Block unwanted fax numbers

If you subscribe to a caller ID service through your phone provider, you can block specific fax numbers so the printer does not receive faxes received from those numbers. When an incoming fax call is received, the printer compares the number to the list of junk fax numbers to determine if the call should be blocked. If the number matches a number in the blocked fax numbers list, the fax is not received. (The maximum number of fax numbers you can block varies by model.)

NOTE: This feature is not supported in all countries/regions. If it is not supported in your country/

region, Junk Fax Blocking does not appear in the Preferences menu.

NOTE: If no phone numbers are added in the Caller ID list, it is assumed that you are not subscribed to a Caller ID service.

You can block specific fax numbers by adding them to the junk fax list, unblock these numbers by removing them from the junk fax list, and print a list of blocked junk fax numbers.
