Control Method, Liquid Ejecting Apparatus, And Ink Jet System

An ink jet system comprising:

• a liquid ejecting apparatus that includes a liquid ejecting head having a plurality of piezoelectric elements, a plurality of pressure chambers which apply pressure to an internal liquid by respectively driving the plurality of piezoelectric elements, and a plurality of nozzles which respectively communicate with the plurality of pressure chambers and from which the liquid is ejected, and that is configured to eject the liquid onto a medium;
• and
• a server provided outside the liquid ejecting apparatus, wherein
• the liquid ejecting apparatus
• acquires residual vibration information on residual vibrations in the pressure chambers after applying a voltage to one or more of the plurality of piezoelectric elements, and
• transmits the residual vibration information from the liquid ejecting apparatus to the server, and
• the server determines whether or not a first abnormality, which is an abnormality caused by the medium colliding with the liquid ejecting head, is generated based on the residual vibration information.
