Boazcat Posted July 27, 2011 Share Posted July 27, 2011 I've got a snackshop 7600 with a MEI Series 2000 bill validator I can get it to accept the bill and make one transaction. However, the next time it will accept the bill, show a credit of $1 and then spit the bill back out when you make your selection. I've cleaned the validator and have a solid red light - no errors I have plenty of change The product costs $1 and I've checked it I've unplugged and then unplugged the validator. When I start up, it works once and then not a second time. It sill take coins, just not bills. Anything else I can do without switching it out? Is it a board issue? Thanks, Michael Link to comment Share on other sites More sharing options...
Vendors Tech Posted July 28, 2011 Share Posted July 28, 2011 The only other thing it could be besides the board, is the coin mech. Try that first. I would switch boards next. What happens with the LED light on the board during the first and second transaction, and does it do the same thing with the door open? Link to comment Share on other sites More sharing options...
Technivend Posted July 28, 2011 Share Posted July 28, 2011 It may actually be in the validator. It has something to do with the final communication after the selection is made. It's goes kinda like this. val-Hey someone is trying to insert a bill can I take it mach-Sure we got change val-Ok I'll take it val-I got it mach-ok we'll let them buy something mach-wait a minute something is wrong val-ok, I'll give them the bill back. Electronically it is a very primative way to do things but back in the day it worked. So try the val before the board. Link to comment Share on other sites More sharing options...
