Well, I've searched this site and to the end of the web. The problem is my HP photosmart C-5180 printer won't recognize some new "compatible" cartridges (HP 02). AFTER I bought them, THEN the seller tells me that "after they researched it, other customers are reporting problems w/ compatible carts & C-5100 / 6100 series printers". Other retailers have now also told me the same. I'm looking for a workaround. My problem is that the printer won't recognize the new cart, NOT that it says it's empty. Error message: "cartridge(s) is missing or damaged." Obviously, HP has rigged this printer & the HP 02 cart so generic carts won't work.:dead: I went through all the steps that the inkseller suggested to "trick" the printer into recognizing the compatible carts. HA! But, just like everything else, there must be a hack for this. Suggestions or links would be appreciated.
