Printer won't copy with black ink. Page comes out blank. All colors are ok.

Printer will not print black ink page.  Copied a page one day and it worked fine.  Next day I wanted to copy another page and the paper came out blank. I have tried everything that I have found online to do.  Changed ink, cleaned heads, unplugged and replugged. Had the HP printer diagnostic tool, and the HP print and scan doctor go over, and they say all is fine.  I don't know what else to do.  I hate to give up on this printer when all else works fine except the black ink.  I just tried printing something from the computer, and it is light in the black printing, the color is fine.  To copy the page just comes out blank.  I just don't understand this.

Can anyone help me?

The troubleshooting steps in the document here may help resolve black not printing on your Photosmart 5520.   

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.

Thank you so much. It still doesn't print black, just blank page. I will try calling before I give up.

Thank you Bob, but it still will not print in black. Just the lovely blank paper.  The video is not easy for a novice to follow, and hard to understand the man. He kept putting camera down, so I didn't know quite what to do.  I did the best I could.  I will try calling support.  That is always a joy, waiting forever.  If they have no other ideas, I guess I will have to get a new one.
