However there are things that can go wrong inside an Accu-Vote that can cause it to corrupt memory cards and/or crash (ISR, lockup*, random jump to a different prompt, etc). Thus I recommend a procedure of recording such events and if any single machine experiences 2 or more occurances over the course of an election, it's grounds for requiring service. Don't worry about a single occurance on a machine unless there is other evidence to suggest problems with that machine.
* Note that there are 2 different types of lockup. The most common seems to be that the older scanner units would lockup during operation but the AV itself is working fine. Recent firmware (since 1.94p/1.94f<) will display an error message if you hold the NO button for more than 3 seconds while the AV is waiting for another ballot in a count mode. If this works, the AV is working and it's the scanner unit itself that has locked up. I don't believe that scanner lockups can affect the memory card. Ian, when do scanner lockups indicate a need for service?
