    • One or several jets (14) of an electrically conducting liquid such as ink, are emitted at a given speed Vj and are stimulated so as to form drops (22, 24) at a frequency F, at two break off points (C, L) separated by a distance &Dgr;D less than the wavelength &lgr; of the jet, defined by the relation &lgr;=Vj/F. Two contiguous areas are created (20) in the vicinity of these two break off points (C, L), and the potential of these two areas is brought up to constant electrical potentials with opposite signs (V1, V2). Different quantities of electric charge are thus applied on the drops (22, 24), which are relatively constant even if the break off points should vary. A deflection device (30) then deviates the drops to be recycled (24) and the drops to be printed (22) depending on their charge, which depends on their break off point.
    • 导电液体如墨水的一个或多个喷嘴(14)以给定速度Vj发射,并且在两个断点(C,L)处被刺激以便以频率F形成液滴(22,24) ),其间隔距离DELTAD小于由关系lambd = Vj / F定义的射流的波长lambd。 在这两个断点(C,L)附近产生两个连续的区域(20),并且这两个区域的电位达到具有相反符号(V1,V2)的恒定电位。 因此,不同数量的电荷被施加在液滴(22,24)上,即使断裂点应当变化也是相对恒定的。 然后,偏转装置(30)根据它们的断裂点而偏离待循环的液滴(24)和要打印的液滴(22),这取决于它们的断裂点。
