ORGANISATION FOR THE COLLECTION OF FERGE BY THE PRESSURE OF FERGRAL

摘要

A system for ink jet printing to collect ink unused during the printing process, and recycle the ink solvent to be reintroduced in the system. The ink stream, after breakup into individual droplets, is selectively charged in a charging tunnel and then passes between a deflection electrode and a collection electrode. The charged droplets are electrostatically deflected to the porous wall of the collection electrode, where they are absorbed. A vacuum pump draws the absorbed droplets into a collection container, which vaporizes the ink solvent and mixes it with air. The solvent-laden air passes through a filter, and is forced through the wall of the deflection electrode in order to control the drying of stray ink drops between the two electrodes.
