my epson workforce wf-2860 keeps going back to the home screen while i'm trying to use it, how do i stop that?

Yeah, this one's common. It's the Operation Time Out feature kicking in. It's set to blank the screen after a few minutes of inactivity by default.

To turn it off:

1. Press the Home button.
2. Select Settings.
3. Select General Settings.
4. Select Basic Settings.
5. Scroll down and set Operation Time Out to Off.
