3 vertical dashed lines down every page


Hi there, I would assume that you are speaking about a laser printer, if this is the case you would have to take the printer in for a service and ask them to clean the primary and secondary corona wires.

A dirt corona wire can cause a vertical lines down the print job cause that part of the OPC drum is not being charged by the charge corona.
Could also be a dirty drum.

Hope this helps. :)
Please let me know.

Vertical Lines through incoming faxes and copies.


Sometimes you may see vertical streaks/black lines
on the faxes you receive. Either your FAX/MFC's
primary corona wire for printing may be dirty, or
the sending party's fax scanner may be dirty. Clean
your primary corona wire (see pages 13-18), or ask
the sender to make a copy to see if the problem is
with the sending machine.
Cleaning the Drum Unit
We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering toner.
1 Carefully turn the drum unit upside down.
2 Clean the primary corona wire inside the drum unit by gently sliding the tab
from right to left several times.
3 Return the tab to the Home
position (  ) before
reinstalling the drum unit.

Brother not printing


Hi John, the machine keeps asking you to clean the corona wire because on start up or especialy when the machine readies it's self to start printing, it passes a voltage through the corona wire which helps the drum erase the charge on the organic photo compound the drum is covered in.
If the machine sees any problem with the transfer of this voltage it thinks there is a problem.
The corona wire can be cleaned by sliding the blue tab on the top of the drum from right to left a few times.
You should check to see if this wire is broken ..it a very thin wire about the thickness of a human hair, if the wire is not broken then try cleaning the thin metal grid below the corona wire with a cotton bud , being carefull not to break the wire.
If this doesnt work then it sounds like the high voltage connection on the drum is faulty, and you will need to purchase a new drum ( or take it back to the supplier and say it is faulty and you want it replaced).
You ould also clean the surface of the drum itself carefully with a soft DRY clean cloth.
The only other cause is the high voltage supply pcb is faulty. Which if the machine is out of warranty is prohibitavely expensive to repair.

Hope this helps

Copies are black and where is this corona wire? I


Your cartridge has two sections, the drum and the toner section. The corona wire is on the drum section. There should be a blue tab on the top left hand side of your drum unit. Slide this tab across the cartridge one or two times, returning the tab to its original position. There should be an arrow on the blue tab that will match up with an arrow on the drum unit when the tab is in its resting position. Performing this action cleans the corona wire inside the cartridge. If this doesn't fix it you may need to purchase a new drum unit.

Same problem even with new Brother drum


Did you replace the drum or the toner cart? The drum has a blue lever that you slide back and forth around 20 times to clean the corona wire. I sometimes use a cotton swab with alcohol to gently clean this wire as well.

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.

Pls Clean Drum


The drum is the larger plastic unit that slides out an the toner cartridge fits into it. The corona wire is the very fine wire at the front top of the drum. Just slide the little cleaning tab back and forth.
