Abstract
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.
