HopeVendor Posted March 12 Share Posted March 12 My MEI CF 7000 coin mech all of a sudden just stopped giving change back. I’m getting message on the display about the tubes being uncalibrated. When I press the button to calibrate, I get the message “hardware error” Cal. Failed Any thoughts on how to fix this? Link to comment Share on other sites More sharing options...
Vendo Mike Posted March 12 Share Posted March 12 If it's not allowing you through the calibration menu, it likely needs some professional attention. Sounds like the tube sensor, main bd or flakey harness. 1 Link to comment Share on other sites More sharing options...
HopeVendor Posted March 12 Author Share Posted March 12 I saw this MEI device online, and I wondered if I needed something like this to update the software Link to comment Share on other sites More sharing options...
HopeVendor Posted March 12 Author Share Posted March 12 And another thing that it is doing, and I forgot to mention this, when I put in a quarter in closed door sales mode it registers as $.24 and 2 quarters registers as $.48… Really odd! Link to comment Share on other sites More sharing options...
AZVendor Posted March 12 Share Posted March 12 Bad coin mech. Get it professionally repaired. It's not a DIY matter. 1 Link to comment Share on other sites More sharing options...
Vendo Mike Posted March 12 Share Posted March 12 Sounds like it’s been changed to another currency or factoring is messed up. Send it out for repair. 1 Link to comment Share on other sites More sharing options...
