green laser pointer to control computers at a certain distance

People can use the third generation  green laser pointer  to control computers at a certain distance. 
 Two serial parallel port connection. Carving and file output is not finished is interrupted. Operating the keyboard 4. Parallel port is sending data. Lettering software has been damaged, or computer virus infection. (6) equipped with inappropriate power supply. Will produce a strong interference in the relay off instantly. Caused by communication number It is wrong. 7. Of RAM or RAM jumper is not inserted, or RAM failure. This can have the following diagnosis: Hold down the "shift" Key and click the "reset", the yellow light will first flash.  Another technical innovation of the third generation  green laser pointer is the interaction of it and computers.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 function of laser was adopted in portable  green laser pointer .  Pressure of wheel wear variant, or the pressure roller can not match. Will result in about wandering around pressure roller should be slightly tapered, Head outwards. The pinch roller pressure is too small, paper is susceptible to external forces generated deflection. 4 sticky notes before and after weight ranges (eg, short in front and the carved figure is more complex, it will result in getting back Deviation, the best previous termination section of paper). Motor lost step caused the deviation. Sixth, both sides carved through the middle engraved, how do (2) knife block loose.
 Middle and low beams (4) pressure bar uneven Seven, I designed in Coreldraw graphics, how to output laser pointer   If you are using a laser pointer, install the driver (shipped with a floppy disk), the direct use of print Output, other machines can export the file as *. portable  green laser pointer  were not used for its laser function regardless of whether it can be used as pens, or as pointers. PLT format in Coreldraw, Wentai Read into the File menu, select transferred Wentai a slight adjustment to the output. Eight, the machine in the output file and found that the output error, I choose to turn off the power, you can?   Do not turn off the power, this will reduce the life of the machine. At this time, please press the pause button to cancel the PC Output tasks.
 The machine menu to clear the memory, large documents required to clear a few times.   First, press the paper round appear with fixed paper: too much pressure (using two pressure wheels). Deviation of the paper: paper not being on the uneven pressure, pressure roller, use three paper pressure rack, one on the left, right Two close together depressed. Platen handle broken: replaced with new handle. pressure paper frame can not move on the rail: to put lubricant pressure paper frame and rail contact parts.
