Liquid cartridge, liquid ejecting device comprising liquid cartridge and main body, method of manufacturing liquid cartridge, and method of refurbishing liquid cartridge

A liquid cartridge comprising:

• a liquid storing portion configured to store liquid therein;
• a liquid path configured to be in fluid communication with the liquid storing portion;
• a sensor configured to output a particular data corresponding to a particular value when the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value when the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge;
• and
• a memory configured to store at least one of the particular data corresponding to the particular value and the further data corresponding to the further value.

A liquid cartridge comprising:

• a liquid storing portion configured to store liquid therein;
• a liquid path configured to be in fluid communication with the liquid storing portion;
• a sensor configured to output a data corresponding to a plurality of values related to a presence or an absence of an object other than the liquid in a predetermined position in the liquid path;
• a memory configured to store at least one of a particular data corresponding to a particular value of the plurality of values that corresponds to the presence of the object in the predetermined position in the liquid path and a further data corresponding to a further value of the plurality of values that corresponds to the absence of the object in the predetermined position of the liquid path.

A liquid cartridge comprising:

• a liquid storing portion configured to store liquid therein;
• a sensor having a characteristic such that an output of the sensor is configured to change based on a state of the liquid cartridge;
• and
• a memory configured to store a particular value related to the characteristic.

A liquid ejecting device comprising:

• a liquid cartridge;
• and
• a main body, wherein the liquid cartridge is removably attachable to the main body,
• the liquid cartridge comprising:
• a liquid storing portion configured to store liquid therein;
• a liquid path configured to be in fluid communication with the liquid storing portion;
• a sensor configured to output a particular data corresponding to a particular value indicating that the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value indicating that the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge;
• and
• a memory comprising a first data corresponding to a first value and a second data corresponding to a second value, wherein the first value and the second value are defined such that when the particular data and the further data are outputted, one half of a sum of the first value and the second value is between the particular value and the further value,
• the main body comprising:
• a mounting portion to which the liquid cartridge is selectively receivable,
• an insertion member configured to be removably insertable into the liquid cartridge;
• and
• a controller configured to retrieve the first data corresponding to the first value, and second data corresponding to the second value, wherein when the insertion member is inserted into the liquid cartridge, the controller is configured to retrieve the data corresponding to the particular value and to determine whether the particular value is less than or equal to one half of a sum of the first value and second value.

A method of manufacturing a liquid cartridge having a liquid path attached to a liquid storing portion, the method comprising:

• storing a first data corresponding to a first value in a memory;
• storing a second data corresponding to a second value in the memory;
• disposing a sensor near the liquid path, wherein the sensor is configured to output a particular data corresponding to a particular value indicating that the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value indicating that the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge, wherein one half of a sum of the first value and the second value is between the particular value and the further value;
• filling the liquid storing portion with liquid;
• and
• plugging the liquid path by disposing a plug in the liquid path.

A method of refurbishing a liquid cartridge having a liquid path attached to a liquid storing portion, a sensor disposed near the liquid path, and a memory comprising a first data corresponding to a first value and a second data corresponding to a second value, the method comprising:

• preparing the liquid cartridge for refilling;
• storing a new first data corresponding to a new first value in the memory to replace the first data;
• storing a new second data corresponding to a new second value in the memory to replace the second data, wherein the sensor is configured to output a particular data corresponding to a particular value indicating that the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value indicating that the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge, wherein one half of a sum of the new first value and the new second value is between the particular value and the further value;
• refilling the liquid storing portion with liquid;
• and
• plugging the liquid path by disposing a plug in the liquid path.
