Patent ID: 7025448

Claim:
A method for ink replenishment in an inkjet printing system employing pigmented ink, the ink comprising solid particles of colorant dispersed in a carrier fluid, the system including an inkjet printhead and a replaceable ink container, and a fluid interconnect providing an ink replenishment path between a fluid interconnect inlet port and the printhead, the method comprising: providing the ink container with an interconnect outlet port, and with a body of reservoir material disposed in the container, the ink container further including a screen disposed across the interconnect output port and in contact with the reservoir material, the screen having a pore size small enough to prevent air passage at operational pressures and large enough to allow said dispersed colorant particles to pass therethrough; bringing the interconnect outlet port and the screen into contact with the fluid interconnect inlet port; drawing ink stored in the container through the screen, the fluid interconnect and to the printhead.
