How to remove dynamic security

[Shuko]

Hi, please provide instructions for removing dynamic security from my printer. I already tried to update the firmware via HPSmart, but it doesn't work. If an updated driver is needed, please give me a direct link. 

Note: this is not a new question, but when others have asked this question the solution was not given publicly. Instead, a user by the name of "Elohi_NR" asked to be messaged for the solution. So I also messaged this user, and this was the response:

Hi @ Shuko,   I understand you need assistance and I’d love to help. However, we encourage our customers to create a public post so that the conversation may help other community members find a similar solution.   Hence, I would request you to create a public post with the same query,...

Following the user's instructions, I have submitted this public post.

Updating the firmware did not solve the issue.

I am unable to contact support because my device in not under warranty.
