Liquid discharge system

A liquid ejecting system includes a head unit that includes a nozzle for ejecting a liquid, a pressure chamber communicating with the nozzle, and a drive element for applying pressure fluctuation to a liquid in the pressure chamber by supplying a drive pulse, an acquisition portion that acquires output information regarding a usage condition of the head unit, a first connection portion that is communicably connected to a server through a network, a first output portion that outputs the output information through the first connection portion, a first input portion to which input information regarding a waveform of the drive pulse supplied to the drive element is input through the first connection portion. A decision portion that decides the waveform of the drive pulse supplied to the drive element based on the input information.

A liquid ejecting apparatus includes a first liquid ejecting head configured to eject a liquid to an ejection direction, a sub-carriage that holds the first liquid ejecting head, and a carriage that holds the sub-carriage. The sub-carriage includes: a first member that is thermally conductive and holds the first liquid ejecting head; and a heating section provided in the first member. The first liquid ejecting head includes a first side wall facing the first member. The first member is located between the heating section and the first side wall when viewed in the ejection direction.

Liquid ejecting apparatus and sub-carriage

A maintenance support system includes a terminal to be connected to one or more devices and one or more autonomous mobile bodies configured to acquire an own location, and transmits abnormality information from an abnormal device to the autonomous mobile body. The autonomous mobile body travels to a location of the abnormal device, based on the abnormality information.

Maintenance support system and terminal used in the same

A liquid ejecting unit includes: a liquid ejecting head; and a coupling member coupled to the liquid ejecting head, in which the liquid ejecting head has a first-coupling portion and a second-coupling portion, the liquid ejecting unit further includes: a first-attachment portion provided in a first-position of the coupling member; a second-attachment portion provided in a second-position of the coupling member, the second position being different from the first position; a first-elastic body; and a second-elastic body, and the first-elastic body biases the first-attachment portion or the first-coupling portion in a state in which the first-attachment portion is in contact with the first-coupling portion and the second-elastic body biases the second-attachment portion or the second-coupling portion in a state in which the second-attachment portion is in contact with the second-coupling portion, so that the coupling member is coupled to the liquid ejecting head.

Liquid ejecting unit and liquid ejecting apparatus

A printing apparatus includes a transport unit that transports a medium in a transport direction, a printing unit that prints on a printing surface of the medium, and a removal unit that is provided on an upstream side in the transport direction with respect to the transport unit and is provided so as to come into contact with the printing surface.

Printing apparatus

Meandering of a medium at a time of transporting is reduced. A recording apparatus which transports medium and performs recording on the medium is provided. The apparatus includes a recording unit, a medium clamping unit which is provided on a side further upstream than the recording unit in a transport direction, and clamps the medium therebetween, and a medium support unit which is provided on the side further upstream than the medium clamping unit in the transport direction, and supports the medium. The medium is slackened between the medium clamping unit and the medium support unit.

Recording apparatus

After the control section of a printer (liquid discharge apparatus) discharges ink on the basis of a print job, the control section waits for an input of the next print job while causing the discharge section to perform flushing. If the next print job is input before the elapsed time Te from the end of the ink discharge on the basis of the print job exceeds the waiting time Tw, the control section causes ink to be discharged on the basis of the next print job. On the other hand, if the next print job is not input before the elapsed time Te exceeds the waiting time Tw, the control section causes the cap to be subjected to capping.

Liquid discharge apparatus

A printer includes a printing unit that performs printing on a printing medium; a winding unit that winds the printing medium on which the printing is performed by the printing unit; and a frame unit which is positioned between the printing unit and the winding unit on a feeding path of the printing medium, in which in a case where the printing medium is not wound by the winding unit, a receiving member for receiving the printing medium is detachably mounted to the frame unit, and in a case where the printing medium is wound by the winding unit, the receiving member is detached such that the frame unit comes in contact with the printing medium.

Printer
