My brother hl 2140 printer today gave me an error message telling me to clean the corona wire. I've tried cleaning the corona wire many times and it still won't print. I also have a feeling that the issue isn't the corona wire because in the past I have gotten error messages talking about the corona wire when the real issue was that I was out of toner. I checked today and I'm definitely not out of toner so I have no idea what is wrong and how to fix it. A fast response would be great.
