Need Help Anyone know what causes these marks in adhesive vinyl when printing?

It looks like both a burn and a scuff but i've reprinted it a few times and it's moving around.

Thanks

Those are head strikes. Turn the heat down and the vacuum up. You may need to put the head in high head height mode.

Thanks, I've currently got temp to 40,40, 45. Is it where it is making the paper wave up and down a little and then that is clashing with the paper? Quite new to all this obviously

You got it. I normally have my settings around 33, 35, 50 but it is going to be a little different for most people depending on the environment and what type of media you are running. 50 on the post heater helps ink curing and shouldn't affect the media.

Thank you very much for your help.
