What are the differences between red ray laser pointer and green ray laser pointer

What are the differences between red ray laser pointer and green ray laser pointer ?
The two works are the same. The models vary, transfer to different. The early production of laser printers use of the transfer corona discharge. When the toner image drum rotation and transfer the tangent to the location of the electrodes or transfer rubber rollers, a paper was sent to both, then added to the transfer electrode on the high-pressure start discharge paper to the drum at the same time, the underside of the printing paper to transfer high-voltage electric field, the toner image on the drum to attract to the print paper to complete the secondary transfer of the toner image. Transfer the discharge polarity of the electrode wire or transfer rubber rollers are the same, was negative. It is the 100mW bright laser pointer pen.
However, this negative voltage than the drum exposed areas brought negative high voltage, so that the printing paper to push the drum at the same time, also toner to maximize attracted to the print paper. But pay attention to the transfer of toner to fight that on paper, if the fight that is paper damp, poor insulation performance, it will affect the efficiency of toner transfer, hence the image defect character hollow chip of poor print quality. The difference between yellow ray laser pointer and blue ray laser pointer will be contained.
When the toner image transferred onto the print paper, the paper takes on a charge. In the process of printing paper transport, electric and friction may damage the structure of the toner image after the toner image transfer, coupled with the electrical device of a "get rid of , also known as "separation of teeth." Its role is to charge toner on the paper and adsorption and to eliminate the polarity to make it significantly neutral, physically attached to the print paper, in order to ensure the accuracy of fixing the toner image before. The process of elimination power is AC voltage, so as to achieve the best eliminate power and effect. Will print the adsorption of the toner image on paper, using pressurized hot melt method, melt the toner immersed in the paper, the formation of a fixed image of the process, known as "fixing". The table will introduce the difference between the blue ray laser pointer and green ray laser pointer .
Adsorption on paper, toner, is formed by the heat of the resin and toner mixing small particles when adsorption have the toner to the paper after the two higher gap without large metal drum caught, carbon The melted resin in the powder and the toner is tightly pressure attached to a piece of paper to form a permanent image, but also to complete the entire process of laser printing.
