My hp office jet 6962 ran out of black ink, I replaced the catridge

My HP office jet 6962 ran out of black ink it was printing fine until it ran out of ink. I replaced the black ink catridge and now it wont print anything that has black in it. I have cleaned the print head, (several times) and aligned the head but it still doesnt print. The ink is still liquid in the new catridge but I am having no luck

The troubleshooting steps in the document here may help resolve black not printing on your Officejet 6962.

If the standard troubleshooting did not resolve black not printing I would suggest removing the black cartridge.  Turn it over and examine the area around the ink port.  There are four orange plastic spots, left over from the protective cap.  Make sure these are flush with the cartridge body, if not carefully trim them flush.  If the plastic nubs protrude they can prevent the cartridge from seating properly.  Before replacing the cartridge in the printer dribble a few (maybe four) drops of hot water into the ink port in the printer and two drops into the ink port on the cartridge then snap the cartridge back in position.  

It may also help to manually clean the printhead as described in the post here.

I have also seen cases where leaving the printer overnight after the cleaning cycles allows black to recover.

If none of the above restores black printing your printer will likely require repair or replacement.
