Quoted from EvanDickson:
Can someone tell me how this works on their Taxi?
When I launch the ball, it goes through the spinout, then kicks out across the back of the playfield and into the Joyride saucer. A few times in the last few games, it has kicked out of the spinout and then hit a gate in front of the saucer, forcing the ball to drop through one of the ABC lanes. I can't tell if a switch needs fixing to make sure that gate is open, or if something that hasn't worked right before is starting to work, and the ball is supposed to be kept in the A-B-C lanes on launch.
There is a swinging wire to the right of the CAB lanes that allows the gate blocking the Gorbie shot to open momentarily. Otherwise it should always be closed preventing what you are describing.
Check that gate/wire?
