SOURCE: HP Officejet Pro K550 - Printhead Error Message on

I have the same problem. I replaced both printhead cartidges. The MC light stopped blinking, but the KY light kept blinking. I thought it was a faulty new KY ink cartridge. So I returned that cartridge and got a new one. Still the same issue. I called hp and they said the print head is bad now and all they focused on was trying to sell me a new printer. UG! I also heard wiping off the printhead with a dry cloth may help. Did you get yours to wokr?

Tip

HP OfficeJet Pro K550


Recently I posted a message for help and have figure out what was wrong myself. Here is the answer. . . the clicking noise was the printhead latch. It was not fully engaged when a jam was cleared. Seems just pull a smidge so the printhead can come across the carriage. That's it., but now I'm thinking it needs a printhead or two. Printing is sparadic.

I keep getting an error saying my printhead is missing on my lexmark printer


Try to clean the contacts of the printhead and the printer. If it doesn't work, unplug the power of the printer for about 30 seconds and plug it back in.

My HP Officejet Pro K550 is not printing the cyan (blue) ink. It has a new cartridge. I've run print quality pages and configuration pages -- no cyan shows up. I cleaned the printheads and no c


Do a test print...
assuming you have done multiple print head cleans... if it fails to print ANY cyan, I'd guess the print head is dead... although to be honest im not an expert with this hp printer. if that is the case, it probably isnt worth repairing.
If it does print some cyan, just missing, you may be able to find info, sorry, I cant help you there, on accessing the service or maintenance mode and doing a higher level clean, if your printer supports that.
As a last option, disassembly and soaking the bottom of the print head in cleaning solution /water... overnight, without getting ANY water on any contacts, then re running print cleans.

good luck

in my exp, again, not with this printer, mind you, if a print head fails to print ANY ink for a given colour, the print head is usually faulty.

Hope this info helps

1.hp desighnjet 500 showing an exclamation marn on magenta printhead 2. error 59.99 on hp colour laserjet 3700


The exclamation mark means that the magenta printhead is already low in ink or have encounter a problem. Try removing and reinstalling the magenta printhead, if that didn't work, you will need to get a replacement for your magenta printhead since it could be low in ink.

My printer will not print. I get a message saying General Printer Error 0x610000f6 Refer to Printer Documentation. I get the message on both my printer and my computer. When i click the error bubble on the...


Hi there, regarding with the problem that you have..the error message that you are encountering with that machine is something about to work on with the printhead..because the printhead is the one causing the problem why is that the error message keeps on popping up, i believed that the printer model that you have is already out of warranty..the printhead is not replaceable if the printer is out of warranty.. well in that case, quite frankly the printer is already faulty.
you can definitely call HP by dialing this number 1-800-474-6836 and let them see what they can do in their end..
Thanks!

1. Make sure the printer is loaded with unused white paper.
2. Open the printer Toolbox and select the Printer Services tab.
3. Click Clean Printheads . A Clean Printheads window opens. Click Level 1 Clean .
4. Examine the page that prints for print defects.
