I guess you tried a new cartridge with the same problem.. so try to run the utility tools from the HP soft, you can download it here :

It has also a "Solve a problem" section who might help you.
Then if the problem remain check the contacts in the printer, sometimes ink goes in, dry and stop the contact. Clean it with a hear tip and water (disconnect power and allow to dry before testing)...
Good luck and don't forget to rate.
Cheers

How are you connecting to the printer (over the network or a direct USB connection)? If you are using a USB connection, try a new cable or plugging into a different USB port. If you use a USB hub, try a direct connection.

If you are using a network connection, check if your firewall is blocking the connection. Also check that the router (or switch) didn't dropped the network connection and didn't re-synch with the printer (or worse changed the IP address of the printer).

I hope this helps.

This is normal for this model of HP printer when the ink has 'expired'.
Normally it will print one line from the print head, then check to see if the ink is okay before pumping more ink into the printhead. If it has expired then it pauses in the middle of printing to give the user an opportunity to replace the ink cartridge with a new one, highlight which cartridge needs replacing by lighting and indicator over the 'bad' cartridge.

There are three solutions for this:

1. Buy a new HP Ink cartridge;
   expensive and innefficient, but it will ensure the highest level of quality and continued warranty for your HP printer. And is the least likely to cause problems.
   
   
2. Buy a third-party "refillable" ink cartridge, or MOD chip;
   Less expensive, but still wastes what remaining ink you have in that ink cartridge. Voids the warranty for your HP printer and can lead to a print head clog.
   
   
3. Set your system clock and print like it's 1999;
   Silly printer driver reads the system time to determine if it has expired; will cause the printer log to be inaccurate, and cause problems with software updates, security certificates and other time-sensitive applications. May requirie shutting down both PC and printer simultaneously to be effective.
   
   
4. Crack/Patch or replace the printer driver to remove expiry;
   3rd party replacement drivers are unable to match the resolution of HP's original drivers because they don't know HP's secret PCL codes. Cracking/Patching HP drivers may be illegal depending on where you live and what security clearance you have. It may also possibly sometimes break features like document control and printer logging.
   
   
5. Buy another printer
   Expensive and wasteful.

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?
