发明名称 Inkjet multifunction device having a nozzle malfunction repair function and a method for maintaining the same
摘要 Disclosed are an inkjet multifunction device having a function of attempting to correct malfunctioning nozzles. The inkjet multifunction device includes a printing unit for printing a test pattern, a scanner for scanning the printed test pattern, and a control unit for determining whether respective nozzles in the printing unit malfunction based on the scanned test pattern. The control unit controls the printing unit in order for the nozzles determined as malfunctioned to perform spitting. The determination on whether the nozzles malfunction and the purging of the nozzles are repeatedly performed by the predetermined number of times, and the test step stops if it is determined that all the nozzles normally operate after the repetition operation. Paper and ink can be saved since the purging is selectively performed only on nozzles deemed to be malfunctioning, and meaningless testing and purging operations are prevented from occurring in the case of where there is an absence of malfunctioning nozzles.
