Abstract
An ink-jet printer comprises a print head for ejecting ink, an ink tank for storing ink to be ejected from the print head, a piping member connected between the ink tank and the print head, a pump mechanism interposed in the piping member to supply ink from the ink tank to the print head, and a control unit for controlling the print head and the pump mechanism to print an image by ejecting ink. In particular, the control unit is constructed to perform a pump drive processing for driving the pump mechanism to discharge all of ink stored in the ink tank in a displacement mode.
