Line type ink-jet printer

摘要

There is described an ink-jet printer by which high speed image formation can be carried out, and in which image failure due to a defective nozzle can be improved. The disclosed ink-jet printer includes a first printing head (2) to emit ink particles, being a line-type head in which a plurality of ink-jet nozzles are arranged in a line and a second printing head (2') to emit ink particles having a color same as that of the ink particles emitted by the first printing head. Another example of the disclosed ink-jet printer includes a printing head to emit ink particles, a nozzle checking device (6) for detecting a defect of the ink-jet nozzle mounted in the printing head and a driving unit for moving the printing head in a direction of the line. The nozzle checking device may be a laser nozzle checking device. <IMAGE>
