Question about HP OfficeJet Pro k550 Printer
I've got a like new HP K550 printer that will not print black. The other color cartridge or this print fine. This is the second time this has happened on this printer. I have run all the utilities that come with it with no results. The first time this happened I replaced the cartridge even though it was still full. This time that doesn't seem to help, I have also replaced the cartridge head.
Hi there is a simple solution to your problem take out the print head place just the jets( where the ink comes out) in warm water for a few seconds while it is in the water use a syringe over each breathe hole at the top of the print head (one at a time) and lightly push air into the head. this process clears any ink clog and frees up the print head and allows it to print propely

I had the exact same problem. The PC helpdesk disconnected me atleast several times claiming my warranty was expired; Eventually I 'installed' the printer on my cousin's iBook and got a replacement printhead (under the still valid and registered warranty) and an important firmware fix:
(But only the black/yellow)
After updating the firmware and I noted that it seems to have changed the cleaning behaviour of the printer, taking a minute rather than grinding for half-an-hour. And the response time for printing is generally a few seconds. But the annoying tendancy to 'lose' ink persists.
One last note:
(or one that is preportedly fixed by firmware)

It seems this affliction is reported many times on the internet, new out of the box the black print head is bad.
1st run the cleaning utility on the driver CD.
If it is in warranty call Hp and give them the info.
it is unlikely the print head is clogged or it would print some garbage.
If it is out of warranty. then feel free to take it out and clean and check/reseat the connections to the print head.
The paper handling jams are the next biggest complaint.
