Abstract
An inkjet printing apparatus has an inspection unit that inspects an ejection condition of multiple ejecting ports arrayed in a first direction, a motor that moves the inspection unit in the first direction, a conversion unit that reduces rotation speed obtained from the motor and converts driving force of the motor into movement of the inspection unit and a control unit that controls inspection of the ejection condition, performed by the inspection unit. The control unit controls the inspection of the ejection condition based on detection of a rotary encoder detecting rotation of the motor and a linear encoder detecting a position of the inspection unit.
