Administrator password for the pre boot menu on my M551 printer

[Quasimodo1144]

I need the password to open the administrator menu in the preboot. I deleted everything. So I can reinstall the *.bdl file.

By default there is no administrator password in the preboot menu,  and if there is a password someone added it and without that password there is nothing beyond replacing the formatter you can do.

Hello,

To clear the password from the Preboot menu, it is necessary to perform NVRAM initialization of the printer.

To do this, proceed as follows:

1. Turn off the printer.
2. Press and hold the Up arrow and Cancel buttons simultaneously.
3. Turn on the printer.
4. When you see the message Permanent storage init, release the Up arrow and Cancel buttons.
   When the NVRAM init is complete, the printer returns to the Ready state.

   Note: If this does not work, please repeat all steps, but this time press and hold the Down arrow and Cancel buttons.

Don't hesitate to contact us in case of need.

Best regards,

Thank you for your answer

Without a password, the message is displayed that the password is too short. And error 99.09.67 is displayed.

Unfortunately, pressing the buttons does nothing. The display remains dark even though the buttons have been pressed for one minute.
