Introduction With the rapid development of technology, modern communication methods are constantly changing. Fax machines, as one of the traditional communication devices, are still widely used in offices and commercial fields. However, the working principle and internal technology of fax machines are not well understood by everyone. This article will delve into the technical principles and internal structure of fax equipment. II. Overview of Fax Equipment Technology Fax equipment is mainly composed of sending and receiving ends, which communicate through the public telephone network. Its core technology lies in the processes of image scanning, data transmission, and thermal printing. III. Technical Analysis of the Sending End 1. Image Scanning: The image scanner of the sending end converts the document into electronic signals through the principle of photoelectric conversion. This process converts the image information on the document into electrical signals. 2. Data Transmission: The scanned image information is encoded into digital signals and transmitted over the public telephone network through a modem. This process requires the use of specific fax protocols, such as ITU-T T.30. 3. Communication Interface: The sending end needs to establish communication with the receiving end through the telephone line, which needs to comply with telecommunications standards and regulations. IV. Technical Analysis of the Receiving End 1. Data Reception: The receiving end receives the digital signals transmitted by the sending end through the telephone line. 2. Data Decoding: The received digital signals need to be decoded to restore the original image information. 3. Thermal Printing: The decoded image information is printed out through thermal printing technology. V. Internal Structure and Working Principle

The internal structure of a fax machine mainly includes a scanner, transmission module, reception module, and printing module. The scanner is responsible for converting the document into electronic signals; the transmission module is responsible for encoding the electronic signals into digital signals and transmitting them; the reception module is responsible for receiving and decoding digital signals; finally, the printing module prints out the decoded image information.

VI. Conclusion Fax equipment has been widely used in the office and commercial fields due to its stable performance and low cost. With the development of technology, future fax equipment may introduce more advanced technologies such as cloud computing and wireless transmission to meet changing market demands. However, regardless of technological advancements, the basic principles and core functions of fax equipment will remain stable, providing reliable communication services for people.
