Dekinha Posted June 26, 2015 Share Posted June 26, 2015 The tubes are filled but the message exact change problem appears. My coin mech is MEI 7612 brand new. I thought it could be some coin mech problems so put 2 other brand new coin mechs but the message appears with all of them. any insights?

AngryChris Posted June 26, 2015 Share Posted June 26, 2015 Try doing a tube fill using the machine's tube fill function. Link to comment Share on other sites More sharing options...
cvending Posted June 26, 2015 Share Posted June 26, 2015 I agree with Chris. Empty coin cassette then go to tube fill in menu(not sure what machine you have) and fill by depositing coins through top of coin mech. Link to comment Share on other sites More sharing options...
Dekinha Posted June 26, 2015 Author Share Posted June 26, 2015 I did both, filled the tubes using the machine (the message appears) then filled using the coin mech (the message appears too). I have an old Polyvend 6640. Prior to use this brand new coin mech I used an old coinco that had only 3 options of coins. It failled and I had to change it. and the new one has 5 tube coins options.

Technivend Posted June 26, 2015 Share Posted June 26, 2015 Try buying 5 dollars worth of product with change and see if that helps Sent from my Nexus 5 using Tapatalk Link to comment Share on other sites More sharing options...
AZVendor Posted June 26, 2015 Share Posted June 26, 2015 The CF7612 is for export to South America which I recall is where you are at. The Polyvend 6640 will probably not handle a coin mech that new properly. You should go back to a three tube coin mech that the machine was designed to work with.

The new coin mech give change for the higher product prices but the cheapest products the message appears. the problem is the change in small coins, I changed the configuration but the problem continues.

KychrisKy Posted June 27, 2015 Share Posted June 27, 2015 I've got a cb700 that says exact change from time to time but still works prefect, I think my board has issues but still functions properly, Link to comment Share on other sites More sharing options...
