Abstract
An ink jet printing apparatus can suppress vibrations to a low level without local concentration of abrasion between a carriage and a guide shaft. The ink jet printing apparatus makes the carriage reciprocate along the guide shaft without ejecting ink, thus achieving a stirring operation in which the ink stored in an ink tank is stirred. At least one of a limited range in one direction, in which the stirring operation is performed, and a portion of the guide shaft that contacts the carriage when viewed from the one direction, is changeable.
