please someone can help me with this problem? I can't use any cartridges instead the originals; it's a firmware problem. Where I can find a fix? Thanx for helping me.

@proffo, Welcome to the HP Support Community!

You may refill your cartridges or use remanufactured cartridges, but you may run into problems. HP will not guarantee the functionality of those ink cartridges.

QualityLogic, one of the world's foremost quality assurance organizations, tested the performance of HP inkjet print cartridges vs. remanufactured (refilled) brands. The results: original HP inkjet print cartridges far surpassed ink refills in both print quality and reliability.

Nearly one out of every six refilled ink cartridges tested was dead on arrival or failed prematurely 70% of refilled cartridges had some form of reliability problem Count on HP original ink cartridges for consistent, worry-free printing.

You may think you're saving money on remanufactured or refilled ink cartridges, but in the long run, the cost of wasted time, ink, and paper can more than make up the difference.

Keep me posted for any other assistance.

thank you for support me, I'm looking for a different kind of solution, as opening my printer at any kind of cartridges ( a firmware that doesn't block, i.e.). 

Thanks for the time you spent for me.
