What have you found that works to control arcing. I seem to run into this in the winter(I'm located in Wisconsin) on cover stocks mostly. I know overall printer temp setting is a key factor.(mine was bumped up by my service tech and field expert) Once the printer is "warmed up", it's not too bad. I also know the environment the printer is in has a lot to do with it too. Humidity control is very important. Anything else you could add to this discussion would be great.
