How to perform the sampling inspection of laser pointer

The probability theory is the basis of sampling inspection of laser pointer .
Most fusing roller cleaning pad is contaminated or damaged caused. Treatment: to clear the surface of the toner to the cleaning pad or clean replacement liner, you can troubleshoot. All black laser printer paper. Analysis: when the pattern appears on the regular blank dots, a general description of the performance of the paper is not good or the surface of the paper wet point and can not accept toner or dirty cause due to the transfer of the electrode wire. Processing: for the better with other performance and dry paper, or clean the inside of the printer may not transfer the electrode wire and the surrounding area. HP4L laser printer to print the right side of the paper is black. Analysis: laser printers print writing is a little pale, it usually has the following causes and solutions. The personnel of inspecting laser pointer need to know some basic knowledge. Below what is laser technology, its classification, showing the principle, its better than the other display technology, as well as the history of the development on this field at home and abroad this very future trends are described. The laser display technology and how it works. The laser display technology is the next generation display technology, following the display of black and white, standard color display and digital display is a revolution in display technology. The laser display full advantage of the laser wavelength can be selected and the characteristics of high spectral brightness laser light source, so images with greater color gamut, its color gamut coverage of up to two times the phosphor can be achieved by the human eye can identify more than 90% of the color space, and a high degree of color saturation. More details will be provided for definition of laser pointer .After the battery has been mounted in the desk charger of laser pointer
Laser TV to use a diode-pumped solid-state laser material to produce red, green, blue, three kinds of wavelength continuous wave laser light as a color laser TV, laser scanning images through the television signal to control the three primary colors. The laser display system consists of lasers, modulators, optical deflector and the screen composition. The system receives the video signal, the red, green, and blue color image signal and the frame synchronization signal from the signal separation. Treated, three-color signal control tri-color semiconductor laser diode line array, so that given the appropriate intensity of light, together color modulation output under the control of the frame synchronization signal by the optical deflector, beam scanning, hitting the receiver to form the image on the screen.
