I did a "REFILL KIT" on my empty cartridges. But it didn't do any good. It still acted as if they where empty. Then I noticed when I went into the HP 2000c tools and clicked on "Ink Cartridge Information" It gave me expiration dates on each cartridge. I went and bought new cartridges. I then put the new cap on the old cartridge that I had just refilled. This gave me a new expiration date. But now I have brand new cartridges and old expirations....
SO... The bottom line is, if there isn't a fix for the expiration date code. Then the refill kits for the HP 2000C are for the birds .
