Office Jet Pro 7720

[AMUG]

I have a OfficeJet Pro 7720 and HP did a Firmware Upgrade which now makes all previous cartridges obsolete.  "The indicated cartridge is an older generation cartridge that does not work in your printer.  It can still be used with some older printer models"

Can someone tell me a workaround or send a link to download the original software.

I looked to see if HP made a fix for this, but I could not find one,

Thank you,

@AMUG, Welcome to the HP Support Community! I’m here to help.

I see that you are not able to use the ink cartridges after updating the printer firmware.

To assist you better, are you using HP inks?

Insert one ink cartridge at a time and check for the error.
