How to reset the administrator password on an EPSON WorkForce Pro WF-M5799dwf?

[OoooO]

Long time lurker here

Can anyone tell me how to remove the administrator password on an Epson WorkForce Pro WF-M5799dwf printer? I inherited nearly 100 locked devices. I had never worked with Epson devices before. No help from Google

AFAIK you can't without replacing the Main Board.
The default settings allows to make changes if you're in front of the copier, but if the "local" menu is also locked, you're fucked.

You can use ADJ tool from Epson or use maintenance menu, but you will have to visit every single device to do that. ADJ tool is available only for authorised Epson service.
