HP Photosmart 6510 All in One Printer / Print Scan Copy Web Worked perfectly fine until last week when the black ink wouldn’t come out any longer. Tried a new cartridge to no success and gave up trying to fix it because I had a deadline to print a document. Because of this we now have a new printer and this printer. Works great otherwise, perhaps you can mend it and make it work for you, it does likely need some troubleshooting/repairs though to make the black ink print. All colors worked just fine though along with all other functions of the printer/copier working.
