Chapter X Basic Troubleshooting
Troubleshooting Cases
1. Print garbled ( motherboard or motherboard data line problem)
2. drive error ( machine main power, screw bar, drive motor signal problem)
3. Raster feedback signal error ( raster decoder, printhead data line,
motherboard, )
4. Limit switch error ( limit sensor failure or no sense )
5. Printheads overheat error ( lower operating ambient temperature )
6. Drops of ink or ink off ( ink sac leaks or secondary cartridges without ink )
7. Lifting motor sound abnormal or unable to lift ( if the lifting screw is vertical ,
excessive resistance will lead to lifting overload or damaged )
8. Setup the highest point of Z axis ( if the highest point of Z axis is not set up,
the machine will not move )
9. UV lamp automatically turns off when printing ( currently encountered
mostly because of poor heat dissipation, caused by cooling network
congestion )
10. Motherboard can not detect ( communication problems )
11. Printhead data loss ( printhead data line is not plugged in )
12. Printing not actual print range ( imit switch adjustment inconsistent or
before sensor position)
13. Driver can not updated ( motherboard or computer problem)
