This kind of green laser pointeris of very good thermostability.
Laser printers generally divided into six major systems: 1, Power System (power supply system) 2, DC controller System (DC control system) 3, Formatter System (Interface Systems) 4, Laser / Scanner System (laser scanning system) 5, Image Formation System (Imaging Systems) 6, Pick-up/Feed System (paper feed system). The following will be the six major systems are described. Power supply system acting on the other five systems, as necessary, the input AC is regulated high-pressure, low-voltage, direct current. High-voltage normally applied to imaging systems, many models of printers have a separate high-voltage plate, such as HP4, HP4V, Fang Zhengwen masterpiece 280, XeroxP8E, Canon BX/BX2 and so on. But with the increasing integration of the high, a lot of printers high board, power board and the DC control board is integrated. Like HP5L/6L, HP4L/4P, HP5P/6P, HP4000, HP5000, etc. Low-voltage electric motor is mainly used to drive each engine, the voltage may be needed, as HP5L/6L are 5V, 12V voltage, and HP5000 are 3.4 \ /, 5V, 24V voltage. DC DC board is mainly used to drive various types of sensors, control chip and CPU and so on. Various types of laser printers in the models and specific to the design of a system may be different, but they work great until it is the same, but according to a local function of the design need to be enhanced. The good green laser pointercompany has the complete testing equipment of good quality so that the product quality is good enough.
DC control system is mainly used to coordinate and control the printer's work between the various systems: the system receives data from the interface, the drive control laser scanning unit, test sensors, control AC and DC distribution, over-voltage / under current protection, energy saving mode, the control high-voltage distribution. The circuit composition than the other five systems are complex, involving some of the professional knowledge of the circuit, such as amplifier, the feedback circuit, the rectifier circuit, is the maintenance of a storm. Printer and computer interface system is connected to the bridge, which is responsible for the computer to pass data over a certain format, translated into DC board can handle the format and passed to the DC board. Constitutes a general interface system has three parts: the interface circuit, CPU, BIOS circuit. In the interface circuit are mainly responsible for producing some of the current regulator chip (for the protection and drive other chips). CPU main task is to translate the interface circuit to pass over the data, control signals and passed to the DC board translated data. Some printer models, the interface circuit also made into the CPU, like HP4L/4P. This part of the main BIOS printer circuit some of the configuration itself, as well as manufacturers of some relevant information. However, some printer interface circuit of the system and no BIOS can not print printer is generally self-testers, such as Wenjie 280, Epson 5700/5800 and so on, and we usually only limited to the maintenance interface interface circuit.
