Fixing machines is sometimes like a point and click adventure. The sensible and straightforward approach to the problem isn't immediately available so it's either MacGyver something that works well enough until a proper fix is possible or shut down and lose a ton of sales. I'm surprised at how well the temporary fix held up, but the machine is much nicer to use with a proper repair. While the temporary fix was in I also forbade anybody else using the machine, but now I can lift that restriction.
