I had a coin jam in my Rowe C-10RL that I was testing (error message “Er 8”).
Pictures of the coin hopper motors and coin chute.
I still got the “Er 8” error after clearing the coin jam so the instructions say it could be paper or something blocking the led or sensor. The left side looked fine so I attached everthing and reset the changer and got “Er 9” which means the same thing only the right side. Everything looks clean and fine but I guess I will be replacing a sensor because the led works fine.
