Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Unfortunately I can't do anything to fix your defective cartridge, that is a HP issue and you can call HP or better yet take it back to target and have them replace it for you.
For the spilled ink, blot that up as best you can with paper towels, then set more towels down on it and pour rubbing alcohol on it, which will act as a solvent to dissolve the ink so that you can keep blotting it up, then just keep dabbing at it with alcohol on towels until it comes away clean.
For the printer itself though, are there further issues? Meaning is it going through the motions but outputting a blank page for example, or giving you any error messages?
Do you need more help with this?If so, simply reply back on this page.
Please note: You have already paid your fee to the site; I'd like to help you and provide value for that fee, but I do need to communicate with you here to do so.
