摘要： A method of compensating a missing nozzle of a printer and a printer using the same. The method includes determining adjacent nozzles corresponding to the missing nozzle, and compensating the missing nozzle by generating dots having an increased size through the adjacent nozzles and generating dots having a normal size through other nozzles when the missing nozzle is generated in the nozzles performing a printing operation. Therefore, it is possible to compensate operations of all color nozzles as well as the black nozzle. As a result, the method of compensating the missing nozzle of the printer compensates operations of the missing nozzle when an image having a composite color is printed as well as when the black image is printed. In addition, it is possible to maintain appropriate image quality by compensating the operation of the missing nozzle through other adjacent nozzles even when a portion of the adjacent nozzles is out of order, since the number of the adjacent nozzles is larger.

摘要： Disclosed is a method for optimizing a driving input signal in an ink jet head using shape memory alloy. The method comprising the steps of: (a) determining a voltage inputted when a replacement generating time in a shape memory alloy layer disposed in the ink jet head is minimal, as a reference input voltage; (b) measuring a first time from a reference input voltage supply starting point to a displacement starting point of the shape memory alloy layer; (c) measuring a second time from after the first time measured in step (b) to a point when a displacement of the shape memory alloy layer is maximal; (d) determining a sum of the first and second times which are measured in steps (b) and (c), respectively, as a reference input voltage applying time; (e) calculating energy applied to the ink jet head, on the basis of the reference input voltage and the reference input voltage applying time which are determined in steps (a) and (d), respectively; and (f) determining a waveform of a driving voltage by measuring a firing velocity and a size of ink droplets while variously changing a voltage and a voltage applying time, such that energy less than the energy which is calculated in step (e) is obtained.
