Fax (fax) machines are a source of sending copies of the remote locations via the telephone line that are now sent through the server. The great advantage of the fax that it is a stand-alone is the immediate transfer of data. The fax machine consists of a scanner and a modem. Some fax machines are also equipped with printers and copiers. The image scanner scans the image and the modem converts the data into the encrypted message and sends it over the line, which is then reproduced in the receiving terminal. Fax machines are basically two types, analog fax and digital fax machine. In developing this technology was invented centuries before the analog fax machines were used. Although the machine was invented long ago, but it has gained popularity in recent years, more advances in technology and decrease their costs. Today, almost Analog Digital Faxes Faxes replaced. The digital fax, first started in Japan, and now it has spread throughout the world. And by the time the Internet has in this area, this machine has been entered in fashion. The fax server set up through which the data is sent in digital form, through the subscriber lines and digital subscriber lines. Since the data sent in digital form, so that it is now easy to reduce the time be changed to send a page. The original data is compressed and is in a new form of data, which then divided into small packets and sent over the Internet encrypted server to another computer. The other machine decodes and decompresses the data and returns the original as it is. Therefore, the digital fax machine, if one is the speed of the delivery of an edge. So machines are often based on the time they take to transmit classified data. Generally used two methods of data compression, it is Hoffman’s coding and differential Manchester encoding. In each programming word Hoffman with some compression algorithm, and the spaces are excluded and will be encrypted and then sent the message. While scanning in the differential Manchester coding a single line in a time coded, which is then compared with the following coded scanned line, and this difference is sent from the server. Geared to the receiver side terminal of the demodulator and decoder are encrypted documents on this work, the recipient fax machine and the same document produced in less time and incurring a lower cost. These designs are especially helpful for sending international documents, otherwise it may take a very long time to get the data were used only if previous analogue technology to send. Thus, the current needs of the company is required to develop an advanced technology that the ongoing costs of operation can be reduced. This is achievable if the development integrates with all technology functions in one device. So the better idea is to buy it, a fax machine is equipped with high-quality printer, scanner and copier features
