A liquid ejecting apparatus includes: a liquid ejecting head including a wiped surface that includes a first region including nozzles and a second region outside the first region; and a wiping mechanism that wipes the wiped surface, in which a first wiping operation in which the wiping mechanism moves relative to the wiped surface in a first direction to thereby wipe the first region and the second region is performed, and a second wiping operation in which, before the first wiping operation, the wiping mechanism moves relative to the wiped surface in a direction different from the first direction to thereby wipe a region including an upstream portion of the second region, the upstream portion being arranged, with respect to the first region, in a second direction opposite to the first direction, is performed.

A nozzle cleaning apparatus includes a body part, a brush part formed on a first surface of the body part and having a size such that the brush part is inserted into a nozzle to remove foreign substances, and a drive unit for lifting the body part so that the brush part is inserted into the nozzle.

A recording apparatus includes a wiper, a recording head having a step portion and an ejection port surface supporting an ejection port, and a moving unit to relatively move the wiper and the recording head so that the wiper moves with respect to the recording head in relative movement in a first direction. In a first wiping, the relative movement causes the wiper to stop at or in vicinity of the step portion, or pass at or in the vicinity of the step portion at a speed lower than a speed at which the wiper wipes an area in which the ejection port is arranged. In a second wiping performed after the first wiping, the relative movement causes the wiper to pass through the step portion of the recording head and wipe the recording head in the first direction toward the area, and thereafter wipe the area.

Disclosed herein is a print head maintenance cartridge, a printing device and a method of cleaning a print head. The print head maintenance assembly comprises a maintenance cartridge that is movable along a first direction and a wiper assembly comprising a wiper element for wiping a print head. The wiper element extends along the first direction. The maintenance cartridge comprises a guide rail extending along the first direction. The guide rail is to engage with the wiper assembly to adjust a position of the wiper element depending on a relative position between the maintenance cartridge and the wiper assembly in the first direction.

A wiping device includes a wiping member and a moving part. The wiping member wipes a liquid off a nozzle surface of a recording head. The moving part moves the wiping member along the nozzle surface in a predetermined moving direction. The wiping member performs a first wiping operation in which the wiping member is moved while not coming into contact with the nozzle surface but coming into contact with the liquid adhering to the nozzle surface, and a second wiping operation in which the wiping member is moved while coming into contact with the nozzle surface after the first wiping operation.

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.

An image forming apparatus includes a recording head and a wiper. The recording head is provided with a nozzle region where a plurality of ink ejection ports are opened downward. The wiper comes into contact with the nozzle region and moves in a predetermined direction to wipe the ink ejection ports. A head mounting part protruding outward is provided along the wiping direction on a side surface of the recording head at a position higher than the nozzle region. The head mounting part has: an outside portion having a water repellency higher than that of the side surface; and an inside portion provided inside the outside portion and having a water repellency smaller than that of the outside portion.

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 liquid discharge apparatus includes: a head having a lower surface including a nozzle surface in which a nozzle is opened; a wiper making contact with the nozzle surface of the head and wiping the nozzle surface; and a driving part driving at least one of the wiper and the head to thereby cause the wiper to move relative to the head toward one side in a wiping direction in a state that the wiper makes contact with the nozzle surface. The wiper includes: a wiper body having a wiping part wiping the nozzle surface, and a projection projecting from the wiper body toward the other side in the wiping direction. After the wiping part of the wiper body is separated from an end part on the one side in the wiping direction of the nozzle surface, the projection makes contact with the lower surface of the head.
