Have 2 verifone 3750 credit card machines. both will not work. You perform transaction, they process and the paper moves a little and the green light starts blinking. The only way to get it to go to full green you must unplug power and replug.
You try transaction again, it starts to move paper and quits and the green light starts blinking again.
