LINE-DOT RECORDER

WIPO Patent Application WO/2005/028206

A1

A line-dot recorder capable of eliminating the lowering (increasing) of throughput (printing time per sheet) produced when an image is formed by multi-pass dot recording in a specified print area by moving a printing medium with a rotary drum, and efficiently forming high-quality images on a plurality of sheets of printing medium. The line-dot recorder (A) comprises a nozzle head (1) as a recording head having a recording element using many ink-jet-system ink-jet ports (nozzles), a rotary drum (2) provided with its outer peripheral surface close to the nozzle head, a means of feeding sheets to the drum (3), a means of attaching/holding four sheets to the drum (4), and a means of discharging sheets (5), wherein dots are recorded in a sub-scanning direction by a multi-pass (4-pass) method with the drum rotated at quadruple speed to form an image in four rotations, thereby eliminating throughput lowering and obtaining a high-quality image.
