Maintenance system using foaming cleaning bath
A printhead maintenance system includes: an inkjet printhead; a carriage movable longitudinally along the printhead in a cleaning direction, the carriage having a maintenance member including: a fluid bath having a mouth opposing the nozzle face of the printhead, a primary fluid inlet at an upstream end of the fluid bath relative to the cleaning direction, a suction nozzle at a downstream end of the fluid bath relative to the cleaning direction and a pair of wipers flanking the fluid bath; and a traversing mechanism for traversing the carriage along the printhead. The maintenance member does not contact inkjet nozzles of the printhead; the wipers each comprise a wiper material for contacting respective parts of the printhead flanking a nozzle face; and the wiper material is air-permeable such that, in use, suction of air through the wiper material into the fluid bath generates a foam in the fluid bath.
Inkjet recording apparatus
The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.
Liquid discharge device and liquid discharge apparatus incorporating same
A liquid discharge device includes a head including a discharge port. The head discharges a liquid from the discharge port toward an object. The liquid discharge device further includes a liquid receiving surface to receive the liquid discharged from the discharge port, a liquid collector to collect the liquid received by the liquid receiving surface, and a moving unit to hold the liquid receiving surface and the liquid collector. The moving unit is movable at a facing position where the liquid receiving surface faces the discharge port without changing an inclination of the liquid collector with respect to a horizontal plane.
Liquid Ejecting Apparatus and Cleaning Device
A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle that is disposed on a nozzle surface, a wiping member with a lengthwise shape that is able to contact the nozzle surface, a contact portion which is able to contact the opposite side from a side at which the wiping member contacts the nozzle surface, and a transport mechanism which transports the wiping member, in which the contact portion has a first contact portion which is separated from the wiping member when the wiping member is transported by the transport mechanism and which contacts the wiping member when the wiping member is caused to contact the nozzle surface, and a second contact portion which contacts the wiping member when the wiping member is transported by the transport mechanism.
WIPING METHOD AND IMAGE FORMING APPARATUS
A wiping method for wiping a nozzle surface of a liquid discharge head includes the step of relatively moving the liquid discharge head and a wiper impregnated with a cleaning fluid. The cleaning fluid contains a lactone compound in an amount of 5% by mass or more. The wiper includes a first layer configured to contact the nozzle surface and one or more layers other than the first layer. The first layer has a thickness of t1, the one or more layers other than the first layer have a total thickness of t2, and t1 is smaller than t2. A void ratio of the first layer is smaller than a void ratio of at least one of the one or more layers other than the first layer.
Inkjet printing device and inkjet printing method
An inkjet printing device including: an ink storage unit configured to store an ink; an ejection head having a nozzle configured to eject the ink to a printing material; a heating unit configured to heat the printing material; and a washing unit configured to wash a nozzle-formed surface of the head with a washing liquid, wherein the ink is a clear ink including a resin, the device has a low gloss printing mode that is a printing mode for applying low gloss and a high gloss printing mode that is a printing mode for applying high gloss, and the inkjet printing device satisfies: T.sub.matte>T.sub.gloss where T.sub.matte (degrees Celsius) is a temperature of the heating unit when printing is performed with the low gloss printing mode, and T.sub.gloss (degrees Celsius) is a temperature of the heating unit when printing is performed with the high gloss printing mode.
Inkjet recording apparatus
The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The suction unit causes the conveyance belt to suck the sheet. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A ratio of the recessed portions per unit area in a facing region of the conveyance plate facing the head end portion is smaller than a ratio of the recessed portions per unit area in a region other than the facing region.
CLEANING UNIT, SUBSTRATE PROCESSING APPARATUS INCLUDING THE SAME, AND HEAD CLEANING METHOD
Disclosed is a substrate processing apparatus. The substrate processing apparatus includes a head unit including a head having at least one nozzle for ejecting a treatment liquid to a substrate and a cleaning unit that cleans the head, wherein the cleaning unit includes a first cleaning member that sprays a cleaning liquid to the head; and a second cleaning member that forms a suction space in combination with the head when being in close contact with the head, and removes impurities attached to the head by providing a reduced pressure to the suction space.
Printing apparatus with modular printhead system
A single pass inkjet printer that utilizes a modular printing system with one or more self-contained printing modules, where each printing module is easy to remove and replace from a large printing machine, thus resulting in an overall system that is easy to service and maintain. Each module is a self-contained printer including an ink supply, printhead drive electronics, and printhead assembly in order to provide one color or fluid of inkjet printing capability. Each module includes a precise three-point compliant self-aligning mount system to obtain accurate printhead positioning, and a unique integrated printhead tending system that includes a compact movable vacuum knife for cleaning the printheads, and a printhead capping station for sealing and protecting the printheads from the ambient environment when not in use.
LIQUID COMPOSITION, LIQUID DISCHARGING DEVICE, AND METHOD OF MANUFACTURING LIQUID COMPOSITION
A liquid composition contains a coloring material, an organic solvent, a compound represented by Chemical Formula 1 below, a resin, and water, wherein the contact angle of water against a liquid composition film formed by attaching the liquid composition to a non-permeable printing medium is 60 degrees or less,
##STR00001## where n represents an integer of from 4 to 10.
