Abstract:
A recording device includes a recording head including a plurality of nozzle rows of a plurality of nozzles for ejecting a same color ink, a detector configured to detect, from among the plurality of nozzles, a defective nozzle having an ejecting defect, and a control unit configured to determine whether the recording head is in an error state, based on a detection result from the detector. The control unit determines that the recording head is in the error state when, among the plurality of nozzles having a specific positional relationship in which the nozzles are configured to compensate for each other's ejection, at least a predetermined number the nozzles, which is greater than one, is the defective nozzle.
