摘要

The time required for a nozzle check is minimized without reducing the accuracy of the nozzle check. An inkjet line printer has a nozzle check control unit that performs a nozzle check to detect ejection problems in the nozzles of plural nozzle rows of the inkjet line head. The nozzle check control unit applies the nozzle check to a portion of the nozzles in the group of nozzles in a specific range where two mutually overlapping nozzle rows overlap.
