Good day,
I am using a HP Officejet 7740, and recently, I cannot use 3rd Party Compatible Ink Cartridges anymore. Apparently the machines has been LOCKED so ONLY Original Cartridges can be used? This is UTTERLY ridiculous, and HP is creating a Monopoly that is unacceptable.
If someone have a workaround or idea how I can get the Legally purchused, Non counterfeit compatible cartridges to work on my machine, It will be greatly appreciated.
Regards

Hi @Jakesie
Welcome to the HP Support Community. I'd be happy to assist you with the cartridge issue.
This is a Dynamic security enabled printer. The Firmware Update may prevent supplies with non-HP chips or circuitry from working.
Note: For printers manufactured prior to December 1, 2016 dynamic security will not be enabled by the firmware. Please note that HP cannot guarantee the quality or reliability of non-HP cartridges.
You may refer to this document - HP Printers - Dynamic Security Enabled Printers
Hope this helps! Keep me posted.

Hi, Thanks, but NO THANKS. So, I have no say by choosing to use generic cartridges, even if I accept the fact that it MIGHT affect the print quality? I DEMAND a workaround. It is my right to be able to choose the Generic, much more affordable solotion. Otherwise, this printer is WASTE. I WILL NOT pay two thirds of the price of a printer just for cartridges. NOT AT ALL! If this was a cheap printer, it made sense. But it is not!
I am waiting for my workaround ASAP!
