Many curious friends have become interested in the working principle of laser printers, and want to know how laser printers print text and patterns on white paper. In fact, the principle of laser printer is not very complicated, the following small series for everyone to bring relevant introduction.
The principle of laser printers, the first thing to say is conversion. The pages, documents, etc. stored in our computer are obviously not used by the printer. They need to be converted into data that can be used by the printer. Laser printers need to convert these documents into printers at one time. Content.
After converting to a language that the printer can understand, the first thing a laser printer needs to print a page of a document is to charge the toner cartridge of the laser printer. Now it is more common to use the charging roller and the toner cartridge to touch and rotate together. Charge the surface of the drum so that the surface of the drum is filled with static charge. However, under the full state, just like the black screen of the computer, it is obviously impossible to print the pattern. This requires a fourth process - development.
On the surface of the drum filled with electric charge, the unnecessary charge is removed by laser irradiation or LED irradiation, and only the required electric charge is retained, which forms a charged latent image on the surface of the toner cartridge. At this time, the toner cartridge is in contact with the toner hopper, and the static electricity portion adsorbs the toner, and the discharged portion is blank, and the toner is not adsorbed, and an image to be printed is formed on the surface of the toner cartridge. Further down, it is the rubber wheel of the printer carton. Rolling up a piece of paper, this paper is in contact with the toner cartridge, so that the toner on the toner cartridge will be absorbed.
When the toner is adsorbed onto the paper, the rest is much simpler. On the one hand, the toner cartridge is de-energized to clean the surface of the drum. On the other hand, the paper with the toner is transported to the paper by the printer transmission mechanism. The fixing unit near the outlet, the fixing unit is used to heat the paper to a certain temperature. At this time, the wax (or colorless plastic) in the toner component will sublimate, and the pigment will be inserted into the paper fiber to form a firm pattern. So the document printed by the laser printer, just picked up and printed, will find that the paper is hot.
The above is the principle of the laser printer. The working principle of the printer is to complete the printing process through five processes of conversion, exposure, transfer, development and fixing.
