How do I troubleshoot issues with the YUMBI Printer?


NORMAL OPERATING SCREEN


When the YUMBI Printer is operating normally, a signal bar should be displayed on the right-hand side of the screen, as well as the letter 'G'  and an arrow in the top left-hand corner. See image provided below of a fully operational YUMBI GSM Printer. 




If you have received an SMS warning that the YUMBI Printer located in your restaurant is currently offline it is possible that one of the following scenarios has occurred. 


Please go to the YUMBI Printer and run through the scenario check-list below.

Ensure that the YUMBI Printer has been plugged into the power socket and is switched on.
