  • Hello, this problem happen me usually in all printings...
    Always is the same:

    Like i said before, this not only happen me 1 time. Happen me 4-5 times, what is your opinion?

    Best regards



  • does your psu have a poweroff feature that you are using?

    if not your power supply might be failing



  • Not use PSU, always is on...

    Check that the screw down terminals for VIN are tight. Make sure you are using the crimped bootlace ferrules.



  • After test a lot time i can say that with "crimped bootlace ferrules" everything is ok.

    Thanks a lot!
