Abstract
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, a first connection portion that is communicably connected to a server through a network, a decision portion that decides a waveform of the drive pulse supplied to the drive element based on first input information, and a first input portion to which the first input information is input from the server through the first connection portion.
Claims18
A liquid ejecting system comprising:
- 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;
- a first connection portion that is communicably connected to a server through a network;
- a decision portion that decides a waveform of the drive pulse supplied to the drive element based on first input information;
- a first input portion to which the first input information is input from the server through the first connection portion;
- and
- a first output portion that outputs output information regarding a degree of deterioration of the drive element to the server through the first connection portion, wherein
- the server includes
- a second connection portion that is communicably connected to the first connection portion,
- a second input portion to which the output information is input through the second connection portion,
- a storage portion that stores correspondence information regarding a correspondence relationship between the degree of deterioration of the drive element and the waveform of the drive pulse,
- a fourth calculation portion that performs a calculation for generating the first input information based on the output information and the correspondence information, and
- a second output portion that outputs the first input information through the second connection portion.
