Apart in disk drive after careful observation, found no small machine core when in storage disc cartridge reset process is normal, insert disc storage box 1 began to load, rotating disc bit conversion motor immediately stop, and motor driven piece of rapid heating hot, when the power is cut off manually remove the disc storage box, manual emulation read 1 disc process, and no mechanical jam phenomenon, failure analysis and related to the load disc storage box. After pushing storage disc into the manual simulation read 1 disc process, find the appended drawings shown in motor shaft worm in turning laps increase resistance to unable to rotate, after analysis this should be an electric box storage disc bit conversion motor turn the stop, and show the cause of the fault code of the E3. Is after careful inspection, found that small machine heart disc tray retractor and disc storage box on the left side of the tray and hook touching, make small machine core difficult to return to no. 1 disc position caused by the fault. The small machine heart worm gear off and adjust the lower right side of the gear and rack, try to move to the right in the end, and then recover. Manual simulation 1 disc read again, no jam phenomenon. Commissioning, small machine heart move up and down after the disc bit conversion motor driver once, at the same time, small machine heart worm wheel rotation to reset the tray retractor, loading disk storage box reading disc normal, troubleshooting. yZyservice manual download site

Note: if discover mechanical maintenance jam phenomenon should immediately without electricity, or for driven integration block heat up very easy to burn out quickly, in principle, should be ruled out jam phenomenon after the electricity. yZyservice manual download site
In addition because mechanical parts frequently movement when the machine work, easy to cause dry grinding, running resistance increases, can be appropriate to add some video general lubricating grease, practice has proved that the special grease excellent performance, flexible, convenient to ensure machine running prolong service life and reduce the failure rate.
