So how do you clean a corona wire and fix a brother laser printer error? My nursing station recently purchased a Brother Monochrome laser printer (Model HL-2140) a few months ago. So far this has been a really great printer! It prints very quickly, has very clear quality, and is so much more efficient compared to an inkjet printer like my old Lexmark 3-in-1.
So far the printer has done great, however, I started getting a strange error message in the middle of printing the other day. It completely stopped printing the sheets, and a box (prompt) displayed on my computer monitor. It said, “Please Clean the Corona Wire.”
How to Clean the Corona Wire in a Brother Laser Printer HL-2140 and Fix the Error Message:
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.
