Over-spray/Static problems

[wickedwatcher]

Hello, "First time poster, long time reader"

I have a Roland XR 640 machine, and one of the main problems I am having at the moment is over-spray. I have super clean heads, have done feed direction calibration, along with the Bidirectional alignment (both simple and detailed) and everything is perfect.
But on all medias, I am still getting some very heavy over-spray, which I am wondering if this is due to static? If yes, does anyone have any suggestions to resolve, if no, does anyone have any other theories and solutions?

Check that your head height is “LOW”. Then try paper. If the problem remains it’s not static (for the most part). You may have either bad ink or a bad print head.

Which channel it’s displaying the most overspray?
