Abstract
A liquid ejection device comprising a plurality of ejection parts for ejecting liquid in cavities, an inspection part for inspecting the ejection parts. The ejection parts are classified into a plurality of ranks according to the characteristics of individual ejection parts. The inspection part performs inspection in accordance with a determination reference corresponding to the ranks. The inspection is performed consecutively on those among the plurality of ejection parts that are classified in the same rank.
Claims8
A liquid ejection device comprising:
- a plurality of ejection parts for ejecting liquid in cavities from nozzles communicated with the cavities, the liquid being ejected by the driving of a drive element;
- a detection part for detecting the state of the liquid in the cavities;
- and
- an inspection part for inspecting the ejection parts on the basis of a detection value from the detection part;
- wherein
- the ejection parts are classified into a plurality of ranks according to the characteristics of individual ejection parts;
- and
- the inspection part performs inspection of the ejection parts based on the detection value in accordance with a determination reference corresponding to the ranks, the inspection being performed consecutively on those among the plurality of ejection parts that are classified in the same rank.
An inspection method for inspecting a plurality of ejection parts for ejecting liquid in cavities from nozzles communicated with the cavities, the liquid being ejected by the driving of a drive element, the inspection method comprising:
- a detection step for detecting the state of the liquid in the cavities;
- and
- an inspection step for inspecting the ejection parts on the basis of a detection value from the detection step;
- wherein
- the ejection parts are classified into a plurality of ranks according to the characteristics of individual ejection parts;
- and
- during the inspection, inspection of the ejection parts based on the detection value is performed in accordance with a determination reference corresponding to the ranks, the inspection being performed consecutively on those among the plurality of ejection parts that are classified in the same rank.
A liquid ejection device for ejecting liquid from a plurality of ejection parts;
- the liquid election device comprising:
- a plurality of drive elements driven by the application of a drive signal;
- and
- a detection part for detecting electrical signals outputted from the drive elements;
- wherein
- in a case where the detection part consecutively detects electrical signals outputted from the drive elements, the detection part consecutively detects electrical signals outputted from the drive elements of those among the plurality of ejection parts that are of the same rank,
- in a case where the detection part consecutively detects electrical signals outputted from the drive elements, the detection part consecutively detects electrical signals outputted from the drive elements of those among the plurality of ejection parts that are of the same rank.
