Abstract
An ink jet method and apparatus including circuitry for controlling lateral deflection of an ink column before drops are formed. A deflection mechanism used to deflect the column comprises two electrode portions spaced on opposed sides of the column. By control of the voltages applied to the electrode portions the angle of ink column deflection is made proportional to a control voltage applied to the portions. This proportionality facilitates control over column scanning to insure proper ink drop placement on the ink jet recording medium.
