I've been banging my head against this slot for about a week now. Really appreciate the help thus far. My previous issue(Coin-In Jam Error) is gone thanks to the door I/O cards from RB. Once the current problem is solved I will mark the Coin-In Jam error thread solved.
The error I am now seeing is the 7-Segment Display Mismatch. This was not present prior to switching out the I/O card in the door but now, other than call attendant and Closure M, are the only errors I am getting.
Through googling I have noticed that most of the issues with this error has to do with the battery. My watch battery is good, 2.92 volts and the Varta is also good. The other issues apparently are from converting the machine to another theme which isnt the case here.
Anyone have a suggestion on clearing this? I have tried clearing the errors by using the door lever.
