First of all you need to make sure your printer is always plugged in
with the power cable you received with the printer.
If the printer is still switching off automatically, it is usually because of a weak connection.
So if you are connected to the 3G SIM, we advise you to switch to WiFi.
This can easily be done by using the following method:
MENU -> WIRELESS LAN -> SCAN NETWORK. (F1 switches between letters, capital letters and numbers. If you wish to insert one of these symbols .,,:/-_@?! press F1 and then 1.)
See (Link to "How to connect printer to the wifi") for a full guide.
If you are connected to WiFi, we advise you to turn off the WiFi as it has weak signals.
This can easily be done on the printer using: MENU -> WIRELESS LAN -> DISCONNECT.
