The E20 MG error is mainly caused by the detection of a suspicious bill. Please remove the bill and resume the count. The bill is not added to the count. (please note the magnetic ink feature of notes may become weaker when a note is old, heavily used or accidentally washed)
If you experience multiple E20 errors, please reduce the sensitivity:
> Access the Menu by pressing the OK button for 5 seconds and enter the password ↓↓↓↓
> Select Settings
> Scroll down to MG1 and press ok
> Reduce the sensitivity from 1 to 0, Press Start to save your selection
If the error persists, please contact support@deteckusa.com to advise on additional troubleshooting steps.
It will be very helpful if you can send us a video by WhatsApp +1(332) 895-2855 or email showing us the Error Notification during the count and highlighting (1) the type of bill causing the error and (2) denomination(s).
