Ink jet system for correcting ejection failures

An ink jet system comprising:

• a recording apparatus that is equipped with a head unit having a plurality of nozzles that ejects ink and executes recording processing for recording on a recording medium;
• a processing apparatus that is coupled to the recording apparatus and executes data processing for causing the recording apparatus to execute the recording processing;
• and
• a server configured to be connected to any one of the recording apparatus and the processing apparatus, wherein
• for each of the nozzles in the head unit, judging is executed as to whether a first ejection failure or a second ejection failure has occurred, the first ejection failure being resolved by executing predetermined recovery processing, the second ejection failure being not resolved by executing the predetermined recovery processing,
• when both of a first nozzle that the first ejection failure has occurred and a second nozzle that the second ejection failure has occurred are exist in the head unit, a first correction processing is executed to the first nozzle that the first ejection failure has occurred and a second correction processing is executed to the second nozzle that the second ejection failure has occurred,
• the first correction processing determined a third nozzle of the head unit that is different from the first nozzle in which the first ejection failure occurred,
• the second correction processing determines a fourth nozzle of the head unit that is different from the second nozzle in which the second ejection failure occurred,
• either the recording apparatus or the processing apparatus executes the first correction processing and does not execute the second correction processing,
• the server executes the second correction processing and does not execute the first correction processing, and
• a frequency at which the first correction processing is executed is higher than a frequency at which the second correction processing is executed.
