Question about Brother HL 2140 Laser Printer
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.

Following up from Arius' advise, i tried to use a blower and thoroughly blow away the dust sparks and what not on the corona wire and then it worked perfectly. i think as Arius mentioned, the corona wire is very sensitive to dusts and particles. Therefore, as long as the wire stays clean, the printer can then work without any problem.

This is what i did.
1. remove drum cartridge
2. separate toner cartridge
3. remove small "E" clip from drum shaft at corona cleaner end
4. remove bush and push Drum shaft slightly in, enough to disengage bush at other end.
5. hold by shaft and lift drum and corona unit from drum cartridge and place on table with drum upward.
6. pull out drum shaft and remove drum watch for drum gear.
7. at the end of the corona unit which has a white disk, gently prize/slide the corona grid away from the disk. this releases the grid and it can now be lifted carefully out.
8. Use an eraser to clean the corona wire "CAREFULLY" it should be Golden colour.
9. use eraser to clean All toner stains from Grid "CAREFULL"
remove rubber roller and clean with dry cloth.

Corona wire are quite sensitive to any foreign particle like toner, or dust, spark might cause the corona to popped up, ensure the the whole assy is thoroughly clean and install a new wire, do not use any liquid material in this area, caus it is a form of conductor that might help the corona from shorting to the ground itself,
nothing to do with the toner, it might be a coincidence

New printer, about 100 pages printed - same problem: clean corona wire.

Try printing a configuration page: it should tell you what the actual amount of toner is in it.
For the message I beleive there is a sensor or voltage indicator that reads how the wire is doing wipe the inside with a clean cloth top and bottom to remove any toner that might be giving a false reading
