An ink cartridge includes an ink chamber that stores ink. A protruding chamber protrudes upward from the ink chamber in a gravitational direction when the ink cartridge is used. A swing body has a float and a detection portion, and a detection chamber in which the detection portion moves and with which an amount of ink stored in the ink chamber is detected in accordance with a position of the detection portion. In the ink cartridge, a pivot center of the swing body that pivotally moves is disposed inside the protruding chamber.

A discharge apparatus includes a discharge unit configured to discharge a liquid to a medium, a suction unit, and a supply unit configured to supply a gas to the suction unit. The suction unit includes an opening facing the medium, and a suction groove including an arc-shaped inner wall surface inside the opening and configured to suck mist around the medium. An outlet portion configured to blow out the gas supplied from the supply unit toward the inner wall surface is provided in the opening.

The invention relates to a printing device (10) for printing a surface (12), in particular the surface (12) of a workpiece (11) made at least partly of wood, a wood material, synthetic material, composite material or the like, comprising an ink supply device (17) which has at least two ink containers (21), each holding a printing ink (19), and an ink feed system (24) by means of which the printing inks (19) can be supplied to at least one print head (18), in order to carry out a printing process with at least one of the printing inks (19), wherein a flushing device (32) is provided, by means of which at least the ink feed system (24) and/or the at least one print head (18) can be flushed with a flushing liquid (33) for a printing ink change, and to a method for changing printing inks (19) in a printing device (10).

Since ink is not heated at a protrusion connecting an ink supplying device and a print head chip or the like, the viscosity of the ink increases, and the fluidity may not be maintained in some cases. An inkjet printer 1 for solving the above problem includes an inkjet head 300 that ejects ink; a protrusion 310 provided to protrude from the inkjet head 300 and configured to circulate the ink to the inkjet head 300; and an ink flow path portion 6 that supplies the ink to the protrusion 310; where the ink flow path portion 6 includes an ink warming block 200 that heats the ink, and a conducting portion 210 that is formed in the ink warming block 200 itself or separately from the ink warming block 200 and through which heat from the ink warming block 200 is conducted is adjacently disposed outside the protrusion 310.

A liquid ejection head including a liquid distribution path with a first liquid circulation flow path that is branched from the liquid distribution path and a second liquid circulation flow path joined to the liquid distribution path. A flow path wall sections the first and second liquid circulation flow paths and an ejection orifice is provided in each of the second liquid circulation flow path. Energy generating elements and liquid circulating elements are provided in each of the first and second liquid circulation flow paths. A structure is provided on an extension line of a center line of the first flow path wall and is placed at a position at which the structure overlaps the liquid distribution path.

There is provided a liquid discharge apparatus including: a head, a fixing device and a mist collector configured to collect a mist of a liquid. The mist collector and the fixing device are arranged side by side in this order in a first direction. The mist collector is provided with an air channel having a suction port and an exhaust port. The air channel has: a first part and a second part connected to an other end of the first part. The exhaust port is opened, in the second part, toward any one of directions which are: a direction including a direction opposite to the first direction as a directional component thereof, a third direction orthogonal to the first direction and a second direction, and a direction opposite to the third direction.

A controller 10 activates a heater 21 when a temperature detected by a temperature sensor 13 for detecting a temperature of ink becomes lower than a first reference temperature Ta lower than the appropriate ink ejection temperature Ta at the time of printing pause in which printing is paused. After the heater 21 is activated, when the temperature detected by the temperature sensor 13 exceeds a predetermined second reference temperature T2 that is higher than the first reference temperature T1 and lower than the appropriate ink ejection temperature Ta, the controller 10 moves the inkjet head to the maintenance region and forcibly discharges ink from the inkjet head in the maintenance region.

A liquid jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction.

A printer includes: a printhead and a platen positioned below the printhead for supporting print media conveyed along a media feed direction through a print zone. The platen has a particle-collection slot upstream of the print zone relative to the media feed direction and a dam wall at a downstream side of the particle-collection slot. The particle-collection slot and the dam wall extend transversely relative to the media feed direction.
