I’ve done a lot of electronics repair and my Brother MFC-9320CW was exhibiting the classic symptoms of a dead power supply — no lights (not even a carrier light for the Ethernet jack), no buzz, nada. So, I read several other “my printer won’t start” answers and pretty much dismissed all of them. Someone suggested to unplug, turn on the power switch (with the power disconnected), wait a minute, then connect power and turn on as normal. I told myself “that can’t possibly work,” but I’m here to say that it did. The only explanation I can fathom is that the power supply control circuits must have some logic that was reset by draining the supply of whatever residual charge it had. Live and learn!

I’ve done a lot of electronics repair and my Brother MFC-9320CW was exhibiting the classic symptoms of a dead power supply — no lights (not even a carrier light for the Ethernet jack), no buzz, nada. This machine has a traditional rocker power switch, not a software controlled “soft switch”. So, I read several other “my printer won’t start” answers and pretty much dismissed all of them.
