1、激光打印机的组成及工作原理 激光打印机主要由字形发生器、激光器及光调制器、扫描多面转镜、感光鼓、显影器、转印电极、定影器和输纸机构等组成。激光器现在多用半导体激光器,它体积小,效率高。感光鼓是激光打印机的核心部件,它的表面经过充电后,可以带上静电荷。某点遇到光照射后,这点的电阻趋于零,使电荷立即消
1, the composition and working principle of laser printers Laser printers mainly by the glyph generator, laser and light modulator, scanning multi-face turn mirror, photosensitive drum, developer, transfer electrodes, fuser and feeding mechanism and other components. Lasers are now more used semiconductor lasers, it is small, high efficiency. Drum laser printer is the core component of its surface after charging, you can bring electrostatic charge. After a point of exposure to light, the resistance of this point tends to zero, so that the charge immediately eliminate
