Inkjet printing apparatus

An inkjet printing apparatus for performing printing on a printing medium comprising:

• a print head including an ejection port array including a plurality of ejection ports to eject ink;
• a scanning unit, on which the print head is mounted to perform scanning in a first direction;
• an examination unit, including a light source and a light receiving device, for receiving light emitted by the light source, so as to be able to perform examination of an ink ejection state for a target ejection port based on an output change of the light receiving device when an ink droplet ejected from the target ejection port is passed between the light source and the light receiving device;
• and
• an inspection position moving unit on which the examination unit is mounted, for moving in the first direction,
• wherein the inspection position moving unit has positioning accuracy higher than that of the scanning unit.
