I have had this happen twice with my HP Deskjet 3510.   I got on HP phone support and went through all the steps & tips both times and nothing helped.  Finally, they suggested I try ANOTHER new black ink cartridge, and it worked perfectly.  Apparently, the initial ink cartridges were defective.   HP sent me a new cartridge and I mailed the defective one back to them.
