We recently updated a Standard 500
changer to use the MEI Mars bill acceptor. Process was fairly easy and the Mars made the system more reliable.
However we now have an issue with the hopper motor axle. The motor turns but does not turn the hopper wheel. Spoke with Standard tech support who pointed out the roll pin that holds the axle to the hopper wheel, we installed a new roll pin but motor axle still does not turn the hopper wheel. By the way tech support said the pin is likely to break if you put too many quarters in the hopper. Never had such an issue with
Hamilton
Any other ideas of things to look at?
