Abstract: A liquid-ejection testing method comprises following steps (A) to (D): (A) A step of making a conductive detection member be opposed, in a non-contact state, to a plurality of liquid ejecting nozzles that are to be tested, the detection member being opposed in a direction that intersects with a direction in which the plurality of liquid ejecting nozzles are arranged. (B) A step of ejecting a charged liquid from each of the plurality of liquid ejecting nozzles. (C) A step of detecting, with a detecting section, an induced current generated at the detection member by the liquid ejected from the liquid ejecting nozzles. (D) A step of 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 detected by the detecting section.

Liquid-ejecting-apparatus maintenance method and liquid ejecting apparatus
Jun Shimazaki
- 07 Feb 2008
TL;DR: In this article, a maintenance method that discharges liquid collected in a liquid receiver 15 of a liquid ejecting apparatus includes a first step of causing a nozzle opening face 43 a of liquid head 3 to be disposed facing the liquid receiver in a non-contact state and applying an electric field between both, a second step of ejecting liquid D from a nozzle 47 to the liquid receivers 15, and a third step of detecting a voltage change based on electrostatic induction at the time of the liquid D to ejecting the liquid from the nozzle.
