An ink jet printer is characterised in that a connection part () of an umbilical connected to a connection part of a print head of the printer, comprises: A translation movement alone is necessary to connect the umbilical onto the print head.

Hydroelectric coupling for a printhead and a printer equipped with one such coupling

A twin-nozzle print head for a continuous inkjet deflection printer comprises an ink drop generator assembly having two inkjet ejection nozzles, each of the nozzles having an ejection axis. Charge electrodes, deflection electrodes deflecting charged drops and a single ink drop recovery gutter for both nozzles are also provided. The ejection axes of nozzles converge at a point located on an axis of a single inlet orifice of the single recovery gutter in the vicinity of this orifice or upstream of this gutter. A printer equipped with this head prints swathes of large width with good juncture.

Process and device for cleaning the nozzles of inkjet printers, and print head and printer incorporating such a device

A device permitting the emission or discharge of material in the form of a jet by a nozzle, which is able to communicate with a cavity of the device through which the material passes and where it is pressurized in order to permit the formation of the jet under the effect of a controller. A stimulator is located in the vicinity of the nozzle in order to split up the jet into a succession of elements. The device includes a seal for the nozzle when no material jet is being discharged made of a deformable member placed between the stimulator and the nozzle and designed and positioned so as to seal the nozzle when the controller does not allow the emission of a material jet and to free the nozzle when the controller allows the emission of a jet.

Device permitting the emission of a stimulated jet of pressurized

The invention relates to a modulating device for an ink jet printing head comprising a support (1) supporting a gun (3) equipped with a nozzle or discharging the ink jet, means for introducing pressurized ink (21), means for controlling the ink jet associated with the gun (3), ink filtering means, the gun defining a circuit permitting the circulation of the ink introduced into the assembly up to the nozzle. The filtering means (30) tangential filtering means, draining means (22) being provided for the discharge of the unfiltered ink.

Modulating device equipped with a last chance filter for an ink jet

An ink-jet printing machine which has adjacent printing modules. In each printing module, the ink-jet generating device, the ink-drop deflecting device and the collector for collecting the undeflected drops are borne by a single-piece element located on one face of a supporting beam. The opposite face of the supporting beam bears an ink feeding device, and a container to collect the unused ink coming from the collector and the generation device. The deflecting device is mounted in a pivoting manner so that it can be interposed between the generating device and the collector during the printing operation, and can be withdrawn during the maintenance operation.

Multijet printing module and printing machine including several modules

In a printing device using m ink jets, a head for the deflection of said jets is made in modular form by the assembling of: a first plurality of elements, each comprising m electrodes, a second plurality of elements for the separation of the elements of the first plurality, that are interposed between certain elements of the first plurality to separate these elements electrically from one another; the elements of the first plurality and of the second plurality being aligned and stacked to form a compact assembly.
