Provided is a method for manufacturing an element substrate for use in a liquid ejection head for ejecting a liquid to a recording medium. The element substrate, includes: a substrate having a nozzle including an ejection port, and a pressure generating chamber communicating with the nozzle, and subjected to a liquid repellent treatment on a part of a surface on a side opposed to the recording medium; and a generating element for generating an energy for ejecting the liquid. The method for manufacturing an element substrate includes: a liquid repellent treatment step of performing the liquid repellent treatment on the substrate; and a liquid repellent region removing step of removing a part of a liquid repellent region subjected to the liquid repellent treatment so that a non-liquid repellent region not subjected to the liquid repellent treatment is exposed at a surface of the substrate opposed to the recording medium.

The maintenance member has the discharge plane, which is adjacent to the cleaning plane in the cleaning direction and recessed downward from the cleaning plane. This discharge plane is provided between the two extended surfaces, which are extended in the cleaning direction respectively from the two contact planes, in the X direction. In such a configuration, a flow of the cleaning liquid falling down from the cleaning plane to the discharge plane in the cleaning direction is formed. Thus, the amount of the cleaning liquid flowing in the X direction from the cleaning plane can be suppressed.

An inkjet printing apparatus includes: a base; a stage disposed on the base and capable of moving a substrate in a first direction; a first column part disposed on the base; a second column part disposed on the base and spaced apart from the first column part in the first direction; a head part configured to eject ink on the substrate at a fixed position and is disposed on the stage; and a head management part disposed between the first column part and the second column part and capable of moving in a second direction intersecting the first direction.

An ultrasonic vibration-assisted printhead, wherein the printhead comprises a print material reservoir structured and operable to retain a print material, a dispensing nozzle fluidly connected to the print material reservoir and structured and operable to dispense print material received from the print material reservoir; and a piezoelectric ultrasonic vibration printing enhancement module (PEM) operably connected to the dispensing nozzle and structured and operable to generate and propagate ultrasonic vibration to the dispensing nozzle to prevent clogging of the print material within dispensing nozzle during dispensing of the print material.

A printer device (10) includes a base portion (23); an ink discharge unit (30) which is provided on the base portion (23) and to which ink is discharged; and a lid that covers (40) the ink discharge unit (30). The ink discharge unit (30) includes an ink absorbing member (32) capable of absorbing the discharged ink. The lid (40) includes an opening (41a) formed to allow at least a part of the ink absorbing member (32) to be exposed, and is provided to be swingable with respect to the ink absorbing member (32). Preferably, the base portion (23) is provided with a magnet (27) capable of coming into close contact with the lid (40) to keep the lid (40) in a closed state.

A method of operating an inkjet printer operates solvent vapor generators that direct two flows of solvent vapor towards media on each side of each printhead in the process direction. The solvent vapor attenuates the evaporation of ink solvent from ink drops on the nozzle plates or from the ink in the nozzles of the printheads. Thus, the ink on the nozzle plates and in the nozzles does not dry out and the operational status of the inkjets is preserved.

A maintenance mechanism includes a first maintenance unit provided with a plurality of cleaning mechanisms for cleaning a printing head configured to eject a liquid, a second maintenance unit disposed side by side with the first maintenance unit in a transverse direction of the printing head, a support member configured to support the first maintenance unit and the second maintenance unit so as to allow scanning in a longitudinal direction of the printing head, a first positioning member configured to position the printing head at a first cleaning position, and a second positioning member configured to position the printing head at a second cleaning position that is different from the first cleaning position in the transverse direction of the printing head.

Provided is an ink-repellent member including an underlying portion containing an inorganic oxide, the ink-repellent member having a fluorine compound bonded to a surface of the underlying portion, wherein the fluorine compound has a chain structure, and is bonded to the surface by forming a phosphonic acid ester structure at each of both ends thereof.

A casing for a printing apparatus can include a body having a printing opening, and a cover member having an aperture, wherein the cover member is moveable relative to the body between an open position in which the aperture of the cover member is substantially aligned with the printing opening of the body, and a closed position in which at least a part of the cover member substantially closes the printing opening of the body. Further, a printing assembly can include a printing apparatus and a casing, the casing providing ingress protection for the printing apparatus. Finally, a control system for such a printing assembly, and a method of operation of such a printing assembly are provided.

A recording method for discharging, onto the surface of a substrate, an inkjet ink composition containing an organic solvent by using an inkjet head provided with constituent members bonded by a cured product of an adhesive, the organic solvent containing the following organic solvent (a). Organic solvent (a): at least one substance selected from the group consisting of alkylamide-based solvents (a1), cyclic amide-based solvents (a2), and lactone-based solvents (a3).
