A supporting section is disposed to confront an ejection surface and supports a recording medium. A first tank is mounted on a first-tank mount section. A liquid conveying section conveys liquid to a liquid ejecting head. A receiving section receives liquid ejected from the liquid ejecting head. A waste-liquid conveying section conveys liquid to the waste-liquid tank. A first casing holds the liquid ejecting head, the first-tank mount section, and the liquid conveying section. A second casing holds the supporting section, the receiving section, the waste-liquid tank, and the waste-liquid conveying section. The first casing is connected with the second casing such that the first casing is movable relative to the second casing. The first casing takes a first position at which the ejection surface confronts the supporting section and a second position at which the ejection surface is farther away from the supporting section than at the first position.

Maintenance system using foaming cleaning bath
11577517 · 2023-02-14 · ·

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.

Image forming apparatus and flushing control method for assigning respective dot patterns for use in flushing with inks of different colors according to number of overlapping dots in image

An image forming apparatus includes a recording head that ejects inks of different colors on a recording medium to form an image based on image data, a storage device that stores a plurality of different dot patterns for flushing, and a control device that functions as: a controller that allows the recording head to make flushing; an image area detector that detects an image area in the image data; an overlapping dot counter that counts a number of overlapping dots for each of the plurality of dot patterns according to which flushing is to be made on the image area, the number of overlapping dots being a number of dots in the dot pattern of the ink ejected on the image area; and a dot pattern assignor that assigns, according to the number of overlapping dots, the respective dot patterns for use in flushing with the inks of different colors.

Liquid discharge apparatus

A liquid discharge apparatus is provided, which comprises a conveyor, a support member which supports a medium existing in a conveying passage, a head, a maintenance mechanism which has a wiper, and a wiper cleaner. The maintenance mechanism is opposed to a nozzle surface of the head and movable to a wiping position at which the wiper abuts against the nozzle surface and a cleaning position at which the wiper abuts against the wiper cleaner. The wiper cleaner is disposed at a position at which a part thereof is overlapped with the support member in a direction orthogonal to the nozzle surface under or below the support member.
