Today we will discuss the Brother series laser printer. Of course the printer cartridge is essential point for printer. Except to maintain the printer cartridge, how to use it fully is also a very important question.

About the Brother series laser printer, because of having superior printing performance and convenient operation performance, there are a considerable number of users in the community. However, due to its expensive supplies and its use of the cartridge is very easy to fatigue, when it is tired, the cartridge surface can not be de-energized, the print media will leave a very "heavy" background color, a direct impact on the printing effect .Although the foregoing also mentions that rubbing the toner cartridge with chromium oxide can eliminate the fatigue of the toner cartridge, this method may not be feasible. Because chromium oxide is solid (insoluble), it can damage the drum surface when it is used to wipe the drum surface. Some friends tried this method, but no effect, and the cartridge surface damage is very serious. After many tests, we also found a very simple way to eliminate the phenomenon of fatigue on the surface of the drum, with this method, brother tn660 toner cartridge can print more than fifteen thousand copies of the manuscript.

For laser printer, it needs to transfer toner from the drum to the paper when printing (at this time, the tn660 toner attached to the paper is also solid particles), and then, with toner information paper And then the toner and the paper are heated by the upper heating roller of the fixing member and the fixing member, and the toner and the paper are heated and the temperature rises abruptly. The toner particles are rapidly melted and heated and heated Pressure roller squeeze, combined with the paper. The combination of toner and paper is in fact the toner penetrates the paper fibers and firmly binds to the paper fibers, which has the ability of the paper to absorb the molten toner, which interacts with the pores of the paper and the penetration of the molten tn420 into the paper , And the size and distribution of paper pores determine the density of the paper, usually speaking, "paper density" refers to the paper fiber density and thickness of the degree, also the size of the capillary, for print quality, the following two points:

(1) If the paper fiber distribution is too loose or paper fiber is too large, the capillary is relatively large, the paper density is small, a large number of molten toner into the paper inside the pores, replacing the air part of the paper pores, causing paper The scattering capacity of the paper is reduced, the transparency of the paper is reduced, the transparency is increased, and the occurrence of the offset phenomenon can easily occur. Once the offset is printed, the detail expression is deteriorated and the image resolution is reduced, and the paper It is easy to produce hair, dust, pollution of the cartridge, resulting in print defects, but also dirty the printer, especially after the optical part of the pollution, easy to cause the printed goods to produce bottom ash;
