feature, your fax machine isn’t only a fax machine — it
also can be an image scanner and printer for your computer.
Note: If there is no fax software (see “Requirements for your computer”, below)
installed on your computer, this interface serves no function. So, you must
have installed such software on your computer before you connect the
RS
