The housing accommodates the medium support unit and the printing unit. The medium support unit includes a position adjustment unit configured to adjust a position of the support surface in an intersecting direction intersecting the support surface. The position adjustment unit can move the support surface from outside the movement range to within the movement range when the printing is not being performed by the printing unit and the head is disposed at a retracted position.

An apparatus configured as a three-dimensional (3D) printer is disclosed. The apparatus includes a print head assembly, which includes a print head and a nozzle plate, the nozzle plate configured to dispense droplets of liquid provided from the print head. The apparatus includes a build bed configured to receive at least some of the droplets from the nozzle plate, and a service station. The service station includes a spittoon assembly configured to receive at least some of the droplets from the nozzle plate, a vacuum knife assembly configured to remove at least one of: debris, or at least some of the droplets from a surface of the nozzle plate, and a non-contact wash assembly comprising a plurality of weirs configured to upwell a washing fluid and immersively receive the nozzle plate in the washing fluid.

In a liquid discharge head including a discharge-port forming member having a discharge-port row in which a plurality of discharge ports for discharging a liquid which is aligned in a predetermined aligning direction, a plurality of individual liquid chambers which cause each of the plurality of discharge ports to communicate with a common liquid chamber, and an element board having a plurality of elements which generates energy for discharging the liquid and disposed in the individual liquid chamber, a first supply port connecting to the common liquid chamber and a first collecting port connecting to the common liquid chamber, a second supply port disposed further an outer side than an end portion of the discharge-port row in the aligning direction and a second collecting port disposed closer to the outer side than the end portion of the discharge-port row in the aligning direction are provided.

Intended cleaning of a nozzle is enabled without inducing a failure of the nozzle. A drawing machine includes: a print head that ejects ink supplied from an ink tank toward an object to be drawn that is being conveyed; a nozzle group including a plurality of nozzles arranged side by side on one end face of the print head; a purge control section that executes a purge process of causing ink remaining in a flow path from the ink tank to the nozzle group to leak to an outside through the nozzle group; and a cleaning unit that includes a wiping member that wipes off an adhering matter adhered to the nozzle group by the purge process and positions the wiping member with respect to the nozzle group in a state of abutting on the one end face of the print head.

A liquid ejection head including a detachable protection member, includes: a rail portion extending along a first direction; a rail opening formed in the rail portion; and a fixing opening fixing the protection member, in which the protection member includes a protection portion covering an ejection surface of the liquid ejection head, an engagement portion that has a shorter length in the first direction than that of the rail opening, and a fixing portion that is engaged with the fixing opening and that fixes the liquid ejection head and the protection member, the rail portion includes a contact portion at one end in the first direction with which the engagement portion is put in contact, and the other end on an opposite side of the one end in the first direction is connected with the rail opening while the liquid ejection head and the protection member are fixed.

Disclosed is a function film that is a water-repellent film, the function film including at least a water-repellent layer and an unevenness layer. The water-repellent layer has a surface on which a first water-repellent material and a second water-repellent material are exposed, and the unevenness layer contains an inorganic substance as a main component and has a fine unevenness structure.

A liquid ejecting device includes an ejecting unit that includes a nozzle surface at which at least one nozzle is open and that ejects a liquid onto a medium from the at least one nozzle, a carriage that is mounted with the ejecting unit and that reciprocates in a scanning direction, a drying unit that is mounted at the carriage and that dries the liquid ejected onto the medium by the ejecting unit, and a receiving unit that receives the liquid discharged from the at least one nozzle as a result of a maintenance operation for the ejecting unit. The receiving unit includes an absorbing member that absorbs the liquid. The drying unit dries the absorbing member when the ejecting unit is positioned, during printing, at a stop position at which the ejecting unit stops.

The image processing apparatus comprising: a nozzle capable of discharging ink toward a sheet; one or more memory devices that store a set of instructions; and one or more processors that execute the set of instructions to: control a timing of discharging the ink from the nozzle, wherein the one or more processors execute instructions in the one or more memory devices to: execute a first determination of whether or not there is printing using ink for which a predetermined period has elapsed since a past time of use; execute the printing if it is determined that there is printing using ink for which the predetermined period has elapsed; and execute cleaning processing for discharging this ink to the nozzle without executing the printing if it is determined that there is no printing using ink for which the predetermined period has elapsed.
