The material procurement of green laser pointer

The material procurement of green laser pointer actually plays a very important and remarkable role.
Specifically, in the feed are used in cars to hit the spring on the left side of the rack, to promote the drive gear, press the paper lever, left, contact with the paper feed motor gear set, so the paper feed motor driven press the paper lever into place. The word car right then, the springs stretch drive gear disengagement with the paper feed motor gear set, press the paper lever to stop the movement. The printer gear has been damaged, the drive gear does not bring the press the paper lever movement, friction and noise, and detector press the paper lever can not be put in place, so that the printer crashes. Replace the gear after the fault has disappeared. Feed tune pole position detector. The detector is a mechanical switch, used to monitor the user's choice to feed the way. The customer can find and show the star to others by using green laser pointer .
When users use friction feed paper adjust lever to make the switch closed, issued by the OV signal to the CPU. On the contrary, if the user uses a chain fed, then the switch is turned on, the +5 V signal to the CPU. Once the switch is deformed, it will also report the wrong signal. The laser printer filling the powder guide. Add QMS color laser printer toner Note: First detection cartridge is suitable for adding powder, turn the toner side of the gear, the degree of visual magnetic roller on the powder is uniform, and whether there are scratches, uneven powder on the magnetic roller or The scratches are not suitable for plus powder. Scraper and the magnetic roller in the recycling industry demand is not large, but I think soon there will be replacement of spare parts are produced. It makes green laser pointer concentrate the energy very quickly and effectively within a short time.
If the above problem is not the case, the second step is to clean up excess toner inside the toner including the toner on the magnetic roller, which is very important. The bottom of the magnetic roller screw open, in order to remove the three sheet, then the magnetic roller to remove, clean up with a vacuum cleaner or Paper Tiger magnetic roller in the bottom of the sponge roller, and the remaining powder in the bunker. Above the first one to add a pink step, again the same brand, you can omit step 2. The third step is the toner into the bunker cover is open, shake toner and loading bunker, covered bunker cover, flat shake bunker, turn on the detection of the magnetic roller flour how, and then installed test.

Of great significance to improve product quality, reduce energy consumption. The principle of laser particle size analyzer. The laser particle size analyzer according to the particles make laser scattering test of the physical phenomenon of particle size distribution. Laser with monochromatic and highly directional, so will not hindered infinite space laser radiation to infinity, and in the communication process, there is little divergence phenomenon. Shown in Figure 1. Schematic diagram of the laser beam spread in the state without hindrance. Mie scattering theory suggests. This method of green laser pointer is very easy and convenient for the one.
When the beam encounters particles blocking part of the light scattering phenomenon occurs, the direction of propagation of the scattered light with the main direction of propagation of the beam to form an angle θ, and θ the angle of size and particle size, the larger particles, the scattering the smaller the angle θ of light; the smaller the particle, the greater the angle θ of the scattered light. Small angle (θ) the scattering light is caused by the large particles; scattering angle (θ1) light caused by small particles, as shown in Figure 2. Further study showed that the intensity of scattered light represents the number of particles of the particle size.
