Patent ID: 11203206

Abstract:
There is provided an image recording apparatus, including: a conveyer; a recording head; a carriage; a signal output circuit; and a controller. When recording is performed by a multi-pass recording mode, when the number of defective-discharge nozzles is less than a predefined value, when a discharge-defective nozzle, in which a dot recording ratio using a first mask data is equal to or more than a threshold value, is included in nozzles, and when a discharge-defective nozzle, in which a dot recording ratio using a second mask data is equal to or more than the threshold value, is not included in the nozzles, the controller sets the second mask data as a used mask data and performs recording without a suction purge. In other cases, the controller sets the first mask data as the used mask data and performs a purge process before recording as needed.
