The first generation of portable green laser pointer were used for single purpose

portable  green laser pointer  couldn’t be used to stretch into pointers at the very beginning.
Check the water circulation system flow is smooth (water pipe bend or burst water main); 2, check whether the normal focal length (recalibration); 3, check whether the optical path (re-calibration); 4 Check the plate capped with paper is too thick, the water is too much to (re-corrected); 5, check the beams are parallel to (adjust both sides of the belt); 6 Check that the lens is broken (replacement); 7, check the lenses or laser tube transmitter is contaminated (re-cleaning); 8, check the water temperature is above 30 ° C (to replace the recycled water);  On the basis of an extension of other electronic functions, the second-generation portable  green laser pointer  are developed.The third generation  green laser pointer  are made up of a locator and laser.  The sticky surface wrinkling bubble too much. Move back and forth so that the compression part of the paper has been too much resistance and deformation And backward rotation of the main roller, resulting in shape distortion and sealing. Software settings inappropriate. 3 car belt is too tight; or main roller screw loose; loose or the motor shaft gear, make the car or the main roller Can accurately follow the motor movement caused by the shape distortion and do not seal. 4 shape without distortion but do not seal, software closure compensation value is too small .
  The first generation of portable  green laser pointer  were used for single purpose.  (1 M RAM flash 2 times, 4M of RAM flash 8), slow green Flash (1 M of RAM flash 2 times, 4M of RAM flash 8) Finally, the yellow light flashes twice, indicating that the RAM correct. If Failure. Yellow or green light in rapid succession flashing, please contact your dealer. , Why would the deviation phenomenon? . Sticky start did not put is: 60CM paper put skew 06MM paper 5 m wandering around will be 5 Meters. Table dirty or sticky adhesive residue, so that the paper movement on both sides by the imbalance of Yin force, leading to production gradually Health deflection. Caused by the left and right deviation.
 The knife itself internal bearing swivel inadequate. The font in the font is not the same carve the result is not the same. V., carve part some strokes or word mortgage down: pressure damage or graver rotation is not good.  The one-end portable  green laser pointer  had no difference from children's toys. The left and right ends of different shades: rail uneven one end and low end of the. The the definition of 3 meters to carve two meters: Wentai software output length is set to limit the compensation set. knife pressure in the lettering process different shades: static interference, the use of shaft grounding method.
