Then we look at the charging fault, we first need to look at the parameters, that is, whether the viscosity is right, whether OK is displayed:

If the viscosity is OK, but charging is still not possible, we look at the split, we look at it with a magnifying glass here:

To adjust the ink point, we’re going to adjust the modulation voltage:

If the viscosity is ok, and then the ink point split is good, then we have to consider whether there is a problem with this charging pole, if the printing effect is not good, we should consider replacing this charging slot:





And then we take it down like this:



After we replace the new one, then the screws should not be tightened too tightly:
