Abstract: An ejection inspecting device which inspects an ejection state of an ejection head, including nozzles ejecting fluid, includes fluid receiving areas corresponding to the ejection head so as to receive the fluid ejected from the nozzles. A potential difference generating unit generates predetermined potential differences between the ejection head and the fluid receiving areas. Electrical variation detecting units detect electrical variations of the fluid receiving areas. A control unit drives the ejection head to eject the fluid to the fluid receiving areas from the nozzles in a state in which the predetermined potential differences are generated between the ejection head and the fluid receiving areas by the potential difference generating unit. The ejection inspecting device also inspects the nozzles to determine whether the fluid is ejected from the nozzles on the basis of the detection results of the electrical variation detecting units in the fluid receiving areas.

Abstract: In this ink jet printer, on the basis of voltage of a nozzle plate 27 at the time that a print head 24 is driven and in a state in which a predetermined potential difference has been generated between the nozzle plate 27 and the inspection area 52, a nozzle inspection is performed so as to confirm whether or not ink is in practice being ejected from each nozzle 23, so that ink can be sequentially ejected to an inspection area 52 from each nozzle. According to the nozzle inspection voltage change is detected in the nozzle plate 27 by a voltage detection circuit 54 provided on an encoder board 64 on a carriage 22. Since both the nozzle plate 27 and the voltage detection circuit 54 are installed on the carriage 22, and the distance between the two of them is shorter, they are less likely be affected by noise. In addition, there is no need to prepare a new board on which the voltage detection circuit 54 needs to be mounted.
