Abstract: A method for restarting a CIJ continuous jet printer after a shutdown of the printer resulting from the full absence of current power, the CIJ continuous jet printer including an ink feed circuit and a removable ink cartridge, the cartridge including a cartridge shell defining at least one volume of the cartridge, an aperture formed in the wall of the cartridge shell, this aperture being hermetically sealed, a pigmented fluid ink and a magnetic stirrer disposed within the at least one volume and movable with respect to the cartridge shell, the volume of the cartridge being in fluid communication with the ink feed circuit, the method including, upon restarting the CIJ continuous jet printer after the shutdown, moving, with respect to the shell, the magnetic agitator, thus stirring the ink in the cartridge.

Abstract: The invention relates to an ink cartridge (30) for a CIJ type printer, such a cartridge including at least one volume (14) delimited by a shell, a sealed aperture (16) of the shell, a fluid ink (17) and magnetic means (15) movable with respect to the cartridge shell.

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.

Abstract: To clean a print head of an ink jet printer comprising an ink gun (1), connected, by means of devices capable of being controlled, to an ink chamber (2), a solvent chamber (8), a vacuum source (16), and an ink collection gutter (22) capable of being connected in a controlled manner to a vacuum source (16), the following steps are performed: (1) an interruption of a hydraulic connection between the gun (1) and the ink chamber (2) is ordered, (2) the gun (1) is connected to the vacuum source (16), (3) the solvent chamber (8) is hydraulically connected to the vacuum source (16) via a circuit (12, 14, 20) comprising the ink gun (1).
