Inkjet recording device, and data transfer system and data transfer method including the inkjet recording device

An inkjet recording device comprising:

• an ink tank that stores ink;
• an ejection mechanism that pressurizes ink sent out from the ink tank to form the ink into particulate ink, and ejects the particulate ink;
• a charging electrode that charges the particulate ink ejected by the ejection mechanism;
• a deflection electrode that deflects a flying direction of the ink charged by the charging electrode;
• and
• a gutter that recovers the ink not deflected by the deflection electrode,
• wherein printing is performed by causing the ink deflected by the deflection electrode to land on a workpiece,
• the inkjet recording device further includes
• an operating state acquisition unit that acquires parameter values indicating an operating state of the inkjet recording device, which includes at least one of a pressurization state in the ejection mechanism, a charge state in the charging electrode, a deflection state in the deflection electrode, and/or a recovery state of the gutter,
• a storage unit that stores a plurality of different parameter sets, wherein each of the plurality of different parameter sets is defined in accordance with respective type of assumed trouble and includes parameter values of predetermined types acquired by the operating state acquisition unit,
• a display unit that displays a reception screen for receiving a command to generate a two-dimensional code decodable by a portable communication terminal from a user, and
• a code generation unit that generates, in response to the receipt of the generation command via the reception screen of the display unit, the two-dimensional code associated with any one of the parameter sets stored in the storage unit by encoding parameter values constituting the one of the parameter sets,
• wherein the display unit is configured to display the two-dimensional code generated by the code generation unit.
