I did Fax setup and ran test. All Pass. When I try to send fax the machine dials the number but then I here it say "A carrier access code is required" Does the fax software supply or is it provided by my carrier? Might it be a problem with the line that is connected to my residence. I have DSL and have the machine connected with the adapter supplied by the provider as per fax instructions. The fax is connected with the phone cable supplied by HP, 2 wire copper connector on each end.
