bmwmtv Cold reset
A cold reset changes most system parameters in NVRAM to the factory defaults. However,
unlike NVRAM initialization, a cold reset does not reset the page count, the paper tray sizes,
language, or formatter number.
To perform a cold reset
1. Turn the printer off.
2. Press and hold down the GO button.
3. Turn the printer on, and continue to hold the GO button for at least 5 seconds, but not
longer than 15 seconds. During this process, the Attention LED turns on.
4. Release the GO button.
