I have a HP 6515 Photosmart All-in-one printer.I recently put in a new HP black ink cartridge and it printed parts of words. I removed cartridges and replaced them, unplugged and reset, cleaned the ink jets with warm water, used the troubleshooting hints and it now prints blank pages. I just updated my PC to Windows 10 but the problem began before I did that. I am totally frustrated as I need it for work. HELP!
