The customer can use green laser pointer in some special locations for some specific purposes
Other devices in the network can be shared. In 1993, the world's first Chinese laser printer - Legend of the Chinese laser printer LJ3A officially on the market in July 1993, Lenovo's first generation of commercially available laser printer LJ3A by the Chinese Academy of Sciences, the organization's new product identification. Lexmark 1996 EXCIMER argon (ARGON) / fluorine (FLUMRINE) laser cutting technology introduced world's first 1200 x 1200dpi super high-resolution color inkjet printer the Lexmark CJ7000, the production cost of the inkjet head is only half of the other way, creating a low-cost high-quality market leader. It means the green green laser pointer needs a little time for preheating.
May 1997, the HP LaserJet 6L debut in China, which is HP specifically for the Chinese market and the introduction of laser printers. Progress on the U-shaped paper path the 6L footprint is very small, very suitable for use in a crowded desktop and home office. The price of less than 4000 yuan, declaring that the Chinese laser printing popularized the era. If HP LaserJet 4LC All fired the first shot of the HP laser printers in the popularity of the Battle of the HP LaserJet 6L lit the fuse of the Chinese laser printer market to grow explosively. 1998, HP introduced the HP Color LaserJet 4500 and 8500, the world's first color laser printer supports automatic duplex printing. It is 18650 type battery used by green laser .
The HP Color LaserJet 8500, a resolution of 600dpi, the print speed of 24ppm, built-in 45 kinds of HP FontSmart 136 proportional fonts the Adobe PostScriptType1 proportional font, built-in Truetype conversion engine. Laser printers. Overview of laser printers. The basic structure of the laser printer consists of lasers, acousto-optic modulator, high-frequency drive, scanner, synchronizer and light deflection, etc., whose role is the modulation of the binary lattice information sent by the interface circuit on the laser beam, after scanning to the photosensitive body. Electrophotographic photosensitive body composition and camera bodies transfer system, hitting the drum on the graphic image transfer to the print paper, the principle is the same with the copier. The laser printer is a combination of laser scanning technology and electronic imaging technology to non-hit output device. Here will introduce a type of battery used by green laser pointer .
Its different models, the print function is also different, but the work is basically the same principle, must go through: charging, exposure, development, transfer, consumer electrical, cleaning, fixing seven processes, of which there are five process is carried out around the drum . When you want to print text or images into the computer, computer software preprocessing. Then converted by the printer driver to the printer recognizes the print command (printer language) to the high-frequency drive circuit to control the laser transmitter on and off, the formation of the lattice laser beam by scanning rotating mirror on the electronic imaging system drum in the axial scanning exposure to achieve vertical scanning by the drum itself rotating. 18 means that the diameter of the battery of laser pointer is 18mm.
The drum is a photosensitive device, the photoconductive properties. The surface of the photoconductive coating before scanning exposure by the uniform charge on the charge of the charging roller. When the laser beam to the lattice form of fire to the photosensitive drum, the point being scanned exposure conduction, charge promptly released by the conductive base. Does not want exposed points remained of the original charge, so that the surface of the drum for the formation of a potential difference of the latent image (electrostatic latent image), when the drum rotation with the electrostatic latent image to the location of the toner magnetic roller the oppositely charged toner is adsorbed onto the drum surface to form a toner image. When the toner image drum continues to rotate, to reach the image transfer device, a paper was sent to the middle of the drum and the image transfer device. The positive pole of the battery of green laser pointer adopts the material of LCO.
