How does a latent image become an image that is actually printed?
From the survey data, many people will buy brother tn450 , Actually many of them do not know the relationship between the cartridge and the laser printer, so they also do not know how the latent image become an image that is actually printed. Actually it is not difficult question, and we can learn it today.
Toner plays a crucial role. The brother toner is essentially a charged, fine plastic particle whose charge is opposite to the polarity of the charge on the surface of the toner cartridge. When the surface of the charged toner cartridge passes the applicator roller, the charged Parts of the adsorption of toner particles, the latent image becomes a real image. At the same time that the drum is rotating, another set of the drive system feeds the printing paper with the same polarity but a much stronger electric charge on the printing drum, and then the paper passes through the drum with the toner, and the toner on the drum is attracted Above the paper, the image is formed on the surface of the paper. At this point, the toner and the printer are merely held together by the attractive force of the charge. The plasticized toner is melted and heated to the surface of the paper during cooling, prior to being fed out of the printer.
After the toner is attached to the paper, the drum surface continues to rotate, passing a cleaner that removes the remaining toner to go to the next printing cycle. Visible, in this process cartridge occupies a very important position.In fact, the cartridge is the most critical part of a laser printer. Because it not only determines the print quality is good or bad, but also determines the printing costs. This is because in the laser printer, more than 70% of the imaging components are concentrated in the cartridge, print quality is actually good or bad is largely determined by the cartridge. The toner cartridge and belong to the consumables in the printer, use a period of time and reach a certain number of sheets after the need to be replaced, so choose a suitable laser printer cartridge there are many learned.
