传真机的工作原理及使用方法 一、传真机的工作原理 传真机的工作原理主要是基于光电转换和电子扫描技术。通过将需要传输的文档转换成光信号，再利用扫描器进行电子扫描，然后将扫描得到的信息进行数字编码处理，并通过传输线路进行发送和接收。接收端将收到的信号通过解调技术再次转换回文档形式并输出到打印纸上。 二、传真机的使用方法 1. 安装和设置 首先需要将传真机正确安装在办公地点，连接好电话线。按照设备指示或提供的说明手册设置机器。大多数现代设备有触屏显示面板和友好的界面来方便用户操作和调整设置。 2. 发送传真 在发送传真之前，确保文档已经准备好并放置在传真机的扫描区域上。按照设备的提示，输入接收方的电话号码或传真号码。然后按下“开始”或“发送”按钮，设备将开始扫描文档并将其转换为数字信号进行传输。 3. 接收传真 当接收传真的指示灯亮起时，代表可以接收传真的信息。接听电话，将接收方号码按照电话机的操作输入设备。当接收到的传真完成后，将有相应的提示声或显示信息告知用户。此时，可以将传真文件从传真机中取出并使用。 三、中文翻译英文：

Fax Machine Working Principles and Usage Instructions I. Working Principles of Fax Machine The working principle of a fax machine mainly relies on photoelectric conversion and electronic scanning technology. It converts the document to be transmitted into an optical signal, then uses a scanner to perform electronic scanning. The scanned information is then processed with digital encoding and transmitted through a transmission line for sending and receiving. At the receiving end, the received signal is converted back to a document format through demodulation technology and output onto paper. II. Usage Instructions for Fax Machine 1. Installation and Setup First, the fax machine needs to be installed correctly in the office space and connected to the telephone line. Set up the machine according to the device instructions or provided manual. Most modern devices have a touchscreen display panel and a user-friendly interface to facilitate user operation and adjustment of settings. 2. Sending a Fax Before sending a fax, ensure that the document is ready and placed in the scanning area of the fax machine. Follow the device prompts to input the recipient's phone number or fax number. Then press the "Start" or "Send" button, and the device will begin scanning the document and convert it into a digital signal for transmission. 3. Receiving a Fax When the indicator light for receiving a fax is on, it means that a fax can be received. Answer the phone and input the recipient's number according to the telephone operation into the device. When the received fax is complete, an appropriate tone or display message will inform the user. At this point, you can take out the fax document from the fax machine for use.
