laser pointer possesses the function of the laser pen

 laser pointer possesses the function of the laser pen.
China's welding technical level already has enough support. Another device is small in size, weight, torch handheld grasp, which makes it more flexible and convenient to use auxiliary tooling are cheap. The first pre-treatment is simple: just rust decontamination to fatigue layer can be. The powder feeding: argon powder feeding to send points that require low precision, you can have a certain inclination. This allows for manual operation, and more suitable for metal repair. The third micro-beam and other plasma stability: the stability of the micro-plasma and molten pool formation is also easy to control, dressing and body fusion, regional over-good. The customer can use laser pointer to highlight and point at the key item.
Fourth heating and cooling rate is lower than the laser: the molten state to maintain for a long time, uniform formation of the microstructure, better exhaust scum, powder spray process has been heated, and the protection of argon ion gas Therefore, the cladding layer uniformity better, pores, slag defects less. Material selection: ion heating on the material are less restrictive, more extensive choice of materials, carbide, oxide cladding easier. With regard to the cladding. Welding stress: We must build a concept, regardless of what kind of noun (such as welding and surfacing ? Spray ? cladding) in the heating, cast in metal matrix. laser pointer has the brilliant remote control function.
Then heated to the casting, and then cooling the process is bound to cause stress. In addition to a very special material, the general impact or contraction stress, a different way of welding, is that different from the speed of the heating mode, the filling material and other conditions. Then reduce the stress on the matrix and the cast layer, we pursue the important aspects to consider when welding quality. I think that shrinkage stress can not be avoided, then the stress release is the key to solve the welding stress. Means that the shrinkage stress release where the distribution of regional stress from the body to cast, what we need and can solve the problem. laser pointer is also the related products of multifunctional projecting equipments.
Why laser welding (cladding) deformation is small: The main cast region, the transition zone is small, a small amount of shrinkage. Then the force of contraction of the material in the contraction process, not enough to make the deformation of the entire body. This is the reason of the so-called laser cladding invariance (when body size is too small will produce the same deformation) of the laser welding (cladding) advantage. This welding stress gone? It is mainly released into the casting region and transition region. Then this raises two questions.

It is because the green laser beam light of laser pointer

Application of all these technologies to ensure the stability and accuracy of the image quality, to meet the need for diagnostic imaging. Dry laser camera film from top to bottom is divided into five layers: a protective layer; sensible heat layer; piece grass-roots level; UV absorption layer; matt layer of photosensitive material is an emulsion contains micro-capsules and the chromogenic reagent material by adhesive spread support in the film body. Some summary should be recorded for laser pointer .
Through the thermal head heating, micro-capsules permeability, reagent into the capsule and then back into the non-permeability and stop the hair color reaction, the above took place after the formation of visible images. Form an image of the color reagent was isolated by micro-capsule, making the photo imaging after long-term preservation of this thermal reaction and micro-capsule technology known as micro-isolation technology. In order to obtain stable, high-quality images using a grayscale adjustment, shade adjustment technology and gloss adjustment. The gray scale adjustment technology uses two initial temperature of the hair color (capsule wall carbon particles (Tg), as well as the micro-capsules of different sizes to optimize the combination), get a good gray scale characteristics. laser pointer has to face some design problems.
Shade adjustment technology to change the high tones of carbon particles (Tg) the shade of the wall of capsule wall, and low tones of carbon particles (Tg) by mixing six kinds of hair color agent, to obtain from the continuity of the high-light to dark shades of light, one of the black agents to adjust photos of black degree, the same black and silver film. Gloss adjustment technology backing layer uV absorbent capsule internal scattering dull material to optimize the particle size and usage.

If the bias point close to the curve at the bottom of the wave part, will cause severe nonlinear distortion. Broadband modulation to the laser modulation circuit to maintain the input current waveform is not only important to circuit design, circuit technology is equally important, because the stray inductance and stray capacitance to give the high frequency component adversely affect, to some extent will also affect the optical transmitter nonlinear distortion indicators. Laser protection circuit. The semiconductor laser is an expensive device, and protected from damage should be noted that in practical circuit applications in the optical transmitter is very important to the protection of the laser, but it still belongs to the auxiliary circuit of the optical transmitter. Also, the customer needs to consider the location situation or condition of the occasion of laser pointer .
The protective measures of the laser source requirements should be: First, reliable and is simple, does not affect the light work properly. Protect the laser is not damaged points to prevent acute damage and prevent long-term chronic damage. LD is short-term protection. The short-term acute damage to the main factors of laser overcurrent and instantaneous impact, and thus the short-term protection measures laser main boot delay protection and current limit protection. Boot delay protection is to prevent the moment of the optical transmitter power in the boot, due to damage to the circuit caused by the overshoot may be caused by the laser; boot delay Protection Act laser DC bias current delay access law and the DC bias current and modulation current of the laser delay to protect the French. The color of the laser beam light of laser pointer should also be stated clearly.
From the protective effect, the latter is simple and practical point of view, the former than the latter. Laser DC bias current-limiting protection law, there are two: First, the resistor current limiting protection law, diversion protection law. Measures and technologies used by various manufacturers are not consistent, but the effectiveness of play should be consistent, that is, must ensure that the optical transmitter power, must wait for the laser driver circuit in the DC bias and modulation current conditions into a stable state, the temperature control circuit into a stable state after a slow increase in the laser DC bias current and modulation current into the normal working state.

Green ray laser pointer refer to the pens which send green laser beam

Green ray laser pointer refer to the pens which send green laser beam.
The so-called holographic, laser technology is used in photography, film, on record in all the optical information objects, rather than ordinary photographic record of the object is only a side projection. So when the object to reproduce on film, in the eyes of the viewer was extremely realistic, it produces visual effects, real time viewing entirely and exactly the same. Holographic principle, simply put, the main advantage of this feature pure color laser. In fact, early on the theory of holography in 1947 by the British scientist Jia Boti out. Expected end of this century, but also generation of film and television; to time, people's cultural and recreational life, may be due to three-dimensional laser panoramic three-dimensional television movies and the emergence of the laser has become more colorful. laser pointer will be your best partner.
Holographic Another important application is made to replace the glass in some special occasions, holographic optical elements. This special processing of optical components with convenient, compact, light, thin and so on. A concave lens can make the beam divergence, according to a bunch of parallel light up into a spherical wave; we talked about earlier with the small particles will be captured hologram reference beam of parallel light into a spherical wave; such a hologram is a special the concave lens. A similar method can be used to produce convex, cylindrical lens and other optical components. Such components and paper-thin, as light, but also not broken. Is now useful for holographic optical elements made of the telescope, its thickness and the general myopic lenses similar. laser pointer is also called mini-laser pointers.
Also reported using holographic optical elements made of windows. Windows will not affect this strange person's attention, but it can reflect a lot of sunlight, the function of both curtains; more interesting is that it can be installed to focus the reflected sunlight in the window under the eaves of a row of solar cells , converted into electrical energy for indoor use, is really threefold. Holographic technology discerning ability. Because the hologram can be taken to accurately reproduce the original object, we can use it as the standard has not changed the original check; in fact change as long as 1 micron, you can check out using holographic technology. Research and production departments, but also so that the laser holography to the intrinsic quality of the finished product as "inspectors." It is the 200mW chargeable green ray laser pointer .
Inspection, things to be seized with a little pressure, or add a little hot; if there are cracks within the body, porous, its surface will change accordingly. Although the extent of this change is very subtle to the naked eye can not perceive, but which in holography, "eyes" Now, all these flaws, problems, all exposed. In addition to this method to check the precision inherent quality, as well as on the intact material were seized the advantages, especially for expensive items such as precious relics, the detection of ancient sculpture.

The laser beam of laser pointer is stable enough

The laser beam of laser pointer is stable enough. Laser radar and aircraft avionics systems, displays, user interfaces interface. 1995 C-141 aircraft with the first wind lidar flight test, followed by C-130 aircraft on the second and third test flight laser radar. Allegedly, operational use laser radar hardware needs to be small, can improve the accuracy of air-dropped more than 2 times. Gusts to ease the current system to the aircraft fuselage mounted accelerometer-based, performance is limited. Effective system requires aircraft turbulence encounters with turbulence before the measurement. Lidar turbulent gusts ability for future military and civilian aircraft to provide better gusts to ease system.

The family would like to buy some products of laser pointer

 The family would like to buy some products of laser pointer for the party show.
Because using a PostScript printer on the print controller's demands are high, the other Adobe PostScript is a registered product, printer manufacturers use in their products to pay for Adobe's PostScript language, a fee paid to PC makers like Microsoft's operating system costs the same, so the cost of using the PostScript printer language and the use of other than the printer control mode is higher. So now there have been some PostScript emulation, as some of HP's laser printers use PostScript emulation, can be fully compatible with Adobe's PostScript, Adobe is also no longer need to pay the appropriate fees. The party spot looks more mysterious with the decoration of laser pointer .To improve the stability of the process, the semiconductor laser in a closed loop in the (closed loop) through the heat meter, as much as possible to control and reduce the weld heat input (see Figure 1). In automated production process can be repeated to achieve high-volume production, but also improve efficiency and achieve a high optical efficiency. In most cases, the above mentioned pyrometer is integrated into the laser processing head, its detection range of static through the laser focus adjustment. Galvo scanner and pyrometer temperature control with real-time axis reflects the advantage of flexibility, and materials processing to achieve the best possible process control. The size of a single solar cell processing region through its optical properties corresponding to the description, and makes fast, flexible, temperature-controlled electrical connection of solar cells can be achieved. Laser welding characteristics: laser welding with melting pool cleaning effect, would be pure weld metal, for the same or different material, thickness of metal between the welding of high melting point, high reflectivity, high thermal conductivity and physical properties vary greatly metal welding in particular.

The technical problem tackling of laser pointer

The technical problem tackling of laser pointer has achieved a good result.
Through this introduction, powerful confocal microscope has been evident. And other biological technologies (such as immunohistochemistry, in situ hybridization, etc.) match, to further expand its detection range. We use confocal microscopy almost qualitative and quantitative detection of intracellular biochemical composition of any one. Confocal laser scanning microscopy (Confocal laser scanning microscopy) is a high-resolution micro-imaging technology. The quality of laser pointer has been improved more after the technical problem was tackled.
Laser technology is the early 1960s, developed a high-tech, after 40 years of development, from the mechanism of theory, experimental methods to the manufacturing process have gradually matured, the attention by the major military power, the future of military technology is expected to become the most an active area. Important feature of the laser are as follows: high brightness. Laser surface brightness brighter than the sun than ten billion times, this is an ordinary high-brightness light source can not be compared. This kind of laser pointer is the multifunctional type.
Strong directional. Laser emission is almost ideal parallel light beam, it can spread very far and very little divergence, the laser beam a distance of 20 kilometers, almost no divergence, the laser fired at the moon, not the spot to 2 km. People took advantage of this characteristic, accurately measure the distance between the Moon and Earth (384,000 km). Color is good. Different colors, are essentially different wavelengths of light, ordinary light source has a wavelength range of the human eye can sense wavelength is 3800 ~ 7600 angstroms, and a very narrow range of laser wavelength. Monochromatic laser light source spectrum is generally narrower than the times to a million times, is the world's best monochromatic light source. This kind of laser pointer has multiple functions.
Coherence is good. Monochromatic laser is almost ideal, is a good coherent light. The variety of natural and artificial light in space and time is messy, unrelated non-coherent light. As the laser with the above characteristics, the field of laser technology in the military is widely used. The main applications are: laser weapons for anti-enemy heavy weapons and equipment, you need a high energy, high-energy laser weapons or commonly known as laser guns. The U.S. has developed airborne laser gun and car. The powerful laser cannons, hit rate is very high.

Remote control laser pointer is low in price

Remote control  laser pointer is low in price.
Calibration can be used in two modes: "proportional Calibration" and "full calibration." Calibration mode is the default ratio calibration. In this mode, the instrument was based on concentration measurements and to provide the calibration constants for scaling. For the gas parameters and signal quality are no special requirements. For users, whenever it seems necessary to measure the instrument should be adjusted, should activate the proportion of calibration. For example, in the process gas during the measurement. Please note the following points: all the gas can be individually calibrated. In this case, for each gas fill in the correct value. For no calibration gas, the correct value is set to a negative value (eg -1). Automatic calibration gas is also possible. Enter the correct value when A is the calibration gas. Remote control laser pointer is fast in shipping.
When the correct value to zero when B is automatically calibrated. In this case, the gas absorption line B amplitude and width of the calibration constants will be adjusted according to the calibration gas A. In the above example, CO gas is calibrated to 3.5%. The corresponding calibration constants of CO2 will be adjusted, and these will not change for the H2O. To confirm the initial calibration input value. Press to upgrade to a new instrument calibration. The instrument will use the current average concentration measured to perform all necessary operations. The new calibration will be permanently stored. Calibration time will be automatically updated. NEOM using proven gas calibration in a controlled environment all the instruments. Then calibrated to the specified temperature and pressure ranges have been verified. When the receiver is not necessary to calibrate the instrument. However, if the measured concentration and the expectations do not match, the user may want to calibrate instruments directly in the process.
O2 laser gas analyzer can be used dry gas testing and calibration. Because the calibration of the instrument will affect all subsequent measurements, the user must accurately verify a new calibration. If the instrument reading at the recommended level has shown that low concentrations within the range of deviation from normal is less than 2 - 3%, we do not recommend calibration. For calibration gas mixtures, in this context is absolutely accurate. You should also laser gas analyzer accuracy to make a satisfactory explanation, it is about 1% of measured value.

The dye laser material is the organic dye solution

For the customer to determine and judge whether Laser Pointer is good enough. 
Dye molecule level. The dye laser material is the organic dye solution. Each dye molecules are composed of many atoms, the energy level structure is very complex. Electronic movement, the movement of the dye molecules, including the composition of the dye molecules, the relative vibration between atoms and the rotation of the dye molecules, so the energy levels of the dye molecules, corresponding to each electronic energy level has a set of vibration of a rotational energy levels, and molecular collisions and electrostatic disturbances, vibration - rotational energy levels are broadened. Therefore, the dye molecules the energy level diagram of Figure (5-17) shows the quasi-continuous state level structure. Singlet and triplet two types of electron energy levels in the triplet state is slightly lower than the corresponding single-state level. It utilizes the advanced and perfect production method of Laser Pointer .

The distinction, according to the workings of a pulsed pump and continuous pump; in accordance with the pump source to distinguish between the flashlamp-pumped and laser-pumped. Only describes the pulse pumping. Pulse pumping power to the pump high enough and fast enough rise time, overcome the triplet to achieve laser operation. Characteristics of such devices is the high peak power of output laser devices of high conversion efficiency and simple structure, easy to operate. Flash pulse pump. Pumped with a flash, there are two structures, ordinary straight tube and coaxial type. Straight tubular flashlamp-pumped dye laser structure similar to the solid-state lasers. The manufacturer should try the best to improve the design and technology of Laser Pointer .
Flashlamp-pumped mode structure is simple, cheap, but the pump pulse wider (typically 10-4 to to ? 10-6 seconds), the triplet can not be completely eliminated, they must also add a quencher dye.
Figure (5-20) is a grating reflector tuning cavity grating G1 is placed in the cavity in the beam expander and dispersion effects. Different wavelengths of the G1 is a diffraction relative reflectance mirror R2 for different incidence angles. Thus, when the angle of incidence of a particular wavelength of rotation R2 is zero, the wavelength of light will be able to low-loss to return to the cavity, the formation of oscillation. Therefore, rotation R2 will play a tuning role. Grating - mirror tuning cavity. Figure (5-21) is a folding-pumped dye laser schematic diagram of the cavity to place the prism dispersive element. Prism dispersion characteristics of the pump light coupled into the cavity formed coaxial pump in the form and flow with the dye.

the laser must have a wider range of applications

In the near future, the laser must have a wider range of applications. The laser weapon is a directional emission of the laser beam directly damage the target, or the failure of directed energy weapons. Depending on the operational use, the laser weapons can be divided into two major categories of tactical laser weapons and strategic laser weapons. Weapon system by the laser and tracking, targeting, launchers and other components, the commonly used laser chemical lasers, solid-state lasers, CO2 lasers. Other characteristics of the laser: laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use.The picture above shows the basic principle of laser forming: laser metal forming using metal powder as a filler, metal powder through a powder nozzle was sent to the molten pool created by the laser beam. Three-dimensional optical modeling techniques (SLA). SLA technology, also known as light-curing rapid prototyping technology, the principle is the computer-controlled laser beam on the surface of photosensitive resin as raw material point by point scanning, scanning area (approximately tenths of millimeters) thin layer of resin and curing light polymerization form parts of a thin layer.
Nitrogen processing room to ensure the security of the sintering process, the high cost of processing. The process to produce toxic gases, pollute the environment. Laser cladding forming (LCF). Laser cladding, also known as laser cladding or laser cladding, the rise in the 1970s with the development of high-power lasers, a new surface modification technology. Surface of the alloy powder or ceramic powder with the base body in the role of the laser beam rapid heating and melting, the beam away since the shock cooling the formation of the dilution rate is very low, and substrate material was metallurgical bonding surface coating, significantly improve the substrate surface resistance wear, corrosion, heat-resistant, anti-oxidation and electrical characteristics of a surface hardening method.
Only need to scan the laser beam and cutting edge of each layer, but do not have to like the SLA technology to scan the entire surface layer. The device uses a special roller paper, the connection of the paper is heated by the heating roller, then use the laser to cut the paper, the heating roller automatically leave the paper by a laser cut into level requirements of shape. The most commonly used foil is a one surface coated with a hot melt resin adhesive paper. In the the LOM molding machine, the foil was pulled out by a feeding reel, plastic face down through the modeling platform formation received in the other rewinding reel rolled up. The worker is in charge of the manufacture of green laser pointer .

The diamond film is currently a hot topic

The purchase manager of laser pointer is about to go to Guangdong to purchase samples of laser pointer .
Currently, the U.S. has been able to synthesize two carat diamond, about 5 to 6mm size. However, harsh growing conditions, long period, its cost is also expensive than natural diamond. The diamond film is currently a hot topic. Artificial diamond films primarily use its mechanical properties, the optical and electrical properties is not yet well developed. In the electrical properties of diamond films of p-type doping has already achieved, according to the latest reports, the Japanese scientists through the incorporation of sulfur has the n-type doping of the diamond. This type of laser pointer has multiple functions so that it will be a bit more expensive.
Preparation of the intraocular lens is actually composed of crystals of the primitives (atoms, molecules or ions) dissociation after their portfolio. There are three categories in accordance with the crystal group decomposition different from the means of artificial Crystals. Solution method - the crystal raw material dissolved in the solution, specifically containing aqueous solution method, hydrothermal method and flux method. Aqueous solution crystal growth at atmospheric pressure and temperature is about eighty or ninety degrees Celsius; hydrothermal method at high temperature growth; flux rule is in the atmospheric pressure high temperature crystal growth. Melting - the crystal raw material melted completely, contains the Czochralski method, the crucible relative movement method, zone melting, the base, the cold crucible with the flame fusion method.
Flame fusion method, also known as the Verneuil method, invented in 1890 by French scientists Verneuil for the growth of artificial gems. The following figure shows the growth of flame fusion method the gem device schematic. Powder raw materials, feed hammer periodically beat hopper powder from the hopper gradually fall down, fall into the position 6, Entrance 4 and Entrance into hydrogen oxygen to form a hydrogen-oxygen flame, the powder melting . Melt fell into the seed crystal growth occurs, the seed to drop slowly, slowly growing crystal. Use this method to grow crystals of up to 1m. The price advantage of laser pointer also plays an important role. 
Produced by the piezoelectric crystal resonator used in the transmitters, has appeared in the First World War, is widely used during World War II, it created a new era of modern communications. The success of the single crystal silicon and integration technologies, the human into the swing of the modern computer age. Computer's processing speed faster and faster, and there will be a quantum computer, and photonic computer using the computer of a new computing approach, but the monocrystalline silicon, but no doubt a major contribution to the computer.

It is concerning about the star gazing with Laser Pointer

It is concerning about the star gazing with Laser Pointer .
The small size of the semiconductor laser, light weight, low cost, wavelength selectable, and its application throughout the clinical, manufacturing, military, particularly among the most outstanding progress made by the high-power semiconductor laser semiconductor laser works. Laser to produce the principle of the semiconductor laser is a coherent radiation source, to make it generate the laser, you must have three basic conditions: gain conditions: to establish the carrier's reversal of the lasing medium distribution in the semiconductor represent the electron energy is close to a series of continuous level of the band to achieve population inversion in a semiconductor, between the two zone, at the end of the high-energy state of the conduction band the number of electrons in the lower state price with the top of the hole number.
Static applications, the main requirements of the tunable laser is the price, output power and spectral characteristics, that is quite fixed wavelength laser linewidth and stability and it replaced. Wavelength tuning range the greater the cost the better, not how fast the regulation speed. With more and more precision tunable laser for DWDM systems. In dynamic applications, wavelength tunable lasers can work regularly change, to enhance the flexibility of optical networks. Such applications are generally required to provide dynamic wavelength to one wavelength from a network segment or proposed to adapt to the changing capacity requirements. Other applications include reconfigurable optical changes in the multiplexer and optical cross connect in the wavelength converter. laser pointer can be used in different locations practically and efficiently.
As spare parts in order to save costs: tunable lasers can reduce the number of used to support the system in all the different wavelengths of the line cards required. One-time configuration: tunable lasers as both the main transmitter to do the backup transmitter, known as a one-time configuration, this is because its wavelength setting will not change. Most of the filters and other WDM is a specific wavelength. Therefore, it is not at liberty to change the wavelength. The customer wanna a specific pattern style of laser pointer .
Dynamic configuration: Systems Division was put into use, the wavelength of the tunable transmitter can be changed. For example: To meet the requirements of the wavelength of a new customer's network equipment and to change the wavelength of the transmitter.

The disassembly process of laser pointer is not complicated

The technical theory of laser pointer is very important to the production of laser pointer .
In line with the development of laser welding, plastics manufacturers are actively able to cope with the laser welding of materials. DuPont noted that the polymer on the near-infrared laser transmittance of at least 20-50%, in order to obtain good welding effect, while the vast majority of the qualities of plastic and have a lot of colored translucent plastic light transmission rate to achieve this requirement. In other words, the vast majority of plastic can be laser welded. On the other hand, the plastic on the near-infrared laser absorption rate is also an important factor affecting the welding effect, and most thermoplastics adding an appropriate amount of carbon black, you can dramatically increase their rate of absorption of the laser. However, laser welding for some materials, there are still some limitations. One typical example is the PPS and LCP, such as plastic, because of the near-infrared laser transmission rate is very low, if the two materials are filled with black light, because both are black, the laser can not penetrate, so the laser welding can not be. The disassembly process of laser pointer is not complicated.
The multifunctional laser pointer is taking up more market share. On the contrary, if the two materials are all transparent or white, near-infrared laser can be transmitted through, resulting in near-infrared laser absorption is low, this case, nor can a laser welding. In addition, many mineral-filled compounds, are not suitable for welding with a laser. These limitations, resulting in a series of laser welding of plastic used on the great barriers. To improve the transmission rate of the polymer and the laser absorption rate, and many plastics manufacturers to study, now to solve many technical obstacles. For example, BASF has launched a black material through laser Ultramid A3WG6LT (for nylon 66) and Ultramid B4300g6LT (for PBT). This uses a new dye material, although the black, but to maintain a high near-infrared laser transmittance, and thus achieve two kinds of black products for laser welding. The powerful function of laser pointer is very popular in the market. Longitudinal mode laser mode and transverse mode of the points, commonly referred to as the mean transverse mode. Transverse resonant cavity light field on behalf of the lateral distribution of the (perpendicular to the light propagation direction), when an important laser parameters, has a great influence on the welding results.
The output of laser pointer will be increased by taking some new measures. Shanghai scientists have developed a fiber laser to fiber laser output power has increased to a new level, maximum output power up to 107W, have been far ahead of the national counterparts. In 2004, Nankai University also reported a peak power of 206kW continuously pumped Q-switched pulse.

Laser Pointer can be used for the commercial application

Laser Pointer can be used for the commercial application.
As the laser printer is a combination of multiple technologies, their own work environment is more severe, some parts of the operating voltage is high, some parts easy to aging, oxidation, resulting in component damage or burn out, more dust inside the printer is particularly common. These can cause the printer software failure, components can also cause bad work good times and bad, so the vibration method in the repair process simple and easy after all, a good way. Alternative method that is similar to the new components or other components instead of a printer component. Sometimes the repair process, the failure of the components are hard to accurately determine whether the damage, there is no dedicated hand instrumentation. 
Turning on the power, to pay attention to the laser printer operating voltage, whether the external power supply requirements. Foreign purchase of operating voltage for the laser printer is a lot of 110V, do not take the wrong. After the cover is open when power check, laser printers into the self-test status. Pay special attention at this time, there may be leakage of the laser, can not be free to contact with high voltage parts, but can not use the multimeter to measure, in order to avoid electric shock and burn instruments. Laser printer is plugged in, the high temperature heating device (160 ~ 220 ° C), can not touch by hand to avoid burns. The temperature inside will have control pills only to discover. The ordering information of Laser Pointer contains many notes of Laser Pointer .
In this case, power should be reduced inspection time, avoid heated fuser roller and pressure roller melt overheating and damage. Note that laser printers are generally warm-up time of 1.5 minutes, so if more than 2 minutes warm-up is necessary to consider turning off the power, so as not to burn hot rollers and other accessories. Not available or other large-capacity fuse wire, replace the provisions of the capacity of the fuse and overload protection devices. When replacing the fuse first troubleshooting, and back to the new fuse to prevent failure further. Measurement integrated circuit chip, the chip should be used to measure the marginal method of circuit connection contacts. When measured against the foot leads chips, table pen touch short (due to IC leads to the foot of the arrangement is very close). The customer can get a lot of information of Laser Pointer from the ordering notes of Laser Pointer .
