Snax4U Posted June 27 Share Posted June 27 Greetings gurus! I have a DN3000 that is no longer my favorite but we're in this together. Sooooo, when a customer makes a cashless purchase, doesn't matter if tapped, inserted or swiped, the product is provided and change is given. Example...Customer taps card to Nayax reader and receives $4.50 preauthorized credit as my energy drinks are $4.50. Customer selects Gatorade ($2.50) machine provides the Gatorade and $2 in coins. This is happening with various cards including the Nayax prepaid card. I have since disconnected the reader and battled with Nayax and ended up with a replacement reader. (all is the same minus providing change when using card) On top of that, after dispensing change, the machine cycles as though just powered on. The gate triggers cycle, the bill acceptor cycles and the led on the machine resets as though the door was just closed. After disconnecting the reader, the issues went away but it's a high traffic area that REALLY uses the card reader. Oh yeah, these issues arose after an update, Nayax pushed. Suggestions/advice? I'm not open to dumping it and am able to spend to repair but not sure the best direction to take the next step in. Thanks in advance. Link to comment Share on other sites More sharing options...
AZVendor Posted June 27 Share Posted June 27 Kind of sounds like you need to update the eprom on the machine logic board for starters. Link to comment Share on other sites More sharing options...
Vendo Mike Posted June 27 Share Posted June 27 Sounds like you need a firmware update on the machine. Link to comment Share on other sites More sharing options...
Snax4U Posted June 27 Author Share Posted June 27 Thank you both for quick responses. AZ, I was looking on dsvending and it altars the 3 eproms, Pepsi and Coke specifically match what's in my machine. 👍🏾 Vendo, firmware update can be accomplished how? Updating the eprom?

Vendo Mike Posted June 27 Share Posted June 27 Yes, updates are via Eprom. Generally you'll save Coke or Pepsi for their branded equipment. Those bottlers usually have some specifics in their programming to make it their own. Even if it's something as small as the sales message reading "Enjoy a ####". If you're using an unbranded unit, you'll probably want the 3rd option. Link to comment Share on other sites More sharing options...

Snax4U Posted July 4 Author Share Posted July 4 Greetings folks From one thing to the next but I am open to the feedback. After swapping the eprom, now I am dealing with "not connecting to machine board,' error. No clue what step to take next today. The intention is to attempt a call to Dixie Narco or locate someone knowledgeable about the Dixie Narco 3000 model. Any suggestions? Link to comment Share on other sites More sharing options...
Vendo Mike Posted July 5 Share Posted July 5 After replacing the EPROM, did the rest of the machine reinitialize correctly? If not, you may have installed the new eprom incorrectly. Link to comment Share on other sites More sharing options...
Snax4U Posted July 6 Author Share Posted July 6 Hello Mike It did however, the DNC ERROR, no communication with MB popped up. Useless at this time because the default message is NO SALE as there no comment with the board. Link to comment Share on other sites More sharing options...
AZVendor Posted July 6 Share Posted July 6 I would say the board is bad. It's also an ancient board so do you really want to keep putting money into this machine? Link to comment Share on other sites More sharing options...
Snax4U Posted July 8 Author Share Posted July 8 Considering the price of a new board...nope Why wouldn't it operate when the original eprom was reinserted properly? At least I'd be able to "get by", now it just looks good sitting there practically useless. Link to comment Share on other sites More sharing options...
AZVendor Posted July 8 Share Posted July 8 You can get rebuilt logic boards so that is worth a try. It's all that will work in that machine anyway since DN long ago stopped providing SIID upgrade kits for the SII machines. 1 Link to comment Share on other sites More sharing options...
AZVendor Posted July 9 Share Posted July 9 I apologize but I've been replying to this thread as if it was the thread about an old Coke machine with an SII board. Sorry for that confusion. Link to comment Share on other sites More sharing options...
Vendo Mike Posted July 10 Share Posted July 10 Curious if you've lost a fuse or left something unplugged for it to no longer recognize the driver bd. Link to comment Share on other sites More sharing options...
Snax4U Posted July 13 Author Share Posted July 13 Thanks for entertaining this guys. I've attached photos to see if it will help in troubleshooting. Open door startup... Link to comment Share on other sites More sharing options...
AZVendor Posted July 13 Share Posted July 13 That is just the notice that there are errors stored that you need to access. Will it not let you access the Error menu? Link to comment Share on other sites More sharing options...
Snax4U Posted July 13 Author Share Posted July 13 Yeah. Wouldn't let me upload due to file size. After accessing error...I saw DNC ERROR then, Link to comment Share on other sites More sharing options...
AZVendor Posted July 13 Share Posted July 13 So you are having the Machine Board No Communication. The thing is it doesn't tell you what isn't communicating so we have to assume it's the coinage. I would first disconnect the card reader and bill acceptor and only run the coin mech to see if the message returns. Make sure you delete the error message first. Then if it does return you know to try a different coin mech. If the error doesn't return then plug in the bill acceptor and check for the error again and lastly reconnect the card reader. If none of them trigger the error to return then try test vending every shelf then you might need to focus on all selections on one shelf. It could even be a problem with the delivery port or the conveyor. If nothing works then you need a replacement logic board. 1 Link to comment Share on other sites More sharing options...

Snax4U Posted July 14 Author Share Posted July 14 No luck. Bad main board. 🤷🏾♂️ Link to comment Share on other sites More sharing options...
AZVendor Posted July 14 Share Posted July 14 I figured that would be the end result. Link to comment Share on other sites More sharing options...
