摘要： A printing apparatus and ink discharge failure detection method capable of precisely detecting temperature information corresponding to each nozzle are provided. Temperatures of respective electrothermal transducers (heaters) are measured on the basis of outputs from a plurality of sensors corresponding to the respective heaters. The temperatures of the heaters at a predetermined timing during a printing operation are predicted on the basis of the temperature change profiles of the respective heaters that are generated by energizing the heaters. A plurality of thresholds corresponding to nozzle states are generated on the basis of the predicted temperatures and the driving conditions of an inkjet printhead, and it is controlled to execute temperature measurement at the predetermined timing. A temperature measured under the control is compared with the respective generated thresholds, and the nozzle state is identified on the basis of the comparison results.

摘要： A liquid ejection head (3) comprises an ejection opening (13) for ejecting a liquid, a passage (24) including a pressure chamber in which an energy generation element for generating energy used to eject the liquid is disposed, an ejection opening portion (13b) that allows communication between the ejection opening and the passage, a supply passage (18) for allowing the liquid to flow into the passage from an outside, and an outflow passage (19) for allowing the liquid to flow out to the outside from the passage. An expression of H -034 × P -0.66 × W > 1.7 is satisfied when a height of the passage at an upstream side of a communication portion between the passage and the ejection opening portion in a flow direction of the liquid inside the passage is set to H [µm], a length of the ejection opening portion in a direction in which the liquid is ejected from the ejection opening is set to P [µm], and a length of the ejection opening portion in the flow direction of the liquid inside the passage is set to W [µm]. The liquid inside the pressure chamber is circulated between an inside and an outside of the pressure chamber.
