HP Officejet pro 7740 - old generation cartridge

[Be2come]

I changed my color cartridge today on my HP Officejet pro 7740 - 

Printer gives and error: Old generation cartridge although I know it is the right cartridge. It might be that I bought several cartridge 1 or 2 years ago to have spares. 

Can HP send me a new cartridge for free or tell me how I can bypass the message in order that I can use this cartridge? 

Thank you

Hi,

This seems to be a big problem , as I also have it. I recently bought a set of cartridges for my 7740 and I get the same message - older generation cartridges. Can you please assist.

Hi,

Thanks for your response. Checked for counterfeit - cartridges are legit. Tried to click the private message link, response is "access denied". Cartridges are Sep 20, printer is Officejet Pro 7740. 

Regards.
