The size of this kind of green laser pointer is 20*137mm

The thermistor and the thermal switch and the heating roller near the parts, early laser printers installed in the heat roller near the center of the later improvements are installed in the heated rollers of two, these two parts is usually no need to maintain a large printer, but in a longer period of time (larger) output, thermistor on the shell (outer shell) to glue Feifen and some of the dirt, its temperature sensing, hot roll Wen Fasheng sense changes, so that the heating roller surface temperature to increase, the first hot roll life, accelerated aging and separation claws and other parts wear, and increase the warm-up time of the rubber roller, so that the fixing lamp service life decreases. Distance of remote control of  green laser pointer  is about 15m.
Secondly, the temperature is too high will make the paper curl affect the output, resulting in paper jams sulfuric acid paper, coated paper, etc., and sometimes even cause blistering and can not be used. Serious cases, even make the heating roller burned. Maintenance is to be careful to remove the fuser, remove the thermistor and the thermal switch with a cotton dipped in some alcohol to wipe clean the dirt of their shell, the operation must be careful not to shell damage. Then carefully replace the fitted must pay attention to the distance of the thermistor and the heat roller, so that the temperature is too high the damaged parts. In general, you want to thermistor as exposure to try to be the heated rollers, thermal switch may be appropriate to open space some distance. More details of  green laser pointer  will be given in the list.
Maintenance of photoelectric sensors. The photoelectric sensor is contaminated, cause the printer detection failure. Such as manual feed sensor is contaminated, the printer control system is not detected, no signal of the paper, the manual feed function will fail. And should therefore spend related to the sensor surface wipe clean with cotton wool, so that they remain clean, and always have the sensor sensitivity. Maintenance of the cartridge. Laser printer cartridges for silicone photoconductor, work fatigue, therefore, the continuous working time not too long, output can be stopped after work for some time to break for a while and then continues to output. Some users use two cartridges to work, but also a way. The power of  green laser pointer  is 5mw-10mw.
As for the cartridge maintenance and maintenance, general: Carefully remove the cartridge components, wipe clean the surface with a cotton flower, but not force, prevent the drum surface scratches. Flowers with cotton wool dipped in toner cartridges for cleaning agents to wipe the surface of the drum. Cleaning should be circled to spiral method, polished cotton flower immediately after cleaning wipe. Gently tap on the drum surface with the gauze with talc layer of talcum powder, can be loaded back to use. Usually pay attention to when replacing the toner waste toner waste toner compartment clean so as not to affect the output results. First arise because the Feifen accumulation of too much powder leakage "phenomenon, ie, the output of the comp (usually vertical) irregular black spots, black block. 3 pieces of button cell batteries is needed for  green laser .
