The laser printer works somewhat similar to the copier

When the customer is not using  green laser pointer  but they don’t have the right place to keep it
The laser printer works somewhat similar to the copier, but there were significant differences in some aspects. The most obvious difference is the source of the image: copier image emitted light to scan the images, two laser printers, while the digital format to receive image data. The second stage: the laser scanning system. Focusing mirror, the laser scanning system mainly consists of lasers, mirrors, multi-faceted rotating mirror, wide-angle synchronizer sound and light deflection modulator and other components. Lasers. The laser is the light of the laser scanning system, directional and monochromatic, coherent high energy concentration, ease of modulation and deflection have to point. Or we can say the cost performance of  laser pointer  means price being divided by the performance.
Commonly used laser helium - neon gas lasers and semiconductor lasers. Acousto-optic deflection modulators: the working principle of the laser modulator is the effect of the acousto-optic diffraction grating, when the laser beam to the ultrasonic medium (such as crystal, glass), the laser beam is generated diffraction, the intensity and direction of the diffracted light with ultrasonic frequency and intensity changes, the so-called acousto-optic effect. Laser scanner. Modulated laser beam to complete the horizontal and vertical scanning in order to produce the complete text and images on the photosensitive drum, longitudinal motion of rotation of the photosensitive drum, while the horizontal movement of the scanner by scanner . Of course, the customer should consider whether the parameter and performance of  green laser pointer  conforms with the real needs and actual requirements except for the cost performance.
Optical system. The role of the optical system is generated by the scanner the size of the scanning beam integration provisions, and the drum models of uniform linear motion, the optical system according to the different position of the lens in the scanner before and after, is divided into two before the lens type and lens forms. But after the objective lens type distortion in the scanning of large graphics serious, so the majority of laser printers using the lens before the light path system, by a combination of multiple lenses together to form a wide-angle focusing mirror optical system. Phase III: Electronic phase imaging system. The laser printer is a precision mechanical system that uses optical, electrical, thermal, physical, chemical principles through interaction of the output text or image, the complex process by an electronic control system to achieve, referred to as electronic imaging system. It cannot be called a good or appropriate choice of  green laser pointer  for the customer.
Electrostatic imaging theory is first proposed by Americans Carlson, also known as the Carlson method, or the so called discharge imaging. The basic process can be divided into: charging, exposure, developing, transfer, fixing, clean, eliminate power seven steps, five steps around the electronic imaging system carried out. Electronic phenomenon system reagent (magnetic reagent and non-magnetic reagent), we can put roughly the electronic imaging system is divided into two kinds of magnetic imaging and magnetic imaging system. Charge both for charging the photosensitive drum, to impose a uniform layer of negative charge on the surface of the drum, making the surface of the drum to produce a uniform layer of negative electric potential layer and to maintain this constant potential. Different kinds of  green laser pointer  of different parameters and performances can be used in different locations and for different purposes.
The drum surface of the photoconductor material in the case see the light as an insulator, neutral state, with any charge. To achieve the photoconductor surface, electrostatic latent image, we must first charge the photoconductor surface. Laser printer drum charge, due to the different models using the specific charging method are also different. Scanning exposure is like a pen to paper and write the scanning exposure tool is a laser beam "writing" on the drum exposure, the picture or text is not visible, and this is what we call "electrostatic latent like ". Drum charge, when the bright part of the laser beam shines on the surface of an area, known as exposure. It is the waterproofing green ray   green laser pointer   with LED indicators and compasses.
