Dear forum, I have simply forgotten my user name and the corresponding password. Now I can no longer change any system settings. How can I reset both?

Search online for a service manual as the instructions are in there. 

If you find the information provided useful or solves your problems, help other users find the solution easier by marking my post as an accepted solution. Clicking "yes" on "was this reply helpful" also increases the chances that this solution will help others.

Thanks for the tip. I have already found the service manual. But I don't know in which section I can find the solution.

 

Is it in Reset Network parameters or in EEROM Reset Utility or in Front Panel Lock Reset? Front Panel lock reset was my hope. I could go to the mentioned Diagnostics menu, but I could not find the option “Front Panel lock reset” as descriped in the service manual. On my plotter (firmware MRY_07_07_05.1) I only have the entry Diagnostic Tests in the Diagnostic menu. But there is no Front Panel lock reset there.
