摘要： A system and method are provided for improving the reliability for shutting down high resolution ink jet printheads for continuous ink jet printers. The shutdown technique fo the present invention solves the problem of ink and/or flush fluid drying in or around orifice holes on higher resolution printheads. This is accomplished with pulse modulation of air pressure used to blow and dry the printhead filters while balancing air flow and negative pressure across the droplet generator and the orifice array.

摘要： A system and method are provided for protecting the vacuum pump of an ink jet printer system from the harmful effects of condensation in the vacuum lines, and from the harmful effects of moisture and water in the vacuum lines. This is accomplished by suppressing the condensation and drying the vacuum line walls.

摘要： A system and method are provided for cleaning the printhead of a continuous ink jet printing system. A cleaning fluid is introduced and used to flush ink residues and debris from the interior of the drop generator, the exterior of the orifice plate, the charge plate face and the catcher face. This system and method removes dried ink residues and other debris and deposits by providing a cleaning fluid with a low surface tension to dissolve or flush away the unwanted material from the orifices. This is particularly advantageous in that the flushing and rinsing is accomplished without mechanical contact which could abrade or damage the orifices.
摘要翻译：提供了用于清洁连续喷墨打印系统的打印头的系统和方法。引入清洁流体并用于从液滴发生器的内部，孔板的外部，充电板表面和捕获器表面冲洗墨水残余物和碎屑。该系统和方法通过提供具有低表面张力的清洁流体来清除干油墨残留物和其它碎屑和沉积物，以从孔中溶解或冲洗不需要的物质。这是特别有利的，因为冲洗和冲洗是在没有可能磨损或损坏孔的机械接触的情况下完成的。
