2. 调制解调:转换后的电信号会进行调制处理,以便通过通信线路进行传输。在接收端,接收到的信号会经过解调,恢复成原始的电子信号。
3. 传输:调制后的信号通过电话线路或网络线路传输到接收方的传真机。 4. 解码与打印:接收方传真机接收到信号后,会进行解码处理,然后驱动打印机将接收到的文字和图像打印出来。 二、使用技巧 1. 确保良好的通信质量:在发送传真前,要确保电话线路或网络连接稳定,避免因通信质量不佳导致传真发送失败或出现模糊不清的情况。 2. 正确放置文档:在扫描文档时,要确保文档放置平整、对齐,且文稿上的内容清晰可见,这样有利于提高传真的质量和可读性。 3. 检查传真设置:在使用传真机前,要检查传真机的设置是否正确,如号码拨号、传真的分辨率等,以确保传真的顺利发送和接收。 4. 了解并遵守使用规定:在使用传真机时,要了解并遵守相关的使用规定和礼仪,如发送传真的时间、接收传真的方式等。 5. 维护保养:定期对传真机进行清洁和维护,确保其正常工作。如发现故障或异常情况,应及时联系维修人员进行维修。 三、翻译成英文 **Analysis of the Working Principles and Usage Skills of Fax Machines** **Working Principles** A fax machine is a device that can transmit paper documents through electronic signals. Its working principles are mainly based on photoelectric conversion and electronic communication technology. The following is a detailed explanation of the working process and principles of fax machines: 1. Scanning and Photoelectric Conversion: The fax machine first converts the text and images on the paper document into electronic signals through a scanner. In the scanning process, the text and images on the document are converted into optical signals, which are then converted into electrical signals through a photoelectric converter. 2. Modulation and Demodulation: The converted electrical signal is modulated for transmission through the communication line. At the receiving end, the received signal is demodulated to restore the original electronic signal. 3. Transmission: The modulated signal is transmitted to the receiving fax machine through a telephone line or network line. 4. Decoding and Printing: After receiving the signal, the receiving fax machine performs decoding processing, and then drives the printer to print out the received text and images. **Usage Skills** 1. Ensure Good Communication Quality: Before sending a fax, ensure that the telephone line or network connection is stable to avoid fax transmission failures or blurry situations due to poor communication quality. 2. Correctly Place Documents: When scanning documents, ensure that they are placed flat, aligned, and with clear content to improve the quality and readability of faxes. 3. Check Fax Settings: Before using a fax machine, check whether the settings are correct, such as dialing numbers and fax resolution, to ensure smooth transmission and reception of faxes. 4. Understand and Follow Usage Rules: When using a fax machine, understand and follow relevant usage rules and etiquette, such as the time to send faxes, the way to receive faxes, etc. 5. Maintenance: Regularly clean and maintain the fax machine to ensure its normal operation. If any faults or abnormalities are found, contact a maintenance personnel for repair in a timely manner.
