In the brother laser printer, the brother toner cartridge is a key part of it, and the quality of the print is directly related to the quality of the toner cartridge. The portion of the heat roller in the drum is also referred to as a fuser. Its function is to bake the toner on the paper output from the laser printer, then let the paper absorb and fix the toner on the paper, so that the original image, picture and other images generated on the paper are fixed. It is called a fuser. The hot roll is made of aluminum alloy and is coated with a special layer on the surface. It not only can withstand high temperature, but most importantly it does not stick to toner and other dirt, whether solid or molten. Therefore, the toner on the carrier (such as paper, sulfuric acid paper, etc.) can be baked and melted. Its heat source is a special far-infrared tube in the center of the heat roller. When the laser printer is warmed up (about 2 minutes) the temperature of the surface of the heat roller reaches 100 degrees, and the temperature is fixed here. Position, after the current paper in the work is fed into the fuser. The lamp of the heat roller is turned on to melt the toner, and is not heated when no paper enters, so it can be guaranteed not to exceed the pre-predetermined temperature range.
The hot roller is also a relatively easy to damage accessory in normal work. The damage is mainly the special coating on the surface. Once worn, the toner or dirt will stick to it. For example, the brothers hot-selling cartridge model brother tn310 toner, Therefore, the word or figure on the output sample lacks lines, and a black block is stuck in other blank places, which may be barely used for general manuscripts, and sulfuric acid which is required for printing is higher. For paper, it can't be used. In this sense, the daily maintenance of the heat roller is mainly to protect the coating on the surface from damage.
