초록 ▼

A modified syringe for recharging an ink supply in a print cartridge is described. In the preferred embodiment, the end of a syringe valve is inserted into the end of a print cartridge valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further insertion causes both valves to become open, thus creating an airtight fluid path between the syringe chamber and the depleted print cartridge reservoir. A negative pressure within the print cartridge ink bag draws the ink from the syringe chamber into the ink bag until the ink bag is substantially full and the pressure in the ink bag is at or near atmospheric pressure. An air intake port is provided on the syringe to fill the void left by the ink in the syringe chamber. Once the print cartridge has been recharged, a plunger in the syringe is manually pulled back a predetermined distance to draw an amount of ink out of the print cartridge to create the desired negative pressure in the print cartridge. The syringe is then removed from the print cartridge, automatically pulling the two valves closed.

대표청구항 ▼

[ What is claimed is:] [1.] A method for recharging a print cartridge reservoir with ink while said print cartridge is installed in an inkjet printer comprising:providing a print cartridge in a scanning carriage in an inkjet printer, said print cartridge having an ink recharge port;connecting an ink outlet port of a syringe to said recharge port on said print cartridge while said print cartridge is provided in said scanning carriage, said step of connecting creating an airtight fluid path between a chamber of said syringe and said reservoir within said print cartridge;allowing ambient air to enter said chamber while ink within said chamber is drawn into said reservoir by a negative pressure in said reservoir relative to a pressure in said chamber;pulling back on a plunger within said chamber, after said reservoir is sufficiently recharged with ink, to withdraw an amount of ink from said reservoir to create a desired negative pressure within said reservoir; andsealing said recharge port of said print cartridge, while said reservoir is at said negative pressure, to prevent air ingestion into said reservoir.
