Another is, Sheng tray is not properly installed, poor quality paper, too thin, too thick, damp, may have resulted in the failure of a paper jam or not the pickup. Paper rules scratches. Analysis: When the printer pattern black stripes or vertical blur the toner in the paper, mostly due to the fusing roller cleaning pad was contaminated or damaged caused by the laser printer when alive. Treatment: to clear the surface of the toner to the cleaning pad or clean replacement liner, you can troubleshoot. Laser printer paper black. Analysis: When the pattern appears on the regular blank dot, and a general description of the performance of the paper is not good or the surface of the paper wet point can not accept toner or dirty due to the transfer of the electrode wire cause. It is contained in the working instruction of laser pointer .Crack control technology is an excellent shock cutting precision cutting for brittle materials. Laser powerrequired less than conventional laser evapo-rative cutting or laser drawing, cutting speed and much more. However, the above mentioned research and development efforts are limited to two dimensional slices of thin board. Processing technology, based on number of - the principle can be extended to the processing of three-dimensional molding. The laser forming technology This paper presents a three-dimensional fracture processing technology. The traditional laser processing potential of the direct processing of the complex shape of the advanced ceramic materials. Has proven that high material removal rate can be achieved. But the high temperature generated by the loss of power due to the severe materials during processing. Discussion and research of laser pointer should be carried out during the meeting.It is during the quality analysis of laser pointer.Generally not suitable for this type of material with the CO2 laser beam cutting continuous wave beam. Aluminum, copper, to form a sufficient starting power generally need the 3kW above in order to obtain the initial holes of the penetration effect. Black metal steel class materials and nickel, titanium 10.6mm CO2 beam must absorption rate, especially when the surface after heating to a certain temperature or oxide film, the absorption rate will be greatly improved, thereby to obtain better cutting effect. Opaque material, the absorption rate = (1 - albedo), and surface state, temperature and wavelength. Material the size of the absorption rate of the beam plays an important role in the heating start-up phase. laser pointer is stored well in the workshop.
