The standard working voltage of this kind of battery of green laser pointer

The standard working voltage of this kind of battery of green laser pointer is 3.0V
In addition, the contamination of the electrode wire or displacement can also cause this fault, it is necessary to clean or correct electrode wire. If the above checks are intact, then the fault may occur in the scanning component within the high-frequency laser driving circuit or logic circuit, you should check the scan logic circuit is damaged, you should replace the scanning components. Sometimes due to a printer with multiple computers linked to the signal line often plug. green laser pointer also has the star effect with a very special laser head.
Leaving the signal line is damaged or the plug is not strong, resulting in some of the signal can not be passed, will cause the output of all black sample failure at this time, so check the can first check the signal line is intact and plugged to avoid unnecessary maintenance. First observation of the output sample of the Black Belt was fuzzy like, if it is, clean or replace the drum scraper. If not, check the drum longitudinal scratch traces, if so, then check whether the photosensitive drum scraper local damage, in general, have a vertical black line in the output sample, the drum longitudinal a more visible scratches, which can only replace the drum, but should also carefully check the cleaning blade is beneficial to stick objects or damage.
His idea of "laser can be more accurately and quickly than any ordinary white electrostatic copier drum-shaped cylinder depicts the image." Unfortunately, his great idea and not the immediate supervisor agree, he was dubbed "traitor" in the title. In the next few years, Gary had to step by step to do experiments, but he did not give up the love of the laser cause. In this prospect seems bleak days, Gary did not give up the dream. He idea: like the pulse of radio sound waves or telephone lines, the beam is so precise that it can regulate it to transmit information. If people can control beam and use it to reliably transmit digital information, digital information is translated into a mark printed on white paper, then this miracle can make the ideas and images in the machine passed to the paper. green laser pointer can easily points at the star.In view of the laser printer is now very extensive, but most users exclude maintenance and fault are not very good at many of its peers can better understand and use the laser printer, I think in the years of use, fully understand the nature of the laser printer understanding of the structure and working principle is of great help for the exclusion of the failure of the laser printer. Therefore, will the structure of the laser printer, principles are summarized below for reference colleagues.
