The whole process of laser printer work can be said to be charging, exposing, developing, transferring, fixing, cleaning and erasing Wait for the cycle of the seven major steps. The entire laser printing process is carried out by the action of "charging". First, the photosensitive drum is filled with negative or positive charges. The raster bitmap image data in the printing controller is converted into the laser beam information of the laser scanner, and the photosensitive drum is directed through the reflecting prism. "Exposure", the surface of the photosensitive drum forms image information that is exactly the same as the printed image represented by a positive charge, and then adsorbs […]

1. Choose copy paper correctly Laser printers are used to output paper samples, so first choose paper. It is best to choose electrostatic copy paper. The range of paper is 60-10Sg/square meter. 70g/square meter copy paper is often used. Paper that is too thin or too thick will easily cause paper jam. It may cause mechanical abrasion. It is best not to cut the paper yourself. The cut paper often has burrs and the paper lint accumulates in the machine, which will damage the machine parts and may also scratch the photosensitive drum. Before using the paper, do not put it directly in the paper box. You should make dumplings […]

The toner cartridge of the laser printer assembly plays an important role in the imaging of the laser printer, and it directly affects the blackness of the printing. Several key parts of laser drum: toner, photosensitive drum, charging roller, magnetic roller and scraper. Their corresponding roles are as follows: 1. Toner, as an attachment directly melted on the printing medium, the scientific proportion and fineness of its main components play a decisive role (black toner is available on the market); 2. The photosensitive drum is the core component of exposure imaging, and its photosensitive performance also plays a decisive role in the blackness of the printed product. There is already […]
