Open the machine cover, to set aside the laser components, electricity, laser components inward sliding smoothly. Since laser components can slide back and forth, and can actually read the track, time, and can display images of the 2 minutes, illustrate the RF pre/servo signal processing, digital signal processing (DSP) and servo driver circuit is working properly, failure can only appear in places associated with laser components movement. Associated with besides feeding motor, transmission gear, slider, is laser components and single flat ribbon cable and socket 16 feet. Bottom line measurement, the corresponding side is same, check the corresponding socket without poor contact. In a good laser components after commissioning, fault, sometimes couldn't read the stuff, shows 00 m00. After repeated analysis still think fault may be poor contact or rows of fracture. Hence to pull out the bottom line, the measure after pressing, finally measure three root of bolt, determine the cause of the problem is in this line. ysNservice manual download site

Analysis the cause of the problem is the ribbon cable is relatively short, in use process, row line reciprocating movement easy appear fatigue bending, broken to a certain degree of copper foil. When switched on, laser components, I always slip into the state of reset, the ribbon cable bending upwards, has the certain tension, to break through, everything is all right; Move outward and play laser components, to two minutes, ribbon cable tension is abate, broken broken, the failure occurs. ysNservice manual download site
Maintenance practices show that the single line, which is connected with the laser broken caused by the fault phenomenon is differ, but the main problem of the machine, maintenance please try it in a new row line, often can instant solutions, spend less time and energy, little detours.ysNservice manual download site
