办公设备之传真机的原理与操作 一、传真机原理 传真机是一种能够发送和接收文本、图像和其他可视信息的设备。它的工作原理主要基于光电转换和静电吸引技术。具体来说，它的工作流程可以分为以下四个步骤： 1. 扫描与编码：当我们要发送一个文档时，我们会通过传真机的扫描仪将其转换为数字信息。这个过程中，文本和图像被扫描并转化为光信号。然后，这些光信号被转换成电信号，并进一步被编码为二进制代码。 2. 调制与传输：当数字信息编码完成，它会经过一个称为“调制解调”的过程，以便能够在不同的传输线上传输。此过程中，传真机会利用各种形式的通信方式，例如电话线、互联网等，将信息传输到目标传真机。 3. 接收与解码：在接收端，接收到的信号会被解调和解码，然后再次被转化为光信号。 4. 打印与输出：最后，这些光信号再次被转换为电信号并作用于感光鼓上，形成文字和图像的静电潜像。通过静电吸引技术，墨粉被吸附在潜像上，然后通过热定影技术将墨粉固定在纸上，从而形成最终的文档。 二、传真机操作 操作传真机的基本步骤如下： 1. 开机与设置：首先，你需要打开传真机并设置相应的模式和号码。你可能需要按下一些按键或通过显示屏进行设置。

2. 发送文档：将需要发送的文档放入传真机的扫描区域，并按下发送键或开始键。在发送过程中，你需要确保电话线连接正常，并且电话已经拨通目标传真机的号码。 3. 接收文档：当其他传真机发送的信号到达你的传真机时，你只需要按下打印键或接受键，然后按照屏幕上的指示操作即可。 三、翻译成英文 Office Equipment: The Principles and Operation of Fax Machines I. Fax Machine Principles A fax machine is a device that can send and receive text, images, and other visual information. Its work is mainly based on photoelectric conversion and electrostatic attraction technology. Specifically, its workflow can be divided into the following four steps: 1. Scanning and Encoding: When we want to send a document, we will convert it into digital information through the scanner of the fax machine. In this process, text and images are scanned and converted into optical signals. Then these optical signals are converted into electrical signals and further encoded into binary code.

2. Modulation and Transmission: When the digital information is encoded, it will go through a process called "modulation and demodulation" to be able to transmit on different transmission lines. During this process, the fax machine will use various forms of communication, such as telephone lines, the Internet, etc., to transmit information to the destination fax machine.

3. Reception and Decoding: At the receiving end, the received signals are demodulated and decoded, and then converted into optical signals again. 4. Printing and Output: Finally, these optical signals are converted into electrical signals again and act on the photosensitive drum to form an electrostatic latent image of text and images. Through electrostatic attraction technology, the ink powder is adsorbed on the latent image, and then fixed on the paper by thermal fixation technology to form the final document. II. Fax Machine Operation The basic steps for operating a fax machine are as follows: 1. Power On and Settings: First, you need to turn on the fax machine and set the appropriate mode and number. You may need to press some buttons or use a display screen for settings. 2. Sending Documents: Place the document you want to send in the scanning area of the fax machine and press the send or start button. During the sending process, you need to ensure that the telephone line is connected properly and that the phone number of the destination fax machine has been dialed. 3. Receiving Documents: When a signal from another fax machine arrives at your fax machine, you simply need to press the print or accept button and follow the instructions on the screen to operate it.
