Abstract
A method of forming a coating layer on an inkjet head may include: removing ink remaining on an ejection surface of an inkjet head, removing a first coating layer on the ejection surface of the inkjet head, and forming a second coating layer on the ejection surface of the inkjet head. The second coating layer may be formed on the ejection surface without including a step over an entire area of the ejection surface. Accordingly, ink may be ejected in a direction normal (e.g., substantially perpendicular) to the ejection surface.
