So the premise of the above factors, how to control testing costs?The package of 100mW laser pointer gives people a decent impression. First make sure the object you want to test, you want to test it to confirm what kind of performance, such as when you want to test has nothing to do with the blackness of the components, with no need to ask its parts have to meet the requirements of the blackness, no need to the use of qualified production materials to do this with the test, this is your one way to reduce cost of test, especially in the development of new products, to test the wear resistance of many parts, the use of outdated and some properties of the toner is not qualified parts to complete the same task, and so the choice of too much, do not go into here, we need to work flexibly.The reason why this question here, I want to remind everyone in the daily work to strengthen the concept of costs, because the existence of our refurbished products are closely related with the costs.The package of Blue Laser Pointer gives people an elegant impression.Maintenance of laser printers to pay attention to the technical problemsLaser printer maintenance is a highly technical task, requiring considerable experience and patience, in recent years, the popularity of the application with the laser printer, laser printer troubleshooting has become an important issue, because many units do not have professional maintenance staff, there are many in the maintenance of misuse phenomenon, not only does not rule out failure will damage the good parts.The receiver of 200mW Laser Pointer can be added memory function.According to their laser printer maintenance over the years, some experience, learn from the experience of some professional maintenance of the master skills, to talk about the laser printer repair to the attention of some of the issues in order to initiate.In recent years, due to high-tech in continuous use in laser printers, printer growing degree of integration, with the rapid increase in electronic control technology, laser printers, the structure will be more simple. However, the board adopted a number of integrated circuits, to increase the difficulty of maintenance work 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, be sure to check and determine the failure to grasp the correct way. The receiver of 5mW laser pointer could be manufactured according to clients’ requirements.Dismantling can not be blind, so as not to expand the fault.In general, more mid-range models, as long as the main supply power supply is working properly, failure will show fault code, according to the meaning of the code, check the corresponding fault location (such as HP, Canon, Epson and other high-end printer, work has shown the status of the "display"). Mid-range models have adopted the following panel lights to indicate working status and failure meaning, according to the indicator status and meaning of troubleshooting (such as HP 4L, 6L and other models).Clients can decide the functions of the receiver of green laster pointer. No panel lights and some models need to be supplied print software installed on your computer and with the connection, the computer screen will display the current work status screen and voice prompts, according to the corresponding parts of these tips check.
