Abstract: A head cleaning method includes contacting a nozzle surface of a head in which nozzle holes are defined with an absorbent on a pressurizer, starting a wiping operation at a first edge portion of the head closest to the pressurizer at a first position, and ending the wiping operation at a second edge portion of the head furthest away from the pressurizer at the first position, positioning the pressurizer at a second position to define a first angle between a first imaginary line parallel to a longitudinal direction of the head and a second imaginary line parallel to a longitudinal direction of the pressurizer, and starting the wiping operation at a third edge portion of the head closest to the pressurizer at the second position, and ending the wiping operation at a fourth edge portion of the head furthest away from the pressurizer at the second position.
