If our Videojet 43S machine starts up normally, the high voltage fault is reported, which is an overpressure trip.
This fault is called an ultra-high voltage trip, also known as a high voltage fault：
Then let’s take a look at our side and see if there is ink on the high-pressure deflection plate on this board ：
If there is any dry ink, we will clean it thoroughly ：
Then make sure to blow dry this piece, and after cleaning, blow dry all of it ：
If we blow dry and then turn on the ink thread.
After turning on the ink line, it still reports this alarm or this fault
So we need to use a magnifying glass to see if our ink dots are splitting, okay:
If the ink dot splitting is not good, then we may have a slight blockage in the nozzle. We need to clean the nozzle ：
Or perhaps our ink has deteriorated, which requires us to maintain the machine and replace it with a new one. This is the second situation.
The third one is: if everything is replaced, it will still alarm or report a high voltage fault. Even the machine has been maintained, and our area is also dry. If it continues to report this high-voltage fault, then we may also have a problem with the high-voltage package and need to replace it:
