Hello Again

This machine will print a few pages then it makes a "clunk" noise. From then on the pages output are not fusing properly.
  1. If I open the machine up the fuser pressure roller has "released"......which is why the pages are not fusing.
  2. I have checked the fuser itself. It seems all O.K. and the "pressure coupling" itself is not damaged or worn.
  3. I also disconnected the fuser pressure detect sensor to check what would happen. As the machine starts to warm up it displays an error, so the sensor is working.

Any Ideas on where to go to next ??
