Selective laser printer ZRapid iSLA550 SLA 3D printer

Different laser printers have different printing functions, but their working principles are basically the same. They all go through seven processes: charging, exposure, development, transfer printing, power elimination, cleaning, and fixing, five of which are around the photoreceptor drum. When the text or image to be printed is input into the computer, it is preprocessed by computer software. Then, the printer driver is converted into a print command (printer language) that can be recognized by the printer and sent to the high-frequency drive circuit to control the opening and closing of the laser transmitter to form a dot matrix laser beam. Then, the sensitive drum in the electronic imaging system is axially scanned and exposed through the scanning rotating mirror. The longitudinal scanning is realized by the rotation of the sensitive drum itself.

The laser printer has high voltage circuit and high temperature circuit, so the electronic radiation and thermal radiation have a certain impact on the human body. Pay attention to the protection of pregnant women and children or keep away from these devices. In the process of printing, high temperature heating will bring out some powder and ink particles, which is bad for breathing. It should be avoided to work at the laser printer for a long time.
