This is a quick video of the SEC E9 Key code machine, this is a small problem I have found with the machine, if you do a decode and it has a problem, it will pull the carriage back, then next time you try to use it will hit the back wall and stop. In this video I show you how to move the carriage forward so it can recalibrate. If you have this problem, move the carriage forward, then re-calibrate , then try again
