What could be causing static cling to not feed out or roll up correctly on our HP800W. Sometimes it stops advancing while printing cause it gets stuck, and other times it will print, but after it advances it out to cure, it can't roll it back in cause it gets stuck. We have been printing on Static cling for over a year. Today we advanced a bunch of media out and then tried to get it back in and it made the noise like it was trying to rewind it back in, but it wouldn't move. Any ideas on what to test. Other medias works fine.
