Liquid-ejection testing method, liquid-ejection testing device, and computer-readable medium

A liquid-ejection testing device, comprising:

• a conductive detection member that is arranged in a direction that intersects with a direction in which a plurality of liquid ejecting nozzles that are to be tested are arranged, the detection member being arranged in a state of non-contact with respect to the plurality of liquid ejecting nozzles,
• a detecting section for detecting an induced current generated at the detection member by a charged liquid ejected from each of the plurality of liquid ejecting nozzles, and
• a judging section for judging whether or not ejection of the liquid is being properly performed for each of at least two of the liquid ejecting nozzles, among the plurality of liquid ejecting nozzles, whose relative positions with respect to the detection member are different from each other, based on a magnitude of the induced current that has been detected by the detecting section.

A computer-readable medium for causing a liquid-ejection testing device to operate, comprising:

• a code for ejecting a charged liquid from each of a plurality of liquid ejecting nozzles that are to be tested and that are arranged in a predetermined direction,
• a code for acquiring a magnitude of an induced current generated by the liquid that has been ejected from each of the liquid ejecting nozzles at a conductive detection member arranged in a direction that intersects with the predetermined direction, the detection member being arranged in a state of non-contact with respect to the plurality of liquid ejecting nozzles, and
• a code for judging whether or not ejection of the liquid is being properly performed for each of at least two of the liquid ejecting nozzles, among the plurality of liquid ejecting nozzles, whose relative positions with respect to the detection member are different from each other, based on the magnitude of the induced current that has been acquired.
