I have a Dell 3115cn printer that I purchased used on the internet.  I need to reset the password to make changes to the configuration.  Mainly to allow my computer to print.  Currently I get an error code 016-757 (invalid User, Account Denied).  I can't do anything without that password.  I tried using the default password and it does not work.  So i am back to the question, how can i reset the password?
