The green laser pointer is the brightest laser pointer

The green laser pointer is the brightest laser pointer.
And then measuring the sensor transmitter (BH8-1271-02) CE voltage for 0.9V normal attention to measurement should be carried out in low light, because this group of sensors, photodiodes, if the light is too strong will cause measurement is not accurate. Open the rear cover of the machine in the drive plate (BH8-1275-06) found on potentiometer VRl4, counterclockwise to minimum, and with a multimeter to monitor the AK voltage across the voltage of 4.2V (exception), normal 2V or so. Two consecutive compressions Access witch key machine display still shows error code 10. Shut down, find another set of sensors P512, this sensor group is exactly the same P513, swap the two connectors to each other to power the machine self-test. The star gazing is another application of laser pointer .
The screen displays an error code 11: FILM JAM, ? the PRINT, the same way the two sets of sensors restored, reboot the machine error code 10. To this description of the sensor group P513: damage, ordered a new set of sensors put to the factory, the machine still is not working, because the newly purchased sensor group parameters and the parameters of the old sensor group do not need to debug. Since manufacturers refuse to provide debugging information on vehicle maintenance, amateur can use the following method for debugging. First of all, the driver board (BH8-1271-02) to find the VR14 potentiometer counterclockwise to minimum continuous quadratic the Access switch key. The need is on the basis of the technology and design of laser pointer .
Clockwise to adjust VR14 until display shows error code 10, then the VR14 counterclockwise to adjust a little bit back, the commissioning process should be carried out in the dark environment in order to avoid errors, debugging after a laser sheet inserted in the the middle of the P513 sensor, if the machine display error code 10, then the successful commissioning. Shutdown, re-install the machine to reboot after 10min machines show everything is normal. Enter the program menu, select Print a test piece, the machine began to work while the error code. Check the manual explains The jmn occurred in the Receive Magazine win-dow area. The customer can show the star clearly with laser pointer .If laser pointer  is necessary or required by the customer
Meaning for the card in the closing of the window area of the cassette, turn the machine on the left side of the board, a laser-chip card in the closing piece box and carefully removed the laser sheet and re-installed machines about Access switch button and the machine still display the error code 13, and re-click Access witch were harvested for the cassette and to close the cassette, and then shut down, reboot 10min machine prompts insertimagine, re-fitted to close the cassette for cassette, press the Access switch , the machine displays the normal state, print a test piece, everything is normal.
