Laser surface treatment of metallic material, is developed over the past decade a new technology. Whether it's black metal or non-ferrous metals, in practice applications it shows a distinct superiority, and in industrial production has been widely used. Laser processing of metal, usually based on a certain mode of the laser beam aimed at the site of the workpiece to be addressed by the workpiece with table movement (rotation or translation) to achieve laser scanning. In order to prevent surface oxidation and the generation of plasma, often using an inert gas protection system, the general handling of the workpiece are air-cooled, some pieces are special requirements can be cooled by liquid nitrogen [14]. As the laser processing show a clear superiority of the quality and effectiveness, its application has been developed rapidly. The safety consideration of Laser Pointer should be included in the instruction of Laser Pointer .
Laser marking and laser materials can be divided into the role of surface marking (such as sculpture) and material conversion (such as bleach). Laser surface marking a method as earlier, it is the use of evaporation or ablation of a shallow surface to produce the desired mark. In recent years, more and more popular in the plastic sub-surface marking. This method usually add some sensitive pigment, laser photochemical change by the increase of plastic or the paint color [15]. The next century, new applications of laser technology will continue to make miracles become ordinary, laser development, history has proven this point. Laser technology will be a better person to be linked with human development, she would quietly serve and not for our lives that we perceive.Vibration method: maintenance, inspection laser printer, a "vibration check" method is very effective. Especially for older or have time for a long time, but no particularly large apparent failure of the printer. Vibration method can be varied, usually the machine or by hand to tap the beat with insulating objects, flick the circuit components, when the fault disappears when you touch a component, which can be visually determine the fault that is here. 
Many laser printer connectors, repair to remember clearly their respective positions, colors, etc., to prevent incorrect insertion when you reset, causing new problems. All wiring must be fixed according to the original position, to prevent cross-sensor electromagnetic field, causing poor print quality. Replacement of the component must be the same type of components, even substitution of components, the main parameters must be consistent, not arbitrary substitution. Laser printers and optical laser components, can not disassemble it to adjust, or will cause the laser aging, focus offset, affect the printing or font-variant. Laser printer cartridge components, can not disassemble it, can not touch the drum, but can not wipe with a solvent free, so as not to damage the photoconductive layer, the cartridge components should be stored on the dark place, avoid excessive exposure caused scrapped.
