Device for the refilling of a print head of an ink jet printer outside of the ink jet printer, with a holder, into which the print head can be inserted, wherein the print head includes an ink supply chamber, which is in fluid communication with the emission opening of a nozzle plate and which is vented through a ventilation opening, with an ink tank, which by means of a conduit and a coupling piece is capable of forming a fluid connection with a fluid tight sealing engagement with the ventilation opening, a receptacle container, which via a conduit and a coupling piece is sealingly engageable with the nozzle plate for establishing a fluid communication with a fluid tight seal, a pump with a reversible conveyancing direction, which is provided between the ink tank and the ventilation opening, control electronics, which works upon the pump in such a manner, that the ink is conveyed from the ink tank to the ink supply chamber so long, until the desired fill condition is achieved and subsequently the supply direction of the pump is reversed, so that the supply pressure is reduced and, where desired, a predetermined under pressurization can be established in the ink supply chamber, as well as a design of the holder in such a manner, that the print head is positionable in the holder with an essentially upwards directed nozzle plate (refill position).
A device for the refilling of a print head of an ink jet printer outside of the ink jet printer according to a refill process, wherein said print head includes a nozzle plate having an emission opening, an ink supply chamber which is in fluid communication with said emission opening of said nozzle plate, and a ventilation opening, the device comprising:
