I wish I could help you about your make of ATM. We have a Triton 1600AC here. It has yet to fail us but on certain days when we have the highest solar activity, nearly anything can "freeze up," making anything electronic beg for mercy.
If you have a pacific Rim ATM and are thinking about a new machine that doesn't make your customers use nasty language and walk out thirsty then give these good folks a shout.
