    • An improved continuous ink jet print station includes a drop generator with a jet array (14) and a drop charging assembly (16). The drop charging assembly includes a substrate (18) with a first side (20) facing the jet array, and one or more resistive heater elements (22a-22f) placed on the substrate aligned with the jet array. The resistive heater elements are discontinuously disposed on portions of the substrate. One or more one charging electrodes (24) are disposed on the first side. The continuous ink jet print station includes a power source (26) for powering the resistive heater elements to heat the substrate to a temperature sufficient to prevent condensation of fluid on the first side.
    • 改进的连续喷墨印刷台包括具有喷射阵列(14)和液滴充电组件(16)的液滴发生器。 该液滴充电组件包括具有面对射流阵列的第一侧(20)的衬底(18),以及放置在与衬底对准的衬底上的一个或多个电阻加热器元件(22a-22f)。 电阻加热器元件不连续地设置在衬底的部分上。 一个或多个充电电极(24)设置在第一侧上。 连续喷墨印刷站包括用于为电阻加热器元件供电的电源(26),以将衬底加热到​​足以防止流体在第一侧上凝结的温度。
