**传真设备技术：详解其工作原理** 一、引言 在通信技术日新月异的今天，传真设备虽然不再是主要的通信工具，但其依然在许多场合发挥着重要作用。了解传真设备的工作原理，有助于我们更好地使用和维护这一设备。 二、传真设备工作原理详解 1. 发送端

传真的发送过程主要通过扫描仪和计算机进行操作。首先，发送端通过扫描仪将文档转化为电子信号。这一过程涉及到的技术是光电转换技术，即通过扫描仪的扫描头将文档上的文字和图像转换成光信号，再由光电转换器将光信号转化为电信号。

接着，这些电信号被传输到计算机中，经过一系列的编码处理后，通过调制解调器将信号调制为高频信号。这个高频信号是用于传输的，因为它可以在空气中传播较远的距离。随后，高频信号被转换为无线电波并由发射机发送出去。 2. 接收端 接收端的传真机接收到发送端发送的无线电波后，首先通过接收机将其接收下来。然后，接收机将无线电波转化为高频信号，再由解调器将高频信号还原为原始的电信号。 这些电信号随后被传输到传真机的解码器中，经过解码后，转化为可以识别的图像和文字信息。最后，这些信息通过热敏纸或喷墨打印技术被打印出来，完成传真的接收过程。 三、技术要点 1. 扫描与光电转换：这是将纸质文档转化为电子信号的关键步骤，其准确性和效率直接影响到传真的质量。 2. 调制解调：将电信号转化为适合传输的高频信号和从高频信号中还原出原始电信号的过程，需要稳定可靠的技术支持。 3. 解码与打印：解码器需要准确地将电信号转化为图像和文字信息，而打印技术则决定了传真的清晰度和色彩表现。 四、英文翻译 **Fax Equipment Technology: Detailed Explanation of Its Working Principles** In today's rapidly changing communication technology, fax equipment, although no longer the main communication tool, still plays an important role in many situations. Understanding the working principles of fax equipment helps us better use and maintain this device. Working Principles of Fax Equipment: 1. Sending End: The fax sending process is mainly operated through a scanner and computer. First, the sending end converts the document into an electronic signal through a scanner. This process involves photoelectric conversion technology, which converts the text and images on the document into optical signals through the scanning head of the scanner, and then converts these optical signals into electrical signals by a photoelectric converter. These electrical signals are transmitted to a computer, where they are processed through a series of encoding operations. Then, they are modulated into high-frequency signals through a modem. This high-frequency signal is used for transmission as it can travel a longer distance in the air. Subsequently, the high-frequency signal is converted into radio waves and sent out by the transmitter. 2. Receiving End: After receiving the radio waves sent by the sending end, the fax machine at the receiving end uses a receiver to capture them. The receiver then converts the radio waves into high-frequency signals, which are then restored to their original electrical signals by a demodulator. These electrical signals are then transmitted to the decoder in the fax machine, where they are decoded into recognizable image and text information. Finally, these information are printed out through thermal paper or inkjet printing technology to complete the fax reception process. Technical Points:

1. Scanning and Photoelectric Conversion: This is the key step to convert paper documents into electronic signals, and its accuracy and efficiency directly affect the quality of the fax.

2. Modulation and Demodulation: The process of converting electrical signals into high-frequency signals suitable for transmission and restoring original electrical signals from high-frequency signals requires stable and reliable technical support. 3. Decoding and Printing: The decoder needs to accurately convert electrical signals into image and text information, while printing technology determines the clarity and color performance of the fax.
