The above suggestions are very good, also hand feed the freezer paper in, one piece at a time.
I put a big X on a piece of copy paper, put it in the tray, X side up. Now print a pracitice sheet. If the printer prints on the X side, you know to put the freezer paper in paper side up. If it prints on the non X side, put your freezer paper in waxy side up :wink:
