How to fix the problem “damaged cartridges” if you are using HP 934/950/970 printers?


If you are using HP 934/950/970 (refilled and compatible) cartridges and your HP printer displays the following error (See in the picture below) then you may be a victim of HP’s new security protocol.


To override this security, follow the following procedure:

An update of your printer firmware is necessary.

To get started to ensure that your printer is turned on.

Download your printer firmware.

See the windows update window here your printer serial number will be shown.

  •   If you see it select it and click update.
  •   If your serial number is displayed and you are not able to select it, it means your firmware not need to be updated and press the cancel.
  • If the serial number is not displaying and your printer is running through WIFI, connect your printer to your pc with a USB cable and wait for 20 seconds before clicking update.


  • Once the update is done click ok.

If you have connected via the USB cable for your wifi printer delete the USB driver that is installed with your windows.

ü  Then disconnect your device and reboot your PC. is a leading third-party technical support services provider that gives the best support to the people who use technical devices like printers, antivirus software programs, and routers.
