Okay so we just got this printer maybe about a month ago and it was going really well until the last 3 weeks. We have been having trouble with the rollers making marks in the media. We only put the rollers down one click like you are supposed and we have tried: Turning the heat down, putting the rollers fully down, different medias (even the ones supplied by GRS), The media is tight and centered...I'm all out of ideas here has anyone else had this problem???
