If user authentication and account track have already been employed, each user needs to send his/her authentication information (the user name and password) to this machine when sending PC-Fax. This limits the users who can send PC-Fax via the machine and prevents unauthorized use by third parties.
When this machine receives a send job from a user who is not authorized to use this machine, or when this machine receives a send job that does not have any authentication information, this machine discards these jobs automatically.
Open the [Configure] tab of the fax driver, and ensure that the user authentication or account track has been set correctly.
If the authentication information is correct, the fax is sent.
