Noah Posted November 19, 2021 Share Posted November 19, 2021 Of the 73 machines I currently operate, I have 10 AP 123A/123C machines. Every so often they display an error code of "m 3.22" or "m 2.74." I usually just clear the error code and move on. I'm wondering if anyone has any knowledge on what that error code means or what actually causes it? Link to comment Share on other sites More sharing options...
lacanteen Posted November 20, 2021 Share Posted November 20, 2021 I've never seen or heard of these error codes. I was factory trained when these machines were built and now operate 87 of them. Perhaps your firmware is old. Should be 5.24 or higher. 1 Link to comment Share on other sites More sharing options...
