1 General Information
1.1 Introduction
Thank you for choosing the Di181f and showing confidence in our product.
This machine has a modern design and fulfils today’s requirements of a
fax machine. It combines advanced technology with a contemporary
appearance.
The machine is authorised for use in the public telephone network and is
compatible to other fax machines of the communication standard 3.
The Di181f was manufactured to the same high quality standards as is
common for all other precision instruments made by Minolta.
This manual will assist you in becoming familiar with the machine. It
contains all the necessary information for the start-up, its functions and
the replacement of the consumables.
Please, always keep this manual to hand when using the machine.
1.2 How Does a Fax Machine Work?
A fax machine can be connected to a normal telephone system without
taking any special precautions, just like a normal telephone set. The
function of a fax machine is quite similar to that of a telephone.
The way a fax machine works is simple: Documents that are to be
transmitted are at first scanned. The machine does not recognise the
letters but reads the picture, dot by dot, and marks each dot as black or
white. That is why you can not only transmit texts but also pictures and
photos. The information is then digitised and compressed so that the fax
machine can send it quickly over the telephone line to another fax
machine which reverses the process, reading and marking each dot as
black or white on a sheet of paper.
When you are "called" by a fax machine, your telephone rings as normal.
Therefore you cannot know whether your are receiving a fax call or a
telephone call before picking up the receiver. Those sounds are the so
called "hand shaking" and function as an introduction sequence before the
actual transmission, just as interlocutors - often - introduce themselves at
the beginning of a telephone call. In the introductory sequence the
technical features of both machines are matched to make sure the
transmission and the reception are conducted to a high standard.
With your Di181f you do not need to listen to the introductory sequence.
How to program the machine accordingly will be explained later in this
manual. Furthermore you will also find information about the settings that
