Abstract
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.
