Abstract
According to an embodiment of this invention, the following processing is performed to solve a problem of accurately determining an abnormal state in a carriage by using an acceleration sensor. Output values from a plurality of acceleration sensors mounted in locations which have low degrees of mechanical/physical coupling in a carriage and a printing apparatus main body are transformed into data in a frequency domain. Subsequently, a carriage operation abnormality and a level of the abnormal state are determined based on a plurality of acceleration values in the frequency domain and a comparison of magnitudes of the acceleration values.
