Abstract
An ink-jet printer includes a rotary drum for carrying a print sheet, a print head arranged above the rotary drum for printing an image by ejecting ink onto the print sheet, a washing board facing the print head to wash an end surface of the print head with ink ejected from the print head, and a control unit for controlling at a non-printing time the washing board to be set at a cleaning position located between the print head and the rotary drum and the print head to eject ink therefrom. Particularly, the washing board has grooves which receives an entire end surface of the print head and a drain section for draining the ink ejected from the print head and flowing in contact with the end surface of the print head within the groove section.
