It is to take up market shares of green laser pointer
Should be compared with good optical system. The optical system according to the lens in the front and rear position of the scanner, before / after two forms of the sub-objective, serious objective type in the scanning of large graphics distortion, rarely used. Objective before scanning lines than straight, but some distortion due to the later production of laser printers, the use of multiple lenses together wide-angle focusing mirror, a focal length of 300mm, multi-faceted rotating mirror, object distance is 37mm, distortion only 0.0011%, has been able to fully meet the requirements of the laser imaging. Laser printers with multi-row scanner (Mirror), generally there are two mirror, four lens, six lens three kinds, driven by the scanning motor rotation, complete horizontal scanning motion. To ensure the accuracy of led flash light parts.
It is based on the real productivity ability of green laser pointer
Positive and negative voltage is determined by the voltage of the tungsten brought the photoconductive material for selenium tellurium alloys, the charge of positively charged, the rotation of the drum after a week so that the whole surface are charging. Charge of the drum, the laser printer specific charging method because of the different models have different, but the charging principle is basically the same, are based on the charge of the DC high voltage corona discharge on the surface of the drum. The laser printer of the early production of the composite structure of the electrode wire and grid charging more, most of the new laser printer charge Cots (FCR) to charge the drum. When a high-voltage high-voltage generator to the electrode wire, the formation of a strong electric field between the wire electrode and the grid, and the release of the corona.
then make the practical sales plan of led flash light
The remaining residual potential high and low will affect the print quality, such as the residual potential is too high, will print "bottom ash" phenomenon. An electrostatic potential, like the formation, must be as follows "developing" process can be converted into a toner image. Imaging of laser printers. Photoconductor surface formed by electrostatic latent image, show after "developer", toner image, a process known as "e-developer". Developing the work is completed by the imaging device, the role of the electrostatic latent image into a visible image. Imaging is the use of material charge sex repulsion between the principle of opposites attract completed green laser led . Imaging device is equipped with iron and toner, and rubbing iron positively charged toner negatively charged.
