Protected Cartridge error replace cartridges error.

[Vidstrog]

I've bought two brand new HP 678 cartridges and tried everything to install them but keep getting this error. I've tried disabling cartridge protection., semi-full reset....etc. Nothing works.

When i put my old cartridge it works - but that is low on ink now.

I've read that this is a faulty firmware update and the only fix is a full factory reset. Please can you private message me the full reset instructions to fix the issue. My Model number is : HP inkjet 3540.

Thank you.,

Hi @Vidstrog,

Welcome to the HP Support Community. 

I'd like to help!

Please try it on a Windows computer

• Click on the “start” button on your computer, and then click “Devices and Printers”
• Find your HP printer and double-click it to open the “Settings” page.
• Click the text for “Estimated Ink Levels” under the heading of “Shopping Resources”. This will open the HP Toolbox window.
• Click the tab for “Cartridge Protection”
• Click the radio button next to “Disable HP Cartridge Protection”.
• Click the “Save Setting” button to save your new setting. Then, close the window.
• You might need to remove and re-install the cartridge for it to be recognized properly.

If that does not work then,
