I see the tape sticking to posts syndrome in my limited experience with HP QIC tapes also (DC100 / DC2000). The best I have come up with is wipe the posts with isopropanol. But I had not thought of lubricating them for a 1 time read, interesting idea. Or replacing the posts with ones machined from Teflon or Delrin?

In addition to the normal QIC band problem, I am seeing problems with the tape sticking on the metal posts that the tape goes around to change direction towards the reels. Should I try wiping the posts with acetone or wiping the tape with cyclomethicone? Should I be baking the tapes? If so, what is a safe way to bake QIC cartridges?
