Patent number: 7971957Abstract: An ink-jet line printer (30) is constituted by multiple ink-jet heads (1-1 to 1-3). Actuators (3-1 to 3-3) are arranged so as to be moved between a home position and a print position, and backup mechanisms (2-1 to 2-3) are arranged at home positions. In this ink-jet line printer, the ink-jet heads can be protected and recovered by backup mechanisms, thus making high-speed continuous printing possible. Even though the backup mechanisms are incorporated, a compact apparatus can still be achieved.Type: GrantFiled: June 5, 2007Date of Patent: July 5, 2011Assignee: Fuji Xerox Co.,Ltd.Inventors: Koichi Sanpei, Mitsuhiro Mori, Akira Iwaishi, Shigeyoshi Nakamura, Katsumi Tateno
