface is farther away from the supporting section than at the first position.

A conveyance control device includes a processor and a memory. The processor is configured to control a conveyor. The conveyor is configured to convey a platen from a conveyance start position of the platen to one of a plurality of printers via a pretreatment device. The pretreatment device is configured to perform pretreatment on a recording medium placed on the platen. The conveyor is configured to convey the platen to one of a first lane including a first printer group formed of a plurality of the printers or a second lane including a second printer group formed of a plurality of the printers. The memory stores computer-readable instructions that instruct the processor to perform determination processing of determining whether to convey the platen to the first lane or to convey the platen to the second lane, based on the recording medium placed on the platen.

A liquid jetting apparatus includes: a liquid jetting head having: a plurality of kinds of individual channels, a jetting surface formed with a plurality of kinds of nozzles from which a plurality of kinds of liquids are jetted, respectively, a plurality of kinds of inflow channels, a plurality of kinds of outflow channels; valves provided at least on the plurality of kinds of inflow channels; a wiper configured to be movable relative to the liquid jetting head in a direction along the jetting surface; a first motor configured to move the liquid jetting head and the wiper relative to each other; and a controller. The controller executes a wiping by driving the first motor in a state that the valves are closed.

A first chart is recorded on a recording medium by discharging ink from predetermined nozzles of a recording head at a plurality of discharge timings set in advance with the detection time point of the recording medium by a recording medium detection sensor as a reference time point, and a second chart is recorded alongside the first chart on the recording medium by discharging the ink from other nozzles of the recording head at a plurality of discharge timings set in advance with the detection time point of the recording medium by the opening detection sensor as a reference time point. A flushing timing, which is set with the detection time point of the opening by the opening detection sensor as the reference time point, is adjusted in accordance with an input of an instruction following the recording of the first chart and the second chart on the recording medium.

A member mountable to a mounting portion provided with an ink receiving tube and a plurality of electrical connecting portions, the member includes a first portion including an outwardly facing surface and provided with an inserting portion into which the ink receiving tube is capable of being inserted; a second portion opposite from the first portion; and a third portion connecting the first portion and the second portion with each other and provided with a plurality of pad electrodes electrically connectable with the electrical connecting portions. The member is mountable to the mounting portion by being inserted into the mounting portion in an inserting direction with the first portion at a leading side. The pad electrodes are electrically connectable with the electrical connecting portions by being moved in a direction different from the inserting direction.

Provided are an inkjet printing apparatus and a recovery method capable of suppressing ink thickening in the ejection openings in the suction process for the ejection openings. A vacuum wiper is moved being in contact with the ejection opening surface of the print head to perform a vacuum wiping process for the arrayed ejection openings sequentially. Ink is circulated in flow paths including the flow paths communicating with the ejection openings for which the vacuum wiping process has been finished.

An object is to provide a liquid ejection apparatus and a method of controlling a liquid ejection apparatus capable of preventing bubbles generated by kogation removal from interfering with the kogation removal. To this end, in a long liquid ejection head with a liquid circulated therethough, a pressure chamber is pressurized and a voltage is applied to a heat applying portion and an electrode to perform kogation removing cleaning.
