   Hi Pat,

          You didn't say what kind of material you're running through the sander. If you're getting glazed streaks on the sandpaper it's time to throw it out. This has happened to me when I've forgotten to scrape the glueline on a panel and run it through. Slightly green or resinous wood, like knotty pine, could cause the problem as well. The marks I would get are burns caused by the glue/resin buildup.

          Again, the only thing I have found to get rid of this problem is to put on fresh paper.

   I make it a practice to never pass any glued up pieces through the drum sander unless they have gone through the planer first. Any little glue residue will foul up the sandpaper. Also I do not put pine or woods with a lot of pitch through the sander. Sometimes a piece of wood with a large knot will foul up the sandpaper.
