Copiers are an important category of office equipment. Because they are frequently used, they are prone to failure. To reduce the failure rate, you need to carefully understand the structure of the copier . What is the structure of the copier ? The following decoration home decoration network Xiaobian will bring you the basic structure of the copy machine for your reference. What is the basic structure of the copier? Copier structure 1, optical imaging system: mainly consists of exposure lamp, mirror (1 ~ 6 or 1 ~ 4), optical lens. Its function is to image the original onto the drum, so the image quality of the optical system directly affects the quality of the copy. Copier structure 2, photosensitive drum and imaging system: mainly composed of photosensitive drum, charging electrode, transfer electrode, separation electrode, and image-like edge-eliminating lamp and full-discharge lamp. The function is to convert the optical image imaged by the optical imaging system on the surface of the photosensitive drum into a potential latent image; then transfer the toner image on the photosensitive drum to the copy paper; then, the copy paper is smoothly peeled off from the photosensitive drum to complete the original The process of copying. Copier structure 3, developing system: mainly consists of powder adding motor, toner cartridge, developing magnetic stick, magnetic stick scraper, toner agitator, toner conveying auger and transmission gear. The function is to add the powder motor to the toner in the toner cartridge through the toner conveying screw into the developing device, and then the toner agitator fully stirs the toner to charge the toner and adsorb it on the developing magnetic rod. The thickness of the toner on the magnetic bar is controlled by the magnetic bar blade. Finally, the toner on the surface of the magnetic stick is adsorbed onto the photosensitive drum by the electric charge on the surface of the photosensitive drum to form a photosensitive toner image. Copier structure 4, paper feeding system: mainly composed of paper feeding motor, pickup roller, paper box, transmission gear. Its function is to feed the copy paper into the machine, in preparation for transferring the toner image on the drum surface to the paper for the next step. Copier structure 5, cleaning system: mainly consists of cleaning blade, recycling stick, waste powder transmission screw, waste toner box, transmission gear. The function is that the cleaning blade scrapes off the residual toner on the surface of the photosensitive drum, and then collects the waste toner into the waste toner box through the recycling stick and the waste powder transmission auger. Since it is impossible for all copiers to transfer the toner on the surface of the drum to the copy paper by transfer. Therefore, there is residual toner on the surface of the drum, and if it is not cleaned, it will affect the quality of the subsequent copies. Copier structure 6, fixing system: mainly composed of fixing hot stick, pressure stick, heating lamp, thermistor, overheat protection switch, transmission gear. Its function is to heat the heat roller to a certain temperature by heating the lamp, and the temperature value is controlled by the thermistor. Then, the toner on the copy paper is melted by the pressure between the heat stick and the pressure stick, and then fixed on the copy paper. Copier structure 7, transmission system: mainly consists of main motor, scanning lamp frame motor, lens motor, paper feed motor and development motor (the latter two copiers do not have), transmission gear, transmission chain (belt or wire rope). The main motor drives the photosensitive drum, paper feeding mechanism, cleaner, fuser, developing device and paper feeding mechanism (some models are driven by independent motors); the lens motor controls the lens to move back and forth in different proportions to ensure the effect of the copy; The motor drives the lamp holder to advance and retreat, and also ensures that the movement of the lamp holder is synchronized with the rotation of the photosensitive drum; the paper feeding motor drives the pickup roller to feed the paper into the machine; the developing motor drives the rotation of the developing device to ink The powder is delivered synchronously to the magnetic bar. Copier structure 8, paper feeding system: mainly consists of paper guide, paper feed wheel, paper belt, branch fan, paper guide. The copy paper is sent to the copier by the pickup roller to the copier and then the copier is completed. In addition to the paper feeding, transfer and fixing processes, other auxiliary processes are required, and the paper feeding system is essential for the normal transfer of the copy paper in the copying machine. section.
