you have to take out the drum and on top of the drum unit, there is a blue color plastic which can be slide from left to right... just slide a few times from left to right...that will clean the corona wire .

Hello,
If you are getting "clean corona wire" on your PC and the toner light on the machine is solid, you need to change your toner cartridge.
This is a bug in the brother software.
Thanks,

Try using canned air to blow out that corona area, and then a Q-tip moist with alcohol to gently wipe the corona wire, if all that fails you will need a new drum.
Also press the go button 3 times so you get a printout and check that you are getting a clean the drum error or something else.

The driver should pop up a error message. Possibly is due to clean corona wire. Slide the blue lever several times across (at the drum unit).

When you experience a persistent problem like this right at the beginning - listen to your own good advice. Take it back to the store and exchange it for a new one.

You need to take out the drum and find the blue tab on top, run it back and forth about 20 times to clean the corona wire. When that doesn't help you open the door and hold the go button til all lights flash and then close door. Drum error should go away. Press go 3 times for a printed report.

SWARNAVA has the most common wrong answer to this problem...

I am waiting for a firmware update to fix this issue. The only solution is repeatedly removing the drum/toner, moving the green cleaner back and forth, putting it all back together loosely, putting it in the printer loosely, and closing the door gently. Hold down the blue button until all the lights glow, then release. If you're lucky you only have to repeat this process a dozen times until you trick the sensor into not giving false readings.
