Laser printer structure-Alice factory

November 26, 2021

The laser printer is composed of laser, acousto-optic modulator, high-frequency drive, scanner, synchronizer and optical deflector. Its function is to modulate the binary dot matrix information sent by the interface circuit on the laser beam, and then scan it to the photosensitive Physically. The photoreceptor and the camera mechanism form an electrophotographic transfer system, which transfers the image and text shot on the photoreceptor drum to the printing paper. The principle is the same as that of a copier. The laser printer is a non-impact output device that combines laser scanning technology and electronic imaging technology. It has different models and different printing functions, but the working principle is basically the same, and it has to go through seven processes: charging, exposure, developing, transfer, discharging, cleaning, and fixing, of which five processes are carried out around the photosensitive drum. . When the text or image to be printed is input into the computer, it is preprocessed by computer software. Then it is converted by the printer driver into a printing command (printer language) that the printer can recognize and sent to the high-frequency drive circuit to control the on and off of the laser transmitter to form a dot matrix laser beam, and then the electronic imaging system is displayed by the scanning mirror The photosensitive drum in the photoconductive drum performs axial scanning exposure, and the vertical scanning is realized by the rotation of the photosensitive drum itself.
