All four lights flashing indicated a problem only a service center can repair.

Press the Go button and a new set of indicators will appear.

The yellow toner light only indicates a fuser unit failure.
The yellow drum light only indicates a laser unit failure.
The yellow toner light AND the red paper light indicates a main motor failure.
The red paper light only indicates a PCB failure (Printed Circuit Board).

The only thing you can do at this point is to actually UNPLUG the power cord for 24 hours and then retry or if that fails take it to a service center or better yet go pay the $89 for a new unit.

Hope this helps.

Here is the procedure for resetting the Toner flashing light on Brother HL-2140 (sources for other answers here and self testing - specific to HL-2140)
  • Open the front cover and leave open.
  • Turn the printer off.
  • Hold the "white button" while turning the printer on. (All panel lights should be on.)
  • Release the "white button".
  • Press the "white button" 2 times (Pause, wait for all lights to come on.)
  • Press the "white button" 5 times. (All lights to come on again, then go out.)
  • Cancel "maintenance driver" install, if prompted

This will:

  • restore the printing darkness (when toner light flashes, printer prints lighter to save toner)
  • keeps the printed page counts and drum life info

I have a Brother 2170w with all lights flashing. Turning on and off does not fix problem. Help!

This is in reference to another solution on this site--please search before posting as others have already solved this problem:


When all lights flash it's a service problem. You press and hold the go button and see what lights are on then.error light means main PCB failure, Toner light means fuser failure, drum light means laser failure. Toner and error light means main motor error, drum plus error light means its a fan failure.

Hi there -

The reason the drum light keeps flashing is that you have to "reset" the machine after you've installed a new drum. To do this, I believe all you have to do is make sure the printer is on and then push and hold down the "GO" button a few seconds and then the flashing will stop. This will "reset" the printer to recognize you've installed a new drum. I'm going from memory on that, but I believe that's correct. It's a really simple solution. Good luck!

Drum replaced light keeps flashing

When the print quality deteriorates and the drum light is flashing you can replace teh drum but the light will continue to flash until you reset it. Do this by opening the front of the printer and holding down the Go button for about 4 seconds until all four lights on the display are illuminated. It should be fine after that.

Drum light flash Brother HL 2070N

You need to have the front of the printer open, when you press and hold the 'Go' button. All four lights will come on, in sequence. Release the button, and close the front cover. Done...

All four lights are blinking.

It depends on what error your machine has, but it has a critical error, all four lights, usally needs fuser, sometimes laser depends on what is indicated when one presses and holds the go button either way it needs to be workshoped to enable repairs to be performed.. link to lights explain on the 2040/2070

Table below is only service errors like coyote_k has. ie all four lights then press go to identify fault.
