Bally 6000 Coin-out Optic Error 31

[Bren]

Hi, a year or 2 ago my family purchased a bally 6000 roaring 20s 3 reel slot machine. At the time it worked an we played it but at one point it stopped working and we never bothered to fix it. I recently decided I wanted to get it working again although I had no idea even of the model or how to go about. I started googling and reading and managed to replace the battery and Saferam clear it. I fixed a few other issues but now it gives me error 31 which is the coin-out optic. I have tried cleaning it, checking connections, and looking through the 11d menu and correcting things but nothing seems to work. I'm seeking advice and help please.

The optic the the hopper is dirty with dust or failed. There is a sender and receiver on the optic sensor.  Blow the dust out of both. Be sure to open and close door 2-3 times clear the errors. If that doesn't clear the error you will need a optic for the hopper.

I've attempted to clean out the optic a few times and nothing seems to work, where could I get a new optic for it?
