APPARATUS AND METHOD FOR COMPENSATING FOR BAD NOZZLE OF INK-JET PRINTER

摘要

An apparatus and a method for compensating a bad nozzle of an ink-jet printer are provided to realize a compensation printing regardless of any color by being compensated with an adjacent nozzle in place of a failed nozzle. In an apparatus for compensating a bad nozzle of an ink-jet printer, a failed nozzle position determination unit(600) determines a position of a failed nozzle. A driving pulse generation unit(610) generates a first driving pulse to discharge an excessive amount of ink droplet for a first driving group including the failed nozzle and the adjacent nozzle. The driving pulse generation unit generates a second driving pulse to discharge a normal amount of an ink droplet for the second driving group without including the failed nozzle and the adjacent nozzle.
