Printing by deflecting an ink jet through a variable field
For printing, the principle of the continuous deflected jet is used: a device discharges a continuous stream of a liquid, which is deflected by an electric field created by a plurality of deflecting electrodes and directed toward a gutter. The printing of drops is performed by fragmenting the continuous jet into a segment formed opposite a shield electrode upstream of the deflecting electrode, so that the segment is not deflected and can be directed toward a substrate.
The deflection electrodes are separated by an insulator and a variable potential is applied to each electrode; the potential for the entire set of electrodes cancels out such that the jet is not charged.

To clean a print head of an ink jet printer, an ink gun is connected to an ink chamber, a solvent chamber, a vacuum source, and an ink collection gutter, which is capable of being connected in a controlled manner to a vacuum source. During cleaning, an interruption of a hydraulic connection between the gun and the ink chamber is ordered. Next, the gun is connected to the vacuum source. Finally, the solvent chamber is hydraulically connected to the vacuum source via a conduit which includes the ink gun.
