Take top off of computer. Look straight down in middle of computer. There is possibly a rubber gear and a repositioned metal gear driving the money wheels. There was a company that made a rubber gear and a jig to drill a new hole to realign the metal gear. Kit also contain a magnetic strip with plastic numbers for pricing. Just fill in price and place strip on computer face plate. I installed lots of these kits in Illinois for Clark Oil. You can just pop off gear and move gear over for pricing to be normal. Dan.
