    Does anyone have a good understanding of how these ink carts function?

    I am attempting to refill them, and not having a lot of luck. They have a foil bag inside, and short of puncturing the bag I don't see how to do this.

    The output valve seems to have a secondary check valve in it, I disassembled it, but still unable to force ink inside, even with a fairly sharp needle.

    My second concern is they have a membrane that appears to allow for the air pressure to be pumped inside the cart, but exterior of the ink bag to force it into the printer. What is the common practice to cut that film, as I assume it must be resealed to hold pressure when reassembled.

    Suggestions? Thoughts? Information?
