打印机磁辊

Printing is the precursor of the modern civilization which accelerated the spread and accumulation of knowledge.印刷是现代文明的先驱，现代文明加速了知识的传播和积累。 As an important output device of the computer, printer has long been came into our daily lives, then demand for作为计算机的重要输出设备，打印机早已走进我们的日常生活，于是需求 激光打印机 磁辊总是很大。

Data will be firstly staged at the cache when computer transfer data to the printer, then processor of printer organize the block of data into the signal flow to stimulate the engine.当计算机将数据传输到打印机时，数据将首先在缓存中暂存，然后打印机的处理器将数据块组织到信号流中以刺激引擎。 For laser printer, signal flow is a set of pulse signals which power the laser head to work.对于激光打印机，信号流是一组脉冲信号，可为激光头供电。 The core technology of the laser printer is certainly electronic imaging technology.激光打印机的核心技术当然是电子成像技术。 It combines imaging and electronics to generate image, and photoreceptor drum is regarded as the most critical component.它结合了成像和电子技术以生成图像，感光鼓被认为是最关键的组件。 The laser guided by data signals falls on a prismatic reflector and light scan successively from one end to the other end as the rotation of the reflector.由数据信号引导的激光落在棱镜反射器上，随着反射器的旋转，光从一端到另一端依次扫描。 Actually, drum is an organic material coated cylinder with electric charge.实际上，鼓是带电荷的有机材料涂层圆柱体。 The electric resistance of the exposed region will decrease and charge disappear also, therefore, a latent image composed by electric charge formed on the surface of the drum.曝光区域的电阻将减小，电荷也将消失，因此，由鼓表面上形成的电荷构成的潜像。 Toner is type of charged micro plastic particles and its polarity is opposite to the surface of drum.碳粉是带电的微塑料颗粒类型，其极性与感光鼓表面相反。 Charged region will absorb toner particles when drum surface pass develops roller or magnetic roller, and thus latent image became real image.当感光鼓表面通过显影辊或磁性辊时，带电区域将吸收墨粉颗粒，因此潜像变为真实图像。 In the meanwhile, another transmission system transport printing paper to a set of electrodes, and hence give much stronger electric charge to the paper.同时，另一种传输系统将打印纸传输到一组电极，从而给纸带更多的电荷。 The toner on the surface of drum will be absorbed to the printer paper due to the same polarity.由于相同的极性，感光鼓表面上的墨粉将被吸收到打印机纸张上。 The printed paper needs a heating process to melt the toner before being sent out.打印的纸张在送出之前需要进行加热以融化碳粉的过程。

Toner is a powder mixture which composed by polypropylene resin, carbon powder, iron oxide, charge control agent, formed silica, and various minerals for triboelectrification.碳粉是一种粉末混合物，由聚丙烯树脂，碳粉，氧化铁，电荷控制剂，形成的二氧化硅和各种矿物组成，用于摩擦起电。 As one of the essential parts of the laser printer, laser printer magnetic rollers are utilized to transport toner to the drum rely on the attractive interaction between the作为激光打印机的重要组成部分之一，依靠激光打印机的磁辊之间的有吸引力的相互作用，将其用于将墨粉传输到硒鼓。 磁铁 和氧化铁。
