Have printed diagnostic report, aligned printheads, aligned printlines, everything on the HP solutions. replaced one printhead several months ago.
SOURCE: k550 air in ink feedlines
I have had this happen a couple of times and have cured it easily. It has only happened with the black with me. It seems to be caused by air in the ink feed line. With the printer switched on open the top cover and hold the resume button for 5 seconds. The printheads should move to the left and you may be able to see air in the pipe(s). Remove the printhead of the offending colour(s) then insert a syringe with the plunger fully down into the rubber that the printhead connects to. Draw up the syringe plunger to draw ink/air through until you can see no more air in the pipe. Replace the printhead and close the cover. The printer should now do a calibration with the offending colour hopefully now working.

try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.
Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

Always try replacing the ink cartridges first.
It sounds like the print heads in the 7780 are bad. Don't confuse the ink cartridges with print heads. The cartridges fit inside the print heads. You will need to change the heads. Here is a link to HP's how-to.

Could have the same problem with the Dell.

It's probably like my Epson...the heads are eithr dirty or misaligned...you should have a computer diagnostic program on CD for your printer if you bought it new...if not, then you can get it from HP or possibly their webpage. The program should include an easy-to-follow alignment procedure done by a USB connection from your comp to your printer, or do the normal head cleading procedure at a service center.

Hi There
Summary
Usage of compatible ink and leave the printer idle too long may cause printhead clogging
What should you do if you get this problem. Relax; you may recover the printhead by unclogging it. Follow these steps to unclog the printhead
1. Right click in the printer driver name
2. Select Properties menu
3. Click Maintenance tab
4. Click on cleaning sign for regular cleaning. Perform this up to 3 times.
5. If this does not work, perform Deep Cleaning
And if that not work
Some times it needs a good clean up but this is up to you if you want to do this,
But after you done this prime the printer so it gets the inks back in the heads, it may take a little time for the inks to work.
Ok.
There is fluid cleaner for this but I can never find any in the shops the only ones I seen is when they sell them in Tesco but they come in with the ink refill bottles so I just use worm water by it self on a cloth and dabbing on the heads to clean them, it will not harm the heads but not to much water.
Some heads are on the inks them self but some have them inside the printer so I not know your printer so if the heads are inside you need to get them out you may find that some heads will just clip out put some need to be unscrewed so you got to know how they come out so be careful and not push to hard on them, if the heads are on the ink then it is a easy job to clean them,
It worth a try it worked for me more than ones.
Please all I ask is call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.
