We are running a HP Z6200, and I"m getting this weird "overspray" on our prints. The prints are just solid color with White type. We are getting these lines going in the direction of the carriage motion. We've turned the file, and the lines stay in the carriage direction. I've updated the firmware. re-calibrated, change print heads, I can't seem to get rid of it. It's also doing it to the same file re-ripped and printed on Photo Paper. Any ideas?
