Error Code "C.O."

[angryninjas]

I have a Jackpot machine, and when I turned it on today an alarm went off and code "C.O." appeared in the coins played window. Worked perfectly fine last night. I did a reset, but it didn't appear to do anything, and still shows C.O. in the coin window with the alarm going off. I tried going through the changing odds procedure, and that didn't help either. To my understanding, a hard reset is the same as changing the odds, except you turn the key back to play mode while holding the spin lever down, correct? Any ideas what the cause could be, or what is needed to fix the error?

simple as a token stuck in the hopper or as hard as a bad sensor...

have you check to see of the hopper is still turning freely??

Yep, nothing wrong with the hopper. No idea where to even begin

Hello

I know you have tried the reset, but just wondering if you have completed all the steps fully in the correct order, as it is really easy to miss something out and your machine will then not reset:

Here is the procedure:

Most errors are usually remedied with a full reset, so just to double check that you are carrying out the complete hard reset

Here is some info that explains how to reset a pachislo, as part of this process it includes how to change and set the skill level, you must follow all steps carefully

"How To Set the Skill Levels of Your Pachislo
HOW CHANGE ODDS:

"TURN YOUR MACHINE OFF FIRST"

1. Locate internal key switch, and insert key.
Note: In order to change odds, machine must be in idle mode with no tokens/coins or credits being played and off.

2. Turn "reset" key switch to on, to access programming mode.

3. Turn on machine now.

4. Depending on machine type, a number from 1 to 6 will be displayed on one of the LED meters on front door. (please note on some models the numbers could be displayed inside the machine)

5. Locate and push Skill button. Depress button and notice movement of number being displayed in LED meter.

6. Once desired level is displayed (1 to 6), push down on play handle (Joy Stick) for 10 seconds, and depress both "BET CREDITS" and "COLLECT CREDITS" buttons to lock odds level into machine memory.

7. Turn "reset" key back to off.

8. Machine should immediately initialize. If not, turn power switch to the OFF position, wait 15 seconds and turn power switch back to ON position.



It might be worth trying that again, just to make sure
