    摘要： In an ink jet printer having pressure generate means for pressurizing ink inside the printer nozzles, either a first electric pulse of an amplitude enabling ink drop ejecting, or a second electric pulse of an amplitude lower than the amplitude of the first electric pulse for mobilizing ink inside a nozzle, is applied to each pressure generator synchronized to a reference signal of a single frequency. An ink drop is not ejected when a low amplitude second pulse is applied to a pressure generating means. Applying said second electric pulse instead stimulates ink around the nozzle so that high viscosity ink at the nozzle tip mixes with low viscosity ink deeper inside the nozzle, thereby lowering the overall viscosity of ink in the nozzle so that ink drop ejecting is easier.

    摘要翻译： 在具有压力产生装置的喷墨打印机中，所述压力产生装置用于对打印机喷嘴内的油墨进行加压，使得能够喷墨的幅度的第一电脉冲或低于用于调动墨水的第一电脉冲幅度的振幅的第二电脉冲 在喷嘴内部，被施加到与单个频率的参考信号同步的每个压力发生器。 当向压力产生装置施加低幅度的第二脉冲时，不会喷射墨滴。 施加所述第二电脉冲而不是刺激喷嘴周围的墨水，使得喷嘴头处的高粘度墨水与喷嘴内部的低粘度墨水混合，从而降低喷嘴中墨水的总体粘度，使得墨滴喷射更容易。

    摘要： An ink jet printer and control method therefor efficiently eliminates temporary ink eject defects during print interruptions. A time interval, i.e., the time lapse between a previous ink ejecting operation and a present ink ejecting operation, is evaluated before printing. If the time interval is less than a first time reference value (t1), an ink purging operation is not performed or is performed only a first minimum number of times. If the time interval is between first and second time reference values (t1.ltoreq.TI
