Vutek QS2000 new heads, voltages right. printing striped/banded

[David Kulakowski]

put 3 new heads in for Mag. if voltage is set where the head says it should- i get overspray. had it set about 1.5 volts under and printed 15 sets of 4x8 no issue... now printing these- this is 3up on a 4x8...seems like Mag is dropping out by end...pics are in reverse order of how they printed.


I went through and did the bidirectional and step cals.... jet test looked good... kinda tearing my hair out over here....

Any Suggestions?

Thanks in advance!!

how does the check jets look immediately after starting to see the artifact? need to identify the suspect print head and hone in on the symptoms of dropout.
i would look at the bottom of the print head once you start seeing this, look for ink pooling / mensicus crashing / face wetting.
