US 2008/0291239 A1 · INKJET RECORDING APPARATUS

Abstract

This invention discloses an inkjet recording apparatus having an inkjet head with an ejection surface. The ejection surface has a first end, and a second end opposite the first end. The ejection surface also has a first and second control portion, and a contact portion located between the first control portion and the second control portion. Additionally, a number of ejection ports are formed through the ejection surface. The inkjet recording apparatus also includes a wiper and a wiper moving mechanism. The wiper moving mechanism moves the wiper between the first end and the second end. When the wiper is located over the contact portion, the wiper contacts the ejection surface, and when the wiper is located over the first or second control portions, the wiper is located away from the ink ejection surface.
