Dell 2330dn turns itself off

[not_a_techie]

I have a Dell 2330 laser and everything is fine but it has started turning off by itself, no particular time when it does it and the only way to turn it back on is to turn off at plug then turn back on. Any ideas greatly received

By turning it off "at the plug", do you mean that you unplug it?

yes i have to disconnect the power from the machine
