Printers used in our daily lives is essential office equipment already, and printers in the office of the universal, and the use of family life in more and more, many home users have a printer is not a luxury things, but we in daily family life in the office and use the printer, we encounter the printer does not work, or want to change how your machine durability. Then we need to know the printer, to learn some of the daily maintenance of skills. Practical maintenance skills laser printers Recent years, with the popularization of laser printer, laser printer troubleshooting has become an important issue, since many units do not have professional maintenance personnel in maintenance, there are many phenomena of misuse. Laser printer maintenance is a highly technical task that requires considerable experience and patience. Laser printer repair is a highly technical task that requires considerable experience and patience, in recent years, with the popularization of laser prin ter, laser printer, the troubleshooting has become an important issue, because many units no professional maintenance personnel in maintenance, there are many phenomena of misuse, not only did not rule out failure will damage the good parts. Laser printers according to their maintenance over the years some experience, learn from the master to learn some professional experience in maintenance skills, to talk about the laser printer repair should pay attention to some of the issues in order to start a discussion. Recent years, high-tech laser printer as the constant use, the integrated level is getting stronger, with the rapid increase of electronic control technology, laser printers will be more simple structure. Because of the circuit board with a number of integrated circuits, to the maintenance of increased difficulty and technical content. In addition, laser printers generally do not provide random data circuit drawings, and some integrated chip failure no information was available. Therefore, maintenance, inspection and control must be the correct way to determine fault. Can not blindly dismantle, so as not to expand the malfunction. In general, mid-range models above, as long as the main supply power supply is working properly, failure will show fault code, meaning code can check the corresponding fault location (such as HP, Canon, Epson, etc. in high-grade printer, working conditions have shown a "screen"). Mid-range models have adopted the following panel indicator, meaning that working conditions and failure, according to light conditions and the meaning of troubleshooting (such as HP 4L, 6L and other models). Some models also no panel lights, need to be supplied printing software installed on your computer and connection with, the computer screen will display the current working status of the screen and sound tips, check the corresponding parts of these tips. Laser printer circuit design quite perfect, it uses a multi-level protection measures and the order of switching circuits, the failure rate is very low. Therefore, when the printer fails, the first exclusion of other improper operation and materials not suitable for the problem, do not rush to dismantle the printer, first turn off main power switch, so the printer temperature down after a reboot, to see whether to clear the fault, if fault phenomenon still further repair. Because laser printers are a lot of trouble caused by a temporary error, so do so is to restart the printer by means of self-detection, error failure to restore order. Also note that many parts of laser printers, such as cartridge components, Fuser components, wheels, rub on paper consumption components are required to change regularly.
