Print head and liquid ejecting apparatus

A print head assembled to a liquid ejecting apparatus ejecting a liquid with respect to a medium, the print head comprising:

• an ejecting portion electing the liquid in response to a drive signal;
• an electrically erasable non-volatile memory;
• an ejecting module including the ejecting portion;
• a circuit substrate electrically coupled to the ejecting module;
• and
• a housing to which the circuit substrate and the ejecting module are assembled, wherein
• the non-volatile memory is disposed in the ejecting module, and
• the operation state includes at least one of:
• a state where capping processing of attaching a cap to a nozzle where the liquid is ejected from the ejecting portion is executed, and the history information includes how many times the capping processing is executed after the assembly of the ejecting module to the housing;
• a state where wiping processing of wiping a nozzle surface provided with a nozzle where the liquid is ejected from the ejecting portion is executed, and the history information includes how many times the wiping processing is executed after the assembly of the electing module to the housing;
• and
• a state where cleaning processing is executed in the ejecting portion, and the history information includes how many times the cleaning processing is executed after the assembly of the ejecting module to the housing.

A liquid ejecting apparatus comprising:

• a drive signal output circuit outputting a drive signal;
• and
• a print head assembled to the liquid ejecting apparatus ejecting a liquid with respect to a medium, wherein
• the print head includes an ejecting portion ejecting the liquid in response to the drive signal and an electrically erasable non-volatile memory,
• the non-volatile memory stores history information which changes in accordance with an operation state of the print head and which includes information on whether the print head can be recycled or reused, and
• the operation state includes at least one of:
• a state where capping processing of attaching a cap to a nozzle where the liquid is ejected from the ejecting portion is executed, and the history information includes how many times the capping processing is executed after the assembly of the print head to the liquid ejecting apparatus;
• a state where wiping processing of wiping a nozzle surface provided with a nozzle where the liquid is ejected from the ejecting portion is executed, and the history information includes how many times the wiping processing is executed after the assembly of the print head to the liquid ejecting apparatus;
