An ejection apparatus includes an ejection head having an ejection port, a droplet detection unit, an acquisition unit, a control unit, and a decision unit. The droplet detection unit detects that a droplet ejected from the ejection port has reached a predetermined position. The acquisition unit acquires information regarding a velocity of movement of the detected droplet. The control unit controls the ejection head to eject the droplet from the ejection port. The decision unit decides a number of consecutive ejections of a plurality of droplets from the ejection head based on the acquired information regarding the velocities of each of the plurality of droplets ejected consecutively and detected by the droplet detection unit. If the acquisition unit acquires the information regarding velocities of detected droplets, the control unit controls the ejection head to consecutively eject the droplets from the ejection head based on the decided number of consecutive ejections.

Provided is an ink including water, and an organic solvent, wherein a dried product of the ink has an endothermic peak temperature Tm of 22° C. or higher but 74° C. or lower as measured by differential scanning calorimetry, the differential scanning calorimetry includes first heating, cooling, and second heating, where the first heating is heating the dried product of the ink from −60° C. to 140° C. at a heating rate of 10° C./min, the cooling, which is performed after the first heating, is cooling a heated product obtained in the first heating from 140° C. to −60° C. at a cooling rate of −10° C./min, and the second heating, which is performed after the cooling, is heating a cooled product obtained in the cooling from −60° C. to 140° C. at a heating rate of 10° C./min, and the endothermic peak temperature Tm is an endothermic peak temperature in the second heating.

In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.

A droplet discharging apparatus (10) includes a supporting section (20) including a supporting surface (21) that supports a medium M, a first head (81) including a first nozzle that discharges first liquid onto the medium supported by the supporting surface (21), a second head (82) including a second nozzle that discharges second liquid that promotes curing of the first liquid by reacting with the first liquid onto the medium M supported by the supporting surface (21), a carriage (83) that reciprocally travels in a width direction while holding the first head (81) and the second head (82), an air sending section (70) that generates airflow in the front direction in an discharging area facing the supporting surface, and a shielding section (85) that shields the airflow in the front direction in the discharging area R1.

In one example, a dehumidifier for an inkjet printer includes a condensing unit and a chiller to circulate coolant through the condensing unit. The condensing unit is made of a thermally conductive material forming elongated exterior condensing surfaces and an interior coolant flow passage extending lengthwise between the condensing surfaces.

[Object] To appropriately warm ink.

[Solving Means] An inkjet printer 1 includes an inkjet head 3 and an ink warming mechanism 12. The ink warming mechanism 12 includes a warming part main body 21; an ink flow path 21a formed inside the warming part main body 21; a heater 22 that is attached to the warming part main body 21 and heats the warming part main body 21; a warming part temperature sensor 23 that is attached to the warming part main body 21 and detects a temperature of the warming part main body 21; and a heater controller 4 that controls the heater 22. The heater controller 24 controls the heater 22 based on the detection result of the warming part temperature sensor 23 so that the temperature of the warming part main body 21 becomes a predetermined reference temperature.

A printer includes a printing unit that ejects an ink from an inkjet head onto a medium, and a mist suction unit that suctions mist of the ink. The printing unit includes a first inkjet head, and a second inkjet head provided downstream of the first inkjet head in a transport direction of the medium. The mist suction unit includes a first mist suction device provided between the first inkjet head and the second inkjet head in the transport direction, a second mist suction device provided downstream of the second inkjet head in the transport direction, a first flow path coupling a blower and the first mist suction device, and a second flow path coupling the blower and the second mist suction device. A suction force of the second mist suction device is stronger than a suction force of the first mist suction device.

A printer and corresponding method of printing an image on a surface of a plurality of food products by providing a system having a printer with an extendable and retractable receiving arm and a rotating food product delivery tray for continuously and automatically providing delivery of unprinted food products which are retracted into the printer, printed on, and returned by the receiving arm to the rotatable delivery tray and the tray further moves to deliver subsequent food products for printing.

A liquid ejection device includes a head having a nozzle, an element causing the nozzle to eject liquid, a reservoir configured to store the liquid to be supplied to the nozzle, and a controller. The controller is configured to change a drive signal to drive the element based on a quantity of the liquid stored in the reservoir.

A printer includes an ejecting head that ejects ink, a glued belt including a support surface, a first fan and a second fan configured to blow air toward the support surface, and a facing portion facing a portion of the first fan and a portion of the second fan. The facing portion includes an opening that opens in the Z direction. The opening is located between the first fan and the second fan in the X direction when viewed in the Z direction. When a spacing in the X direction at a first position in the +Y direction is defined as the first spacing and a spacing in the X direction at a second position upstream of the first position in the +Y direction is defined as the second spacing, the second spacing is larger than the first spacing.
