了解传真设备的核心部件与技术参数 传真设备是现代通信技术的重要组成部分，它通过电子方式将文件、图像和文字从一台设备传输到另一台设备。传真设备的核心部件和技术参数对于其性能和功能起着至关重要的作用。 一、核心部件 1. 扫描器：扫描器是传真设备中最重要的部件之一。它负责将原始文档（如纸张）上的图像或文字转换成电子信号。扫描器通常由光源、透镜和传感器等组成，能够将文档上的信息转化为数字信号。 2. 调制解调器：调制解调器是传真设备中的关键部分，它负责将扫描器转换的数字信号进行编码和解码。调制解调器使用特定的协议将数字信号转换成可以在电话线上传输的信号，并在接收端将接收到的信号解码回原始的数字信号。 3. 发送器与接收器：发送器和接收器是传真设备中用于发送和接收信号的部件。发送器将调制解调器处理过的信号发送出去，而接收器则负责接收来自另一台设备的信号。 4. 控制面板：控制面板是用户与传真设备交互的界面，它包括各种按钮和显示屏，用于设置传真参数、发送和接收传真等操作。 二、技术参数

1. 分辨率：分辨率是衡量传真设备性能的重要参数之一。它表示设备能够捕捉和传输的图像细节的多少，通常以每英寸点数（DPI）或每毫米点数（DPMM）来表示。高分辨率的传真设备能够传输更清晰的图像和文字。

2. 传输速度：传输速度是指传真设备在单位时间内能够传输的数据量，通常以每页传输所需的时间来衡量。传输速度越快，用户等待的时间就越短。 3. 兼容性：兼容性是指传真设备能够与其他设备和系统进行通信的能力。现代传真设备通常支持多种通信协议和标准，以便与不同类型的设备和网络进行连接和通信。 4. 错误率：错误率是衡量传真设备可靠性的重要指标之一。它表示在传输过程中出现错误或故障的频率。低错误率的传真设备能够保证传输的可靠性和稳定性。 Translation: Understanding the Core Components and Technical Parameters of Fax Devices Fax devices are an important part of modern communication technology, transmitting files, images, and text from one device to another through electronic means. The core components and technical parameters of fax devices play a vital role in their performance and functionality. I. Core Components 1. Scanner: The scanner is one of the most important components of a fax device. It is responsible for converting the images or text on the original document (such as paper) into electronic signals. Scanners are usually composed of a light source, lens, and sensor, converting the information on the document into digital signals. 2. Modem: The modem is a key part of a fax device, encoding and decoding the digital signals converted by the scanner. Modems use specific protocols to convert digital signals into signals that can be transmitted over telephone lines, and decode the received signals back to the original digital signals at the receiving end. 3. Transmitters and Receivers: Transmitters and receivers are the components used to send and receive signals in a fax device. The transmitter sends the signal processed by the modem, while the receiver is responsible for receiving signals from another device. 4. Control Panel: The control panel is the interface for users to interact with the fax device, including various buttons and displays for setting fax parameters, sending and receiving faxes, etc. II. Technical Parameters 1. Resolution: Resolution is an important parameter that measures the performance of a fax device. It represents the amount of detail that the device can capture and transmit in images, usually expressed in dots per inch (DPI) or dots per millimeter (DPMM). A high-resolution fax device can transmit clearer images and text. 2. Transmission Speed: Transmission speed refers to the amount of data that a fax device can transmit in a unit of time, usually measured by the time required for each page to be transmitted. A faster transmission speed means shorter waiting time for users. 3. Compatibility: Compatibility refers to the ability of a fax device to communicate with other devices and systems. Modern fax devices usually support multiple communication protocols and standards to connect and communicate with different types of devices and networks. 4. Error Rate: The error rate is an important indicator that measures the reliability of a fax device. It represents the frequency of errors or failures during transmission. A fax device with a low error rate can ensure reliability and stability in transmission.
