SOURCE: 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.

SOURCE: How do i clean the drum unit corona wire

HI
Open the front door and remove the Drum unit.

On the top of the drum unit, to one side, you should see a small blue knob, mounted into a slot. This is the Corona cleaner.
Slide it back and forth a few times, and make sure you return it to the original position.
That's it.
Put it back together and try it out.
Good luck.

SOURCE: drum error keeps popping up, cleaned the corona

Hi, Sorry my english is poor, but i will try: you have to say to your machine that you change the drum, open the front end, and pull out the drum , and insert it, but before you close the front end, push the clear/back button, and answer yes,...thi is it :-)

SOURCE: OPEN THE FRONT COVER THEN CLEAN THE CORONA WIRE OF

This will solve most "Toner End Life" message problems when you know that there is toner still in the cartridge.
1. Remove the toner assembly by opening the top scanner lid, then pull(tilt) open the front panel, and pull out the toner assembly by gently grabbing the tabs and pull out with an upward motion. The toner cartridge(grey color) and the toner holder assembly (black color) will come out.
2. At the top rear of the assembly you will find a square green tab that can be slide along lengthwise of the toner. Just slide it back and forth fully several (5 to 10 times) times. I carefully blow on it as well(no spitting!) while sliding it.
3. Put the assembly back into the printer, Close the front cover, and drop the scanner cover.
4. Whala ! (usually), actually this has worked everytime for my brother and myself.

Why does my Brother HL 3070CW keeps saying "drum error, clean corona wire on drum". I have cleaned all the corona wires, but still getting the same message.


You have to replace your drum with a new one. It has been worn out and cannot keep the primary charge, resulting poor image quality

MFC 7340 - I changed the toner cartridge, and cleaned the corona wire as instructed. When I put the drum unit back in, I get the message "Open front cover clean corona wire". I clean the corona...


The drum unit may be at it's end. There is a report you can print that will say "Drum" life at the bottom of the page. I think it's the "User Settings" or something. Though it sounds like you can't print to find this out anyway....Do you recall how many times you've changed the toner without changing the drum? Usually you can expect about 4-5 toners on every drum. Once the drum's photo sensitive coating wears off it is incapable of charging correctly to print. Might just be time for regular maintenance. panderson@cartridgeworldusa.com with questions.

Fax machine has a message that says "open front cover to remove the drum. Clean the corona wire located on the drum."


The fax machine instruction must be done to erase the
message. The corona wire located on the drum needs to be cleaned.

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.

Cleaning message


the drum unit may have a full waste toner hopper, I am not sure but defintely do not clean, or touch the drum, you may touch the the drum unit which has a corona wire which occasionally may need cleaning by running a wand across it. there should be a colored clip that will slide back and forth on the drum catridge to clean it.sorry i couldn't be more helpful without actually seeing it.


Thank You,

Mikey
