Check the date on your ink cartridge. I bet it has expired. If you put in a "new"cartridge but it is even an HP one with an older date, it may not work.
I had my printer stop in the middle of a print job. It was printing fine and suddenly would not print. So I refilled the cartridge with an ink kit I had on hand and reinserted it--no go! Then I opened a remanufactured cartridge (office depot) I had bought some time ago and inserted it. No go, despite the fact I could see ink coming from the jets. I finally gave up and bought a new HP ink cartridge, and it worked just fine. But it bugged me why the new one would work and the other two that seemed just fine would not.
Later I learned that HP has a chip that reads the expiration date on the cartridges and that is what keeps those old ones from printing. I found one trick of setting my date on my computer back to a year earlier than the exp date on the cartridge. I saw the date on the remanufactured one I had tried earlier was 2005, so I set my computer date to today date but year 2004. After forcing me to do print alignments several times and take the remanufactured cartridge out and put it back, I got it to print just fine. And that 2005 cartridge that would not work earlier is what I am printing with right now.
Be advised, though, if you try the date setback, that HP printer will buck and try every way to not let you use that old cartridge. You must say no to reflashing if HP tries to pull that on you. And you will take out and put back that same cartridge multiple times and keep printing alignment sheets 3 or 4 times before you are successful. But, if you persist, you can get it to work.

Hi, the problem seems with the logic board inside the printer, are you in a position to open the printer and try some stunts, that is only if you have done it earlier.. let me know??

if you still have the software completely uninstall the software and drivers and reinstall. go to the hp website and see if there is any updated or fixes for your specific printer. let me know how it works out for you.

I only use refill HP inks. When the cartridge prints gray instead of sharp black it means the ink well is clogged. Yes, that can happen on a new cartridge. Sometimes it happens when they put too much ink in the cartridge, or even heat can make it not work. Also streaking black lines is the problem of the ink not coming out properly. Easiest thing to do is go to a refill station like Cartridge World and have them test it or clean it out. You can also make sure the printer, not the cartridge is clean. Ink builds up an pools. Get some Q-Tips and clean up all that spilled ink. Sometimes in the software it says you can clean the print head, do that too.

Any inkjet printer with this problem is caused by a build-up of ink on the undercarriage or the wiper assmbly.Usually on the right side where the cartridges are at rest. You have to get messy and clean that build-up with moistened cloth, qtips etc.
