Royal Ace CR error wont clear

[bdavis9179]

I have a royal ace machine that has a CR error that wont clear. I have done multiple reset attempts and removed and inspected/cleaned every connection point along with the coin hopper and the coin mechanism. I have replaced reset keyswitch and I am able to change the odds so i know im in setup mode but CR always comes back.

I've read on another thread that the "photo eye" on the coin mechanism was dirty or faulty. I have cleaned this one but how can I verify that it's good or bad?

Depending on the token acceptor. It may have 2 or more sensors.
Turn off the power. Unplug the token mech. Turn on and try a reset. If it starts without error. It's going to be a duff sensor. If it still goes to error. Ot not definite. If you can see the sensors whilst the machine is powered up. Try pointing a digital camera at the emitter side (not an apple device) you might see a bright glow on the screen. This again isn't definite. Of no glow from any part of the sensor at any angle. Then it's duff. If you see a glow. It just means the emitter is working but the receiver could be bad.

Some machines have led inputs on the cpu to indicate any/all inputs. You could try making/breaking the beams and see if you get an indicator. Then check the other sensors to confirm.

Or of course you can do the above with a volt meter and check voltage. But this means working out the sensor data sheet and seeing what pins do what.

When i unplugged the coin mechanism the error changes to CC. Then I plug it back in and it goes back to CR. I also unfortunately dont seem to have the LED lights to verify function of my buttons and sensors on this machine

Daito seemd to have changed their error codes. The only CR I can find says.

C r セレクターセンサー異常 センサー確認後、エラー解除（部品交換の必要あり）

C r Selector sensor abnormality After checking the sensor, the error will be cleared (parts need to be replaced)
