Abstract
A drive arrangement for generating droplets in an ink jet printer incorporates an ink channel with a plurality of discharge openings, and a plurality of conductor loops having their ends secured on both sides of an ink channel, such loops having V-shaped movable central parts located within the ink channel. A magnet system extending over the entire length of the channel generates a magnetic field in the region of the central parts of the drive elements. Each drive element is forced toward its discharge opening by changing the current through the conductor loops, causing an ejection of a droplet from its associated discharge opening.
