And I'd not thought of it 'coming off' in any sense other than running
off the spool....

What would happen if the tape head was tilted (front-back) relative to the
guides in the cartrdige? Could that put a sideways force on the tape?
Maybe the cartridge isn't seating properly,or the head guides (does it
move the head up and down to change tracks?) are misaligned or something.

I don;t see how that could be the problem.
