1. A printing apparatus comprising:
a printing section that performs printing on a medium containing calcium carbonate;
a transport section including a plurality of transport rollers that rotationally drive a transport belt that forms at least a portion of a transport path in which the medium is transported;
a voltage supply section including a power supply device that supplies a charging voltage to a charging roller for charging the transport belt;
a detection section including a detection circuit that detects whether or not charging abnormality occurs in the transport belt;
a determination section that determines whether a cause of the charging abnormality is abnormality of the voltage supply section or abnormality of the transport belt; and
a machine learning section that performs machine learning of a determination condition in the determination section, based on a learning model in which a rotation amount of the transport belt and a detection result of the detection section are associated with each other.
