Forgotten Admin Password on MFP E67550

[mmsmall]

Company Printer cannot be access via administrator login. Password is forgotten. How can add a new password to access printer via IP address.

Please check your model number.  You can find this information by printing off a configuration page from teh control panel of the printer.

I'm not finding any matches for E67550.

Looks like the E67550 is another name for the M681/682.

Here is a link to the User Guide:

See page 162:

　　

NOTE: Make note of the password and store it in a safe place. The administrator password cannot be recovered. If the administrator password is lost or forgotten, contact HP Support at support.hp.com for the assistance required to completely reset the printer.

That means you need to use a Cold or NVRAM reset to clear the admin password.
