A method for contactless cleaning of a nozzle plate of a print head. The method may include: providing a suction element, the suction element causing a fluid to flow along a surface of the nozzle plate and toward the suction element for removing residue from the nozzle plate; sucking-in, by the suction element, the fluid together with the removed residue; and separating the sucked-in fluid from the sucked-in residue. Also, a suction element for cleaning of such a nozzle plate. The suction element may be configured to cause a fluid to flow along a surface of the nozzle plate and toward the suction element for removing residue from the nozzle plate and sucking-in the fluid with the residue. The suction element may include a mouth piece and a wheel, the wheel being arranged such that the mouth piece is spaced away from the surface of the nozzle plate.

An inkjet recording apparatus allows for cleaning. The inkjet recording apparatus includes an image forming section and a controller. The image forming section has a plurality of nozzles and forms an image on a recording medium by ejecting ink from the nozzles. The controller controls the image forming section. The nozzles eject the ink during the cleaning. The controller includes a determining section, and an adjusting section. The determining section determines whether or not the ink has been ejected from the nozzles. The adjusting section adjusts an ejection amount of the ink in a stepwise manner based on a determination result by the determining section.

In a device for regenerating a print head of an inkjet printing device, a fluid is applied onto the nozzle plate of the print head. The one or more nozzles of the print head can be subsequently operated with one or more no-ejection pulses to produce the effect that fluid is drawn from the nozzle plate into the one or more nozzles and mixes with the ink in the one or more nozzles that the viscosity of the ink in the one or more nozzles is reduced.

An example of an apparatus is provided. The apparatus includes a printhead to dispense a first print fluid and a second print fluid. In addition, the apparatus includes a first nozzle disposed on the printhead. The first nozzle is to eject a first plurality of drops of the first print fluid. The apparatus also includes a second nozzle disposed on the printhead. The second nozzle is offset from the first nozzle by an offset distance along a relative direction of media travel. The second nozzle is to eject a second plurality of drops of the second print fluid. Furthermore, the apparatus includes a textile to receive the first plurality of drops and the second plurality of drops. The textile is to be moved relative to the printhead by the offset distance between ejection of the first plurality of drops and the second plurality of drops.

Provided is a liquid discharging apparatus including a liquid discharging unit configured to discharge a liquid, and a dummy discharge receptacle including an absorbing member configured to absorb a liquid dummy-discharged by the liquid discharging unit, wherein the liquid discharging unit discharges a liquid having a resin content of 5% by mass or greater, and wherein the absorbing member of the dummy discharge receptacle is formed of melamine foam.

It is characterized by: a print head configured to eject ink, which has flowed from a first-channel into a pressure-chamber, from a nozzle by driving an ejection energy generating element installed in the pressure-chamber; a circulation-pump configured to circulate the ink in a circulation channel including the first-channel, the pressure-chamber, and a second-channel that flows the ink inside the pressure-chamber to the outside of the pressure-chamber; a wiping unit configured with a cleaning member that can wipe an ejection port surface of an ejection port and a winding member that winds the cleaning member; and a control unit configured to control a cleaning operation in which the wiping unit wipes the ejection port surface, so that, in a case where the cleaning operation is performed after the circulation-pump is stopped, the cleaning operation is changed based on an elapsed time from the time the circulation-pump stopped driving.

Devices include an inkjet printhead having nozzles and a transport item adjacent the nozzles. The transport item includes vacuum openings adapted to maintain print media on the transport item. The transport item moves the print media in a processing direction. The transport item also includes a jetting area lacking the vacuum openings. The jetting area is elongated and is oriented perpendicular to the processing direction. The nozzles are controlled to eject ink to the jetting area when the nozzles are aligned with the jetting area.

The negative pressure in the ink chamber of a nozzle of a print head is reduced in a printing interruption phase, in particular upon transport of the print head from a cleaning position into a printing position, relative to the negative pressure in a printing phase. The leaking of ink during the printing interruption phase may thus be reliably avoided, and the print quality may be increased.

An inkjet recording apparatus includes an ink ejection head that includes an ink ejector with a nozzle to which ink is supplied, a hardware processor that causes the ink ejector to perform an ejecting action of ejecting ink from the nozzle and/or an projecting action of projecting ink from an opening of the nozzle, and a wiping unit that performs a wiping action of wiping a nozzle opening surface of the ink ejection head, the opening of the nozzle being formed on the nozzle opening surface. The hardware processor controls an operation of the ink ejector so as to cause the ink ejector to perform the ejecting action and/or the projecting action at a timing according to a wiping position of the wiping unit during the wiping action of the wiping unit.

A liquid ejecting apparatus includes a liquid ejecting head which ejects a liquid from a plurality of nozzles disposed on a nozzle surface; an absorbing member which makes contact with the nozzle surface and can absorb a liquid which is adhered to the nozzle surface; and a pressing member which causes the ink absorbing member to contact the nozzle surface by pressing the absorbing member from a side which opposes a side which contacts the nozzle surface. In the liquid ejecting apparatus, a pressure applied to a nozzle peripheral region within the nozzle surface due to the absorbing member which is pressed by the pressing member making contact with the nozzle surface is smaller than a pressure applied to a region other than the nozzle peripheral region within the nozzle surface.
