ABSTRACT:
A carriage, which moves an inkjet head group composed of a plurality of inkjet head arrays laid approximately perpendicular to a printing paper transport direction, carries a line charge-coupled device (CCD). The line CCD has a reader element array composed of a plurality of reader elements laid in the same direction as the printing paper transport direction. The line CCD has a width along the printing paper transport direction, which is greater than a width of the inkjet head group. When the carriage moves, the line CCD scans the printing paper in the secondary scanning direction. Ink ejection inspection is made based on an image read by the line CCD.
