So if you have a GX-77 with the roller stuck in the down position, it makes getting the controls off very difficult. It's easy enough to get the pinch rollers unbolted and removed with everything loose, but that little loading roller gets in the way. Well, the loading roller is attached to the plastic paddle that works the tape counter. It's just a friction fit, so you can pull the roller right off, and the plastic paddle will fall off inside the machine. Now you can disassemble the rest of the way, so you can get the rails off.
