Ink jet system

An ink jet system comprising:

• a head unit that includes a nozzle discharging ink, a pressure chamber communicating with the nozzle, and a drive element applying pressure fluctuation to the ink in the pressure chamber by supplying a drive pulse;
• an acquisition portion that acquires output information including one or both of first output information regarding the head unit and second output information regarding the ink used for the head unit;
• a first coupling portion that is communicably network-coupled to a server;
• a first output portion that outputs the output information to the server via the first coupling portion;
• a first input portion to which input information is input from the server via the first coupling portion;
• and
• a determination portion that determines a drive timing of the drive element based on the input information, wherein
• the output information includes information regarding a discharge characteristic of the head unit as the first output information,
• when the discharge characteristic indicated by the first output information is a first discharge characteristic, the drive timing is a first drive timing, and
• when the discharge characteristic indicated by the first output information is a second discharge characteristic higher than the first discharge characteristic, the drive timing is a second drive timing later than the first drive timing.

• the output information includes information regarding a viscosity of the ink as the second output information,
• when the viscosity indicated by the second output information is a first viscosity, the drive timing is a third drive timing, and
• when the viscosity indicated by the second output information is a second viscosity higher than the first viscosity, the drive timing is a fourth drive timing earlier than the third drive timing.
