    • An ink jet printer has: a vibration detection section to receive ink jetted from the nozzles and output a detection signal having an amplitude corresponding to a vibration generated when the ink lands; a sampling section to sample an amplitude value of the detection signal by a predetermined sampling clock signal; a storing section to store an amplitude value data of the detection signal sampled by the sampling section; a judging section to judge a jet failure of the nozzles based on the amplitude value data of the detection signal in the storing section; and a control section to control to jet the ink continuously a plurality of times with a jet drive cycle which is set by multiplying a standard drive waveform time of an ink jet signal from the nozzles by an odd number not less than five when detecting a jet failure of the nozzles.
    • 喷墨打印机具有:振动检测部,接收从喷嘴喷射的墨水,并输出具有对应于油墨着陆时产生的振动的振幅的检测信号; 采样部分,用于通过预定采样时钟信号对检测信号的振幅值进行采样; 存储部分,用于存储由采样部分采样的检测信号的振幅值数据; 判断部,根据上述存储部中的上述检测信号的振幅值数据来判断上述喷嘴的喷射失效; 以及控制部,其以喷射驱动循环连续喷射墨水,该喷射驱动循环是通过将来自喷嘴的喷墨信号的标准驱动波形时间乘以不小于5的奇数来检测喷射 喷嘴故障。
