When we went to use it I noticed that the fan on the laser was off. I turned it back on but the cuts weren't as clean as they have been. I believe that it may have allowed for residue buildup on the lens. I didn't want to mess with it unless I was certain I knew what I was doing.<div>Joe</div></div>
