Typically, users only know that laser Printer Print speed, print quality and good, but understand the principles of its work and how many people? However, the printer works well for routine maintenance on the printer, thereby increasing the quality of work and life of the machine are all important . Typically, laser printers can be divided into six major systems, namely power supply system (PowerSystem), DC control system (DC controller System), interface system (FormatterSystem), laser scanning system (Laser / Scanner System), imaging system (ImageFormation System) and twist paper system (Pick-up/FeedSystem), the most important is the imaging system, the following six systems that we were on a simple set: 1, power supply system (Power System) Reap electrical current era, it seems that all machines need to use electricity, so you can say that each machine will inevitably have a power supply system (only the severity of the size of the points), the more stress on the power of the laser printer More is no exception. Laser printer power supply system is the other five systems of energy based on the merits of its performance directly affects the play the other five systems. General, laser printer power supply system is divided into three types, namely, high voltage, low voltage, direct current, high voltage so the general role of imaging system, using high voltage operation can make lasers work. Low in all the major engine to drive the motor, voltage, size can be determined according to needs, such as prominent HP6L series Ji Da, there are two 5V and 12V. The DC is used to drive DC-board sensors, control, and CPU and other chips. Three kinds of voltage isolated, its main divisions, but interact and build a stable supply system. Second, DC control system (DC controller System) DC control system is mainly used to coordinate and control the printer between the various systems, such as data receiving, scanning control unit, sensor testing, and monitoring of various DC and distribution, its circuits than the other 5 system to be complex, which contains many of electronic expertise, including amplification, feedback circuit, so I e-course examination is recommended the user does not pass or less fixed it better. Third, the interface system (Formatter System) Sent to the printer when the computer print command, the printer will not print direct response away File But first need to print the command "translate" over, and then get the true according to the command to work. In this "translation" job is working on interface system, which is between the printer and computer, a "bridge" for transmission over the computer data "translation" into the printer can identify the language. Interface systems generally include three small parts, namely, interface circuit, CPU, BIOS circuit. Interface circuit to generate regulated by the currents of chips used to protect and drive other chips. CPU is a core part of the printer board, in which the role is to act as "translator" role. BIOS circuit is the printer itself, which includes the printer itself, some of the configuration to factory information. In three parts, the interface circuit is always in contact, the maintenance of the interface system also seems to be limited to this. 4, laser scanning system (Laser / Scanner System) Laser scanning system is often referred to as laser scanning unit, which is mainly from the polygon rotating motor, light control circuit and the lens group of three parts. Mainly through high-speed rotary motor angular rotation of the multi-mirror, the laser beam by the lens to the OPC (organic photosensitive drum, also known as photosensitive drum) surface. Laser light control circuit including control circuitry and light-emitting diodes, used to generate the control over the laser beam. The lens group through the divergence of light refraction to the aggregation function of the OPC surface of the imaging work to the next step. 5, imaging system (Image Formation System) Imaging system is a laser printer is the most important system of work, their work performance has a direct impact on the quality of the output presentation. Workflow imaging system generally charging, exposure, imaging, transfer, fixing and other major steps, each step of the print quality is crucial, I think that here a simple analysis of the need to: I am an expert from steelslittingmachine.com, while we provides the quality product, such as slitting and rewinding machines Manufacturer , sheet metal slitter, sheet metal slitter,and more.
