Block junk fax numbers

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