Fax machine does not receive or send official documents. Try reconnecting the cable (RJ11 phone cable) between the Fax machine and the ATA. This cable should use the ATA's LINE1 port and make sure it is connected to the Line (not Telephone) jack/port on the Fax Machine. Sometimes a bad cable can cause this problem so changing to a new RJ11 phone cable might help.
