This may not work, and it sounds dodgy, but if this is the same problem it
_may_ work.
The Jumbo apparently detects the end of the tape opticaly; at the end of the
tape there is a transparent section, and a photocell arrangement is used to
detect this. What can happen is a dust build up on this photocell. The way
to rectify this (this sounds terrible) is to blow into the tape unit as
hard as possible! I've seen this work and the tape unit worked fine; I'd
reccomend a can of clean air instead of just blowing though.

Good luck!
