Printer won't print error message corona wire needs cleaning

To clean the corona wire in the brother laser printer, it said to remove the drum/toner assembly from the printer. This is very easy to do, you simply pull down the front of the printer, and press a small green tab down and pull. Then the toner and drum assembly will quickly come out.
After that, it says you must clean the corona wire by moving a small green square back and forth several times. It seemed kind of strange to me, but I did it anyways. In the upper right corner of the drum/toner assembly, there is a small green/blue square that can be moved back and forth. I did this several times.
I then placed the unit inside, and the error message went away for a minute. However it still wouldn't print and the error message came right back up. I was a bit frustrated since I have only owned this printer for about 2-3 months.
But then I realized something: The toner button had been blinking for about a month. I had already purchased a high yield black toner cartridge for the brother laser printer (Tn-330/TN360). I purchased it online, and had it stored for when I eventually ran out of toner.
I thought perhaps the error message had something to do with the old toner. Maybe it was out?? So I once again opened the front of the laser printer, and removed the toner/drum assembly. I pressed a green tab, removed the old toner, and then added the brand new high yield black laser toner cartridge. The whole process was very simple (you gotta love today's technology).
I then quickly "cleaned the corona wire" a few times again just to be safe. I re-installed the toner, and the printer was up and running. So apparently it will throw this error when you are out of toner. Now the printer is running great again, and I really like this printer.
If you are still using an ink jet printer, then you are living in the stone age. I was reluctant to buy a new laser printer, but now I love it. The toner only costs $30-60 and lasts for months. I print hundreds of labels out each month-just to give you an idea of how long it lasts.or get more information Call +877 889 6859 for detail.

The Corona wire is inside the drum unit, a small slide is there to allow you to move it back and forth. return it to it's home position when done.

Also, remove the toner and power on the machine. After a couple minutes, replace the toner and drum. This sometimes will clear up these "drum issues" Brother is famous for.

You will need to replace the drum unit on the printer.

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,
Pat

When it says to clean the corona, on the drum there is a purple tab that moves from one side to the other. run it back and forth a couple times that should solve the problem.

I dont recommend refilling the cartridges, we have had several issues in repairing those printers with refill. if you must use refills, i would recommend getting 2nd or 3rd party manufacturers.

if you need help, you can contact us.
thanks adi

this printer has 6 Drum, check all, and look internal counters is available on the menu they are down counters. If Continues go the Brother Repair Center, for repair.

The error message is misleading. The printer wants a new toner cartridge.

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.

The red lite indicates one of the following needs to be looked at:

Cover open (Front cover) Close the front cover.

Cover open (Jam clear cover) Close the jam clear cover of the fuser unit.

Memory full - Press the go button.

Print overrun - Press the go button.

Clean drum unit - Clean the corona wire.

I was getting the clean the corona wire problem message even after repeated cleanings.  Before this problem occured the toner light was flashing warning of low toner. When I got the clean the wire pop up the toner light was on all the time indicating the toner was depleated.  So, I thought I would try replacing the toner cartridge and see what happened. I opened the new toner box and noticed on the foil packege specific instructions to clean the corona wire when installing the new toner.  I installed the new toner and cleaned the wire one more time. I then reinstalled the drum and toner assembly into the printer and the clean the corona wire message did not come up again.  The printer now works fine.
