Zusammenfassung:The present invention relates to the field of continuous ink jet printing and, more particularly, to improved vacuum means for use in continuous ink jet printers. 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.
