I actually had one of these again today. It wasn't that particular sensor this time, it was caused by another sensor becoming loose. The sensors as you know only clip into position on a metal bracket. The sensor number 27 (section 4, number 3) in the service manual had become half unclipped on one side, causing the sensor arm to miss the sensor. It was also causing the paper to stop just as it would be released. Basically the same symptom, now I know has 2 different causes.
Take the entire side cover off the finisher (the vertical cover beside the output tray) and all the sensors and plates that hold them are directly behind it.
