Green laser pointer with remote control

Resistivity is significantly reduced by the place after the exposure, the surface charge and interface charge will be in and disappear. At the same time, the photoconductor is not see light situations, good insulation properties, without exposure of the surface charge remained unchanged, namely the formation of a layer of electrostatic latent image. Scanning exposure is the use of the drum surface of the photosensitive nature of the photoconductive material. When the photoconductor by laser beam scanning exposure, the conductive layer through the light part of the drum to make the charge disappear, not by light irradiation with the remains, thus forming a potential difference of the image can also be understood as a photosensitive drum to "eliminate electrical process. The process of elimination electric potential of the photoconductor surface is changing, this potential change on the print quality impact.   laser pointer   outputs green ray with power of 80mw-100mw.
Residual potential is too high, there will be printing the "bottom ash" phenomenon. The light conductor formed on the surface of the electrostatic latent image, show after "developer", toner images, a process known as "e-developer". Developing the work is completed by the imaging device. Its role is the electrostatic latent like to become an image. Imaging is the use of the material charge same-sex exclusion, completed by the principle of opposites attract. The bunker in the blender, when toner Triboelectrification. When the toner in the bunker beater evenly, the toner in the magnetic roller, the magnetic field of permanent core adsorbed to the surface of the magnetic stick roller, magnetic roller scraper front-end-oriented to produce a concentrated magnetic field, so the concentrated magnetic field will the reagent focus to this part. Make sure that the batteries of  green laser pointer  are placed correctly.
Reagent concentrate the magnetic field because the combination of very strong with the scraper. Therefore, the basic move. This along with the rotation of the developing roller, friction between the scraper and the magnetic roller sleeve, toner surface to bring a negative electrostatic. Due to the formation the the drum Shangming Department of electrostatic latent image potential exposure in the dark is still a negative charge, negative developing bias is applied through the imaging drum, with negative potential of the toner on the developing roller imaging with a jump to the drum. Jumping toner in the formation of the the Ming Ministry of the electrostatic latent image of the drum surface. Proportional to the amount of toner attached at this time, and contrast potential. In addition, the drum surface of the dark, because of the potential of a single charge, so the toner with a negative potential will be excluded, not attached. Prices of  green laser pointer  having USB flash disks are relatively higher.
Through these processes, to form a visual image on the drum. In the magnetic roller sleeve above, plus an AC bias voltage, an AC bias voltage is applied to reduce the attractiveness of the toner with magnetic roller, the toner with the drum surface and enhance the non-exposure region repulsion. So that the AC bias voltage improvement in printing black and clarity, resolution of the problem. With a high voltage electrostatic drum surface of the toner image transfer to plain paper, this process is called "transfer". When the negatively charged toner with a negative voltage up to 500-1000V, electrostatic attraction will be the paper close to the light guide panel, go to the paper near the electrode placed in the back of the paper, put positively charged with the drum, charge of the toner is adsorbed to the surface of the paper. 90% of   green laser pointer   on market are without power switches.
Professional manner with paper insulation. When the paper and damp weather, toner leakage of the paper surface and can not be completely and tightly adsorbed on the top, which led to poor print quality, such as image defects, and character hollow exception. Adsorption of the toner image on paper, the use of pressurized hot melt method, melt the toner to invade the paper to form a fixed image of the process, known as "fixing". Adsorbed on paper, toner, mixing from small particles by the heat of the resin and toner.   green laser pointer  with remote control has done a good job in solving the inconvenience.
