Abstract

The typical problem with an ink jet gutter in an ink jet printer is that there are both consistency and reliability problems in the drop collection process associated with an ordinary gutter made of solid material. In addition, there is the problem of fabricating an intricate front end geometry for the gutter. However, use of a column of liquid as a gutter substantially relieves all the aforementioned problems. The liquid gutter, obviously, needs a continuous flow with proper sump to function satisfactorily. In an ink system, the liquid for the liquid gutter should be the ink itself to simplify the ink recirculation. The advantages of the expected reliability and simplicity of fabrication become more important when the system requirement is an array of closely packed small gutters of complicated geometry. When a liquid gutter system is used the ink supply must be replenished more frequently to overcome the increased rate of ink evaporation.
